In fight against superbugs, newly discovered antibiotic looks promising
The war against drug-resistant superbugs has been a losing battle, with scientists failing to develop any successful new antibiotics in the past three decades.
But now a team of U.S. researchers believe they are on the verge of developing a novel weapon against swiftly mutating pathogens after they discovered a new antibiotic in the soil that appears, at least in early experiments, to be an effective and enduring killer of resistant strains.
November is Lung Month! The Bowdish lab gets involved with the Breathing As One campaign.
Research in Lung health is not nearly as well funded as it should be considering the toll it takes on patients and our healthcare system. That’s why the Bowdish lab is involved in the Lung Association’s Breathing as One campaign to raise money for lung research.
IIDR Trainee Research Day 2014: Winners of the awards and scholarships
Oct. 10, 2014 - The Michael G. DeGroote Institute for Infectious Disease Research celebrated the diverse talents of its trainees and postdoctoral fellows at the fourth annual Trainee Research Day held on Friday, October 10th.
A Canadian researcher is one of four scientists raising the issue that Ebola may be silently immunizing large numbers of people, who never fall ill or infect others yet become protected from future infection. Their letter was published today in the medical journal The Lancet.
If true, this finding could have significant ramifications for both projections of how widespread the disease will be, and strategies policy makers and health workers should use to contain the disease, say the authors.
McMaster University's Jonathan Dushoff, an associate professor of biology and an investigator with the Michael G. DeGroote Institute for Infectious Disease Research, is one of the authors with principal author Steve Bellan of the University of Texas at Austin and others from UT Austin and the University of Florida.
THIS FULL-DAY EVENT will give IIDR undergraduate students, graduate students and postdoctoral fellows the opportunity to present their research and network with researchers and peers. Lunch will be provided.
McMaster postdoc is breaking down the wall of chemo side-effects
Postdoctoral fellow Erin Westman, biochemistry and biomedical sciences, will be competing against 99 young scholars, entrepreneurs and professionals from around the world at the Falling Walls Lab Finale in Berlin.
Westman was chosen from a group of 17 graduate students and postdoctoral fellows who competed at McMaster’s inaugural Falling Walls Lab.
She will take her winning presentation – Breaking the Wall of Chemotherapy Consequences – to the international competition and conference in November.
Glow of poop may shed light on diagnosing cancer
Two McMaster University researchers are looking to diagnose colorectal cancer with glowing fecal matter.
For what could become an inexpensive, simple, accurate and non-invasive test, biochemist Yingfu Li and gastroenterologist Bruno Salena are developing fluorescent DNAzymes that will detect cancer markers in stool samples. If cancer is present, the molecules will glow, leading to early treatment and better outcomes for patients.
The two hatched the idea on the golf course. Li and Salena work in different scientific fields, but discovered they share an interest in early detection of disease. Li has been studying fluorescent DNAzymes for many years, while Salena has been treating patients with colorectal cancer and other bowel diseases.
An influential international ranking of the world’s universities has placed McMaster at number 90 among the world’s universities.
The Shanghai Jiao Tong Academic Ranking of World Universities has moved McMaster up to No. 90 from 92 in 2013, making it one of just four Canadian schools in the Top 100, with the University of Toronto, the University of British Columbia and McGill.
In total, the ranking placed 21 Canadian universities among the world’s top 500 institutions — a drop from 2013, when 23 Canadian institutions made the top 500.
There are an estimated 16,000 universities in the world.
Fungicides linked to resistance in life-threatening fungus
Amid growing concern that fungicides are fuelling the rise of resistant and life-threatening fungus in Europe, China and India, a microbial sleuth says it is time to start filling in the gaps in Canada.
As a first step, biologist Jianping Xu says his group at McMaster University in Hamilton, Ont., hopes to start testing fungi circulating in southern Ontario’s farm belt this fall.
“We plan to take samples in the environment and compare them with what we see in patients in the hospital,” says Xu, who has collaborated on several international studies that point to resistant fungi as a growing and serious health threat. Read more...

Antibiotic-Resistant Germs, Lying in Wait Everywhere
The Lechuguilla Cave in New Mexico is a network of chambers stretching 1,600 feet underground. The bacteria that grow on the walls of its most remote recesses have been living in complete isolation for more than four million years.
In 2010, Gerry Wright, a microbiologist at McMaster University in Ontario, ran an experiment on those long-lost bacteria. He and his colleagues doused them with antibiotics, the drugs that doctors have used for the past 70 years to wipe out bacterial infections. Read more...
Kryptonite for superbugs: Scientists unearth what may be a secret weapon in the urgent battle against antibiotic-resistance
HAMILTON, ON, June 25, 2014—A fungus living in the soils of Nova Scotia could offer new hope in the pressing battle against drug-resistant germs that kill tens of thousands of people every year, including one considered a serious global threat.
A team of researchers led by McMaster University has discovered a fungus-derived molecule, known as AMA, which is able to disarm one of the most dangerous antibiotic-resistance genes: NDM-1 or New Delhi Metallo-beta-Lactamase-1, identified by the World Health Organization as a global public health threat.
“This is public enemy number one,” explains Gerry Wright, director of the Michael G. DeGroote Institute for Infectious Disease Research at McMaster University.
“It came out of nowhere, it has spread everywhere and has basically killed our last resource of antibiotics, the last pill on the shelf, used to treat serious infections,” he says.

McMaster team wins first Synapse Life Science Competition
A McMaster University spin-off company has won a new competition for life science businesses. Advanced Theranostics Inc. took first place in the inaugural Synapse Life Science Competition this week.
The winning presentation was about a solution to the need for faster, more sensitive lab diagnostics for infectious diseases through a DNA swab, a hand-held device and a mobile app.
It’s supposed to be a simple household task, meant to divert organic material from the landfill.
But composting is often anything but pleasant. From the hordes of fruit flies that swarm above the green bin to the compostable bin liners that inevitably dissolve, spilling slime on hands, kitchen counters and floors, composting is often a dirty, smelly job.
And that, says Morgan Wyatt, is why the world needs the Greenlid.
The simple product – a container made of compressed pulp with a reusable lid – is the brainchild of Wyatt, a McMaster post-doctoral fellow (in the lab of Nathan Magarvey, member of the Michael G. DeGroote Institute for Infectious Disease Research), and his brother Jackson. And its usefulness is summed up in its slogan: “Never clean your compost bin again.”
Microbial Communities of the Body in Health and Disease
The Hamilton Association for the Advancement of Literature, Science and Art is sponsoring a free public talk on "Microbial Communities of the Body in Health and Disease" by Michael Surette, a microbiologist with the Farncombe Family Institute for Digestive Health Research and member of the Michael G. DeGroote Institute for Infectious Disease Research. His talk will take place Saturday, March 8 at 8 pm in Rm. 1A1, Ewart Angus Centre, MUMC. Q & A with coffee and cookies. No reservations required.

IIDR trainee publishes “how to” guide for bioinformatics
Fiona Whelan, a graduate student in IIDR member Mike Surette’s lab, has published a review article called “A guide to bioinformatics for immunologists” in Frontiers Immunology.
“The idea of this article spawned from research that I conducted in the Bowdish lab on the elucidation of the evolutionary history and relationships between the members of the class A scavenger receptors, proteins required for host defense and homeostasis,” says Whelan.
Research in the labs of Charu Kaushic, professor of Pathology and Molecular Medicine, and Lori Burrows, professor in the Department of Biochemistry and Biomedical Sciences, is set to accelerate as the result of five years of funding from the Canadian Institutes for Health Research (CIHR).
The IIDR welcomes Dominik Mertz to its membership. Mertz is a an assistant professor at McMaster, in the Division of Infectious Diseases and in the Department of Clinical Epidemiology and Biostatistics and acts as the Medical Director of Infection Prevention and Control at Hamilton Health Sciences.
His particular research interest is the epidemiology of hospital-acquired infections and of antibiotic-resistant pathogens, and antimicrobial stewardship. He also teaches at the undergraduate (MD program), graduate (Health Research Methodology) and postgraduate level at McMaster.
Scientists reveal cause of one of the most devastating pandemics in human history
An international team of scientists has discovered that two of the world’s most devastating plagues – the plague of Justinian and the Black Death, each responsible for killing as many as half the people in Europe—were caused by distinct strains of the same pathogen, one that faded out on its own, the other leading to worldwide spread and re-emergence in the late 1800s.
These findings suggest a new strain of plague could emerge again in humans in the future.
“The research is both fascinating and perplexing, it generates new questions which need to be explored, for example why did this pandemic, which killed somewhere between 50 and 100 million people die out?” questions Hendrik Poinar, associate professor and director of the McMaster Ancient DNA Centre and an investigator with the Michael G. DeGroote Institute for Infectious Disease Research.
Fever-reducing medications may aid spread of influenza
Contrary to popular belief, fever-reducing medication may inadvertently cause more harm than good.
New research from the Michael G. DeGroote Institute for Infectious Disease Research has discovered that the widespread use of medications that contain fever-reducing drugs may lead to tens of thousands more influenza cases, and more than a thousand deaths attributable to influenza, each year across North America. These drugs include ibuprofen, acetaminophen and acetylsalicylic acid.
Working with a more than 160-year-old sample of preserved intestine, researchers at McMaster University and the University of Sydney have traced the bacterium behind a global cholera pandemic that killed millions – a version of the same bug that continues to strike vulnerable populations in the world’s poorest regions.
Using sophisticated techniques, the team has mapped the entire genome of the elusive 19th century bacterium. The findings are significant because, until now, researchers had not identified the early strains of cholera, a water-borne pathogen. The discovery significantly improves understanding of the pathogen’s origin and creates hope for better treatment and possible prevention.
Ortega lab demonstrates power of electron microscopy
Joaquin Ortega and his team recently published two papers that show the power of electron microscopy to understand the workings of cellular enzymes.
“This is essential information needed to develop for example new antibiotics or to understand why cancer cells continuously divide and cause tumors”, says Ortega, a structural biologist with the Michael G. DeGroote Institute for Infectious Disease Research.
In the journalScience News, award-winning news correspondent Ann Gibbons tells the tale of researchers who have opened a remarkable window into centuries of health and disease in Europe, from the Black Death of the 14th Century to a cholera epidemic in the 19th, at the Abbey of St. Peter in Lucca, Italy.
The researchers, led by Giuseppe Vercellotti and Clark Larson from Ohio State University and Hendrik Poinar from McMaster University's MG DeGroote Institute for Infectious Disease Research, are analyzing skeletons, teeth and ancient DNA from graveyards around the Abbey in order to learn how epidemics such as the bubonic plague spread through Europe. The Abbey lay along an early pilgrimage route, where knights, clerics, monks and peasants -- as well as pathogens -- all congregated.
Secrets in the Bones: The Hunt for the Black Death Killer
It was called the Black Death, a disease that started with the spitting of blood and ended in just days with blackened extremities, delirium and death. In the 14th century it swept across Europe wiping out half the population, one of the most lethal killers in human history.
But for more than 660 years the cause of the Black Death has eluded scientists. Now, Hendrik Poinar, an evolutionary biologist based at Hamilton’s McMaster University and member of the Michael G. DeGroote Institute for Infectious Disease Research, leads an international team on an epic quest from a Black Death gravesite in Italy, to a top secret government laboratory in the United States, to a repository holding more than 20,000 sets of human remains in London. His goal: Capture the Black Death killer and unlock the secrets of this deadly disease, secrets that could help us fight infectious diseases today and, potentially, save lives.
Coombes’ lab collaborates with Qu Biologics to study new Crohn’s disease research model
Brian Coombes, associate professor in the Department of Biochemistry and Biomedical Sciences at McMaster University, will lead a new study with Qu Biologics Inc., a biopharmaceutical company in Vancouver, British Columbia, to investigate new treatments for Crohn’s disease, an inflammatory bowel disease that inflicts more than 100,000 Canadians.
Gerry Wright, scientific director of the Michael G. DeGroote Institute for Infectious Disease Research, is featured on the latest episode of CBC's Marketplace entitled "Food Secrets." In the episode, Wright talks about his unfortunate contact with antibiotic-resistant salmonella and his work in the lab to fight these and other superbugs.

IIDR celebrates its trainees
The Michael G. DeGroote Institute for Infectious Disease Research celebrated the diverse talents of its trainees and postdoctoral fellows at the third annual Trainee Research Day held on Friday, Oct. 18.
Researchers at McMaster University are addressing the crisis in drug resistance with a novel approach to find new antibiotics.
“We have developed technology to find new antibiotics using laboratory conditions that mimic those of infection in the human body,” said Eric Brown, professor in the Department of Biochemistry and Biomedical Sciences.
He is the lead author of the paper published in the online edition of Nature Chemical Biology. Brown is also a member of the Michael G. DeGroote Institute for Infectious Disease Research (IIDR).
Michael Surette, a researcher with the Michael G. DeGroote Institute for Infectious Disease Research and Farncombe Family Digestive Health Research Institute, is featured on CTV News in a segment that explores the use of fecal transplants to treat inflammatory bowel diseases. While studies show that fecal bacteria may help with obesity and depression, he warns about the risks of infection. Click here to watch the video.
An earlier segment on CTV featured a McMaster study that involved 120 participants suffering from ulcerative colitis who receive fecal material from specially screened donors. "In this trial, unfortunately it’s not 100 per cent successful," said Surette, who is studying the dozens of bugs found in the stool samples from donors. "We are starting to analyze some of the microbiology, and I think we will have some information on what’s effective and what’s not."
A tuberculosis vaccine developed at McMaster University offers new hopes for the global fight against tuberculosis.
“We are the first to have developed such a vaccine for tuberculosis,” said Dr. Fiona Smaill, professor and chair of the Department of Pathology and Molecular Medicine of the Michael G. DeGroote School of Medicine at McMaster. She led the phase one clinical study published in the journal Science Translational Medicine.
Michael Kamin Hart Scholarship propels thirst for research
Brian Tuinema, a first-year PhD student in the Michael G. DeGroote Institute for Infectious Disease Research, has a thirst for science not unlike that demonstrated in Michael Hart, a promising second-year Master’s student in former IIDR member Justin Nodwell’s lab, who passed away after a courageous battle with lymphoma in 2011.
McMaster researchers discover new microbe near Chilean coastal faultline
A team of researchers from McMaster and the University of Concepción are shining a light on rare sulfur-loving microbes off the coast of Chile.
The group's work near coastal fault lines has identified a previously unknown type of molecule, macplocimine A, whichproduces valuable natural chemicals that are known to function as effective cancer therapies and antibiotics.
McMaster University researchers are using a new approach to discover antibiotic-resistant drugs at a time when other scientists are quickly running out of options. Researchers in the Brown and Bowdish laboratories in the Michael G. DeGroote Institute for Infectious Disease Research targeted the cell membranes of MRSA (methicillin-resistant Staphylococcus aureus), a bacteria responsible for increasing the number of life-threatening infections both in the hospital and the broader community.
The research, entitled Collapsing the proton motive force to identify novel synergistic combinations against Staphylococcus aureus, appears in today’s online edition of Chemistry & Biology.
Antibiotic resistant bugs kill thousands yearly in U.S.
For the first time, the U.S. government is estimating how many people die from drug-resistant bacteria each year — more than 23,000, or about as many as those killed annually by flu.
The figure was released Monday by the Centers for Disease Control and Prevention to spotlight the growing threat of germs that are hard to treat because they've become resistant to drugs.
Finally estimating the problem sends "a very powerful message," said Dr. Helen Boucher, a Tufts University expert and spokeswoman for the Infectious Diseases Society of America. "We're facing a catastrophe."
Researchers find weather patterns play significant role in seasonal influenza
Influenza is like a cloud, moving across Canada with the fall weather, McMaster University researchers have found.
They have established that the spread of seasonal flu in Canada is tied to low temperature and low humidity and travels west to east, findings that may have significant implications on prioritizing control measures such as the timing of introducing vaccination programs across the country.
IIDR members and trainees are encouraged to attend the McMaster World Sepsis Day Symposium on Friday, September 13th in the Great Hall in the McMaster University Faculty Club.
This full-day symposium coincides with World Sepsis Day and will include a variety of sessions and panel discussions that will be interactive and inter-professional. The objective of the day is to facilitate knowledge exchange among interdisciplinary and inter-professional health care providers and researchers. Common themes identified through symposium discussions will help catalyze development of collaborative pediatric sepsis research and/or quality improvement initiatives.
McMaster researchers receive breast cancer funding
Canadian Breast Cancer Foundation (CBCF) is building on its commitment to fund high quality research across the breast cancer continuum, by investing $8.4 million in projects across Ontario, including grants to both Ali Ashkar, member of McMaster's Michael G. DeGroote Institute for Infectious Disease Research and Jessica Cockburn, a post-doctoral fellow in McMaster's Department of Oncology.
For many researchers, a love for science sparked early: some found inspiration through their parents or a teacher, others were bitten after seeing something inventive on television, while others were born with it. For Eisha Ahmed, a 17-year-old high school student working in the labs of IIDR researchers Dawn Bowdish and Mike Surette this summer, the passion was evident from an early age when she pinned insects to Styrofoam to study their intricate inner workings.
Bowdish lab starts preclinical trials on study of chronic inflammation associated with macrophage dysfunction
Dawn Bowdish, Assistant Professor of Pathology and Molecular Medicine and member of the McMaster Institute for Infectious Disease Research and McMaster Immunology Research Centre, will collaborate with Qu Biologics Inc., a biopharmaceutical company located in Vancouver, British Columbia, to research the effect of SSI therapy on macrophage immune dysfunction. Qu Biologics will test whether its SSI therapy can reduce or eliminate chronic inflammation related to macrophage dysfunction.
Ryan Lamers, a postdoctoral researcher in the lab of Lori Burrows, Biochemistry and Biomedical Sciences Professor and member of the Michael G. DeGroote Institute for Infectious Disease Research, was awarded a two-year CIHR Postdoctoral Fellowship in the most recent competition.

The IIDR Trainee Day is sponsored by Fisher Scientific, FEI/SFR, Invitrogen, Biorad, Edge Scientific, VWR, Dlamed and the Michael G. DeGroote Institute for Infectious Disease Research.
Behaviour change may have greatest influence on waves of influenza outbreak
Three waves of the deadliest influenza pandemic in history, known as the Spanish flu, hit England and Wales in 1918, just as World War 1 was coming to an end.
Why flu arrives in multiple waves like this is the focus of a study by McMaster University researchers who discovered three contributing factors: the closing and opening of schools, temperature changes and – most importantly – changes in human behavior.
“We found all three factors were important in 1918 but that behavioural responses had the largest effect,” said David Earn, an investigator with the Michael G. DeGroote Institute for Infectious Disease Research, and a professor in McMaster’s Department of Mathematics and Statistics.
Peer review examines role of antibiotics in nature
Steve Bernier, a postdoctoral researcher working in the lab of Michael Surette, investigator with McMaster University’s Michael G. DeGroote Institute for Infectious Disease Research and Farncombe Family Digestive Health Research Institute, joined leading researchers from around the globe to review literature associated with the role of antibiotics in nature. The review is published in the journal Frontiers in Microbiology (Research topic – Antimicrobials, Resistance and Chemotherapy).
Top career award recognizes global impact of antibiotic resistance research
In a career devoted to combating antibiotic resistance and seeking ways to overcome infectious disease, Gerry Wright has made a mark. This week he is being recognized for his impact with a top career award presented annually by the Canadian Society of Microbiologists (CSM).
It is another accolade to add to the scientific director of McMaster University’s Michael G. DeGroote Institute for Infectious Disease Research’s lengthy biography, which includes more than 180 papers and book chapters, countless awards and affiliations with some of the world’s most influential institutions.
Researchers dig deep into Cystic Fibrosis drug resistance
Researchers are beginning to better understand antibiotic resistance in Cystic Fibrosis (CF) patients, by investigating multiple strains of isolates taken from those inflicted with Pseudomonas aeruginosa, the primary pathogen that causes chronic lung infections.
The finding comes from the lab of Michael Surette, investigator with the Michael G. DeGroote Institute for Infectious Disease Research and Canada Research Chair in Interdisciplinary Microbiome Research, and could have significant implications for antibiotic therapy.
This summer, the Michael G. DeGroote Institute for Infectious Disease Research (IIDR) is boosting research experience for 12 trainees working in the labs of its members and affiliated institutions.
The IIDR has presented nine fellowships to trainees working in IIDR labs as well as three joint fellowships to students working jointly with IIDR members and researchers in the Farncombe Family Digestive Health Research Institute.
McMaster University researchers are breaking ground in mining the fruits of the genome revolution by developing the world’s first one-stop shopping resource to collate the scores of data associated with antibiotic resistance accumulated since the first bacterial genome sequence more than 15 years ago.
McMaster University investigators have opened up a new area of research in the study of Crohn’s Disease, a chronic inflammatory bowel disease that afflicts over 100,000 Canadians, one of the highest rates worldwide.
Led by Brian Coombes, Associate Professor in the Department of Biochemistry and Biomedical Sciences and member of the Michael G. DeGroote Institute for Infectious Disease Research (IIDR), his group has been studying a variant of E. coli called adherent-invasive E. coli (AIEC) that is associated with human Crohn’s Disease. In their new work, Coombes’ group developed a new mouse model that showed that Crohn’s-associated E. coli could cause chronic infection in the mouse gut. Interestingly, after infection the mice developed chronic gut inflammation that resembled that seen in human Crohn’s Disease. This new model will allow researchers to understand the effects of chronic colonization on the host immune system and how this might play a role in disease development.
Congratulations to the many trainees from the Michael G. DeGroote Institute for Infectious Disease Research who won awards at the 2013 Faculty of Health Sciences (FHS) Research Plenary, as well as to Ali Ashkar, Associate Professor of Pathology and Molecular Medicine, who received the FHS Excellence in Graduate Student Supervision Award.
New therapies show signs of turning immune system into cancer-fighting weapon
Jonathan Bramson, director of McMaster’s Immunology Research Centre and member of the Michael G. DeGroote Institute for Infectious Disease Research, is hopeful new immunotherapy medications designed to trigger the body’s immune system, allowing it to fight the cancer on its own, are just the beginning of what could be a powerful way to activate the immune system against cancer.
“We’re seeing seen remarkable outcomes and evidence of what we long believed: that the immune system can fight cancer,” he tells CTV News. “I’ve been a scientist in this area for 20 odd years, and much of the promise has come from animal studies. To be living in an era where we have evidence the immune system can treat cancer, it’s a very exciting time.” (Files from CTV News)
In 2007, having just completed a thesis project in virology in the lab of Karen Mossman, member of the Michael G. DeGroote Institute for Infectious Disease Research (IIDR) and Pathology and Molecular Medicine Professor, Nicole Robbins was en route to becoming a virologist at the University of Toronto. Along the way her passions changed and this year she returned to the Wright lab with a new focus.
Study suggests alternate methods of TB vaccination
A new study by researchers from the Michael G. DeGroote Institute for Infectious Disease Research suggests the importance of studying both innate and adaptive arms of host defense in TB vaccine research.
Researchers with the Michael G. DeGroote Institute for Infectious Disease Research (IIDR) have opened doors to better understand the assembly process of the ribosome, by making a new observation that may significantly impact the way scientists target bacteria.
“In this work we studied the last stages of maturation of the bacterial ribosome, the enzyme that synthesizes proteins in the cells,” explains Joaquin Ortega, associate professor of Biochemistry and Biomedical Sciences, about a paper published this month in RNA. His team involved researcher Vivian Leong and graduate students Meredith Kent and Ahmad Jomaa.
Antibiotic resistance is a worsening problem for us, but a natural and ancient phenomenon, argues Gerard Wright in a Question and Answer article published today inBMC Biology. The inevitable emergence and spread of resistance in human pathogens can only be met by the development of new drugs, yet there are few new antibiotics coming to market or in clinical trials. It can take up to a decade to bring a new drug from the lab to the pharmacy, so the problem is likely to exist for some time to come.
Through the Leaders Opportunity Fund from the Canadian Foundation for Innovation, McMaster biochemists Alba Guarné and Murray Junop, a member of the Michael G. DeGroote Institute for Infectious Disease Research, have created a state-of-the-art crystallization and diffraction facility.
By integrating tools and technologies – from genomics to small molecules – to target drugs from nature, investigator Nathan Magarvey is helping build a culture of innovation at McMaster University.
As a result, Magarvey, a member of the Michael G. DeGroote Institute for Infectious Disease Research (IIDR) and Assistant Professor in the Departments of Biochemistry and Biomedical Sciences and Chemistry & Chemical Biology, has been named McMaster’s Innovator of the Year.
Trainees from the Michael G. DeGroote Institute for Infectious Disease Research are embracing the spirit of collaboration.
A team of approximately 20 trainees from a diverse range of labs, including academic supervisors Nathan Magarvey, professor in the Departments of Biochemistry and Biomedical Sciences and Chemistry & Chemical Biology and Mike Surette, professor in the Department of Medicine and Biochemistry and Biomedical Sciences, will compete in the International Genetically Engineered Machine (iGEM) Competition on Oct. 4-6 in Toronto.
Faculty of Health Sciences celebrates its students
Faculty of Health Science graduate students and postdoctoral fellows are being celebrated this week during an annual Research Plenary, an open forum event that includes more than 400 poster and oral presentations.
The event is being held from May 14-16 in the Health Sciences library and winning posters will be on display in the Jan and Mien Heersink Reading Pavilion the afternoon of Thursday, May 23, followed by an awards reception.
Pictured during the opening poster session, from left, are first-year PhD students Brian Tuinema (Coombes lab) and Fiona Whelan (Surette lab).
Hendrik Poinar, an assistant professor in McMaster's Department of Anthropology and member of the Michael G. DeGroote Institute for Infectious Disease Research, believes that ancient DNA holds the answers to a host of major scientific questions: Did the first peoples come to North America in a single migration, or several? What were the pre-Columbian diseases on this continent? Were there dietary differences between the sexes in archaic hunter-gatherer populations?
Lab discovers path to extreme antibiotic resistance in Pseudomonasaeruginosa
Combining two mutations in non-essential genes can lead to extreme antibiotic resistance in Pseudomonas aeruginosa, one of the leading causes of hospital-inquired infections.
These findings come from a new study published in the journal Antimicrobial Agents and Chemotherapy, led by Lori Burrows, McMaster biochemistry professor and member of the Michael G. DeGroote Institute for Infectious Disease Research and her trainees Joseph Cavallari and Ryan Lamers.
IIDR members David Earn, professor of mathematics and statistics, and Eric Brown, professor and chair of the Department of Biochemistry at McMaster, joined a recent TEDx McMaster U panel to discuss "Visualizing and modelling contagion" and "Taking on superbugs with new insights into uncharted biology", respectively.

Antibiotic progress on superbugs called 'alarmingly slow'
Gerry Wright, scientific director of the Michael G. DeGroote Institute for Infectious Disease Research, comments on CBC News about a recent Infectious Diseases Society of America progress review on the development of new drugs, which found only two new antibiotics had been approved since 2009.
"We have spent several years hunting around Canada and around the world to isolate new bacteria and pull out from them as many compounds as we can," Wright says in the article.
Wright is using new technology that can screen hundreds of compounds at the same time. He hopes it will speed up the challenging search. (Source: CBC News)
The University officially opened the Biointerfaces Institute, Canada's first facility for developing unique new surfaces, using high-speed robots and other leading-edge technology. IIDR member John Brennan, professor and Canada Research Chair in Bioanalytical Chemistry and Biointerfaces, will lead a team of 10 core faculty members.
IIDR member Fred Capretta, Associate Director of the Biointerfaces Institute, talks about the the facility's capabilities in the video below, including the ability to develop materials such as hospital doorknobs that can repel bacteria, bandages that can heal wounds, home test kits for cholesterol and contact lenses that rarely need changing.

Vaccines: Truths & Myths
Vaccines save lives. In fact, they save millions of lives a year and prevent diseases like polio, measles and mumps from making a dangerous comeback. Yet, childhood immunizations continue to be avoided by many people around the world for fear that they overwhelm the immune system, cause autism and contain dangerous preservatives.
Community members are invited to join in a lively and informal discussion to help sort the facts from fiction with leading experts from McMaster University’s Immunology Research Centre and the Michael G. DeGroote Institute for Infectious Disease Research.
The free event, titled Vaccines: Truths & Myths, will take place April 29 from 7-9 pm at the Royal Botanical Gardens.
McMaster celebrates Royal Society of Canada Fellows
Over the last five decades, 80 members of McMaster’s research community have earned one of the country’s highest academic accolades available to leading intellectuals, scholars, researchers and artists – election to a Fellowship in the Royal Society of Canada (RSC).
Gerry Wright, Scientific Director of the Michael G. DeGroote Institute for Infectious Disease Research, joined this esteemed group in 2012 and was honoured at a recent event celebrating McMaster’s Fellows of the RSC, hosted by President Patrick Deane and Vice-President, Research & International Affairs, Mo Elbestawi.
IIDR member and McMaster evolutionary geneticist Hendrik Poinar speaks about bringing the woolly mammoth back to life during a TEDx Conference on DeExtinction in Washington on March 15.
Drug rocks the boat
A ‘gold-standard’ drug has been found to have a secondary mode of action, as not only does it inhibit antibiotic efflux pumps, responsible for pumping toxic substances and antibiotics out of the cell and major contributors to multi-drug resistance, but also punches holes in membranes, causing resistance enzymes to leak out.
Biochemistry and Biomedical Sciences Professor Lori Burrows, a member of the Michael G. DeGroote Institute for Infectious Disease Research (IIDR) and her postdoctoral researcher Ryan Lamers, recently discovered that Phenylalanine-Arginine Beta-Naphthylamide (PAbN) can punch holes in bacterial membranes, causing resistance enzymes normally found inside the bacteria to leak out and rendering the bacteria more susceptible, independent of efflux inhibition.
Undergraduate Student Research Awards push interest in science
Two undergraduate students in the Michael G. DeGroote Institute for Infectious Disease Research have received Undergraduate Student Research Awards through the National Sciences and Engineering Research Council of Canada, allowing them to continue to work alongside their mentors over the summer months.
Gerry Wright, Scientific Director of the Michael G. DeGroote Institute for Infectious Disease Research, commentates in the Toronto Star about the ongoing threat of antibiotic resistance and need for urgent action.
His commentary follows the Ontario Medical Association report titled “When Antibiotics Stop Working,” (see story below) calling on the provincial and federal governments to address this growing crisis of antibiotic resistance while there is still time.
Ontario's doctors: antibiotic resistance poses major threat to public health
On March 20, 2013 the Ontario Medical Association released a report titled "When Antibiotics Stop Working," with recommendations about how government and the health community should respond to antibiotic resistance. Ontario’s doctors warn that the over-use of medicines weakens doctors' ability to save human lives and they call on federal and provincial governments to immediately enact regulatory changes that will help to reverse this threat by reducing the growth of antibiotic resistant bacteria.
The doctors know what they’re talking about in warning against overuse of antibiotics, says Gerry Wright, scientific director of the Michael G. DeGroote Institute for Infectious Disease Research. He says antibiotic resistant bacteria are being found everywhere, even in dirt.
“As a society we’re are not used to finding that what did cure people doesn’t work anymore. These recommendations of the physicians are important to raise awareness of how we all need to respond now, as we search out new ways to fight antibiotic resistance.”
The Michael G. DeGroote Institute for Infectious Disease Research (IIDR) recognized two promising young scientists during the recent Bay Area Science and Engineering Fair.
Eisha Ahmed, a Grade 12 student of Abbey Park High School in Oakville, was the first place winner of the IIDR prize that recognized the best senior project in infectious disease, drug discovery or human health.

Nathan Magarvey, member of the Michael G. DeGroote Institute for Infectious Disease Research and assistant professor of Biochemsitry and Biomedical Sciences, has been awarded a new Canada Research Chair.
As Canada Research Chair in Natural Product Drug Discovery (Tier 2) Magarvey will use a number of integrated tools and technologies – from genomics to small molecules – to target drugs from nature. His focus will be to mine these natural source materials for new bioactive compounds, so they can be produced into a more efficacious and targeted therapy for diseases.
Former IIDR trainee Herlinder Takhar has published a paper in the Journal of Biological Chemistry describing the characterization of a critical component of the motor that powers bacterial “twitching” motility through retraction of fibers called type IV pili.
The paper, by the recent Masters student in the lab of Lori Burrows, biochemistry professor and member of the Michael G. DeGroote Institute for Infectious Disease Research, resolves a debate about which protein connects the cytoplasmic enzymes that provide the energy for movement to the rest of the pilus assembly system.
Takhar held a Canadian Institutes of Health Research (CIHR) Frederick Banting and Charles Best Canada Graduate Scholarship and an Ontario Graduate Scholarship. She is now working as a Supply Center Specialist with Life Technologies.

Public health role in controlling infectious disease outbreaks focus of panel discussion
Common viral infections such as a cold or the flu are something we all have to deal with in everyday life, and most of the time are not cause for alarm. However, some viral infections, such as HIV and particular strains of influenza, can become extremely dangerous or even fatal.
With our increasingly mobile society, the risk of outbreaks of infectious diseases that can create global health threats, such as happened with SARS and H1N1, has led to an increased emphasis on public health policy as it relates to controlling pandemics.
National Geographic News asked Hendrik Poinar, a molecular evolutionary geneticist and biological anthropologist at the Ancient DNA Centre at McMaster University and member of the Michael G. DeGroote Institute for Infectious Disease Research, if we might soon see the gigantic land mammals roaming the steppe again. Poinar will speak about the emerging technology at the TEDx Conference on DeExtinction in Washington on March 15.
David M. Shlaes, an international expert in the field of antimicrobial resistance research, has joined the External Scientific Advisory Board (SAB) of the Michael G. DeGroote Institute for Infectious Disease Research (IIDR).
The Scientific Advisory Board consists of accomplished and distinguished members of the scientific community considered internationally respected leaders in infectious disease and antimicrobial research.
Popular drug faces resistance in a common fungal pathogen
Resistance has taken another victim, this time one of the world’s most common antifungal medications used to treat upper-respiratory illness and air-born allergens.
The drugs, called triazoles, have been shown to be ineffective against a common fungal pathogen called Aspergillus fumigatus in several parts of India. Researchers have determined that the most likely cause for the origin and spread of the resistance is the heavy application of agricultural fungicides.
Researchers create novel approach to identify chemicals bacteria "see"
Researchers from McMaster University’s Michael G. DeGroote Institute for Infectious Disease Research have devised a new way to identify the molecules, including antibiotics, that bacteria sense.
Developed by Leslie Cuthbertson, a postdoctoral fellow working with Justin Nodwell, Professor of Biochemistry & Biomedical Sciences, the new process predicts chemicals recognized by members of an important family of transcription factors, called “the TetR family”. They incorporated more than 4,000 proteins to create a framework for identifying these chemical/protein interactions. They then used this framework to successfully identify an antibiotic molecule for a transcription factor of unknown function, showing that the gene regulated in response to this antibiotic encodes a novel antibiotic resistance protein.
His original plans had more to do with sonatas and concert halls than science.
“I wanted to be a concert pianist when I was a little kid,” says Justin Nodwell, Professor of Biochemistry and Biomedical Sciences and member of the Michael G. DeGroote Institute for Infectious Disease Research (IIDR) at McMaster University. “In fact, I was sure that was what I was going to do until I was 14. I took lessons and exams and all that sort of thing; my heroes were Glenn Gould and a bunch of dead composers. It really was my life. And then I bombed the Collegiate II piano exam at McGill and decided it was all over.”
From studying the effects of Vitamin D supplements as a way to prevent influenza to understanding the assembly process of the ribosome as a target for new antibiotics, the Michael G. DeGroote Institute for Infectious Disease Research is set to make exciting new scientific discoveries in 2013.
Five projects have been selected for seed funding in 2013, including projects by members Mark Loeb, David Earn and Ben Bolker and Eric Brown and Joaquin Ortega, Hendrik Poinar and James Mahoney.
Each team will present a summary of their findings at IIDR’s Annual General Meeting on April 24, 2013 at the Ancaster Mill.

Scientists discover new small molecules that protect bacteria against toxic gold
McMaster researchers have discovered that gold resistant bacterium Delftiaacidovorans can turn toxic water-soluble gold into a solid gold form, the first demonstration that gold-resistant microbe secretes a metabolite that can protect against toxic gold.
The research, published in NatureChemicalBiology, was led by Nathan Magarvey, an investigator with the Michael G. DeGroote Institute for Infectious Disease Research at McMaster University and Assistant Professor in the Departments of Biochemistry and Biomedical Sciences and Chemistry & Chemical Biology.
Research stresses importance of broadening HIV prevention strategies
A new study that measures the importance of different routes of transmission in 18 African countries and regions provides support for an aggressive ‘test and treat’ approach which would seek to identify and offer treatment to all HIV-positive individuals in Africa.
“By investigating what can be learned about routes of heterosexual transmission in sub-Saharan Africa from large-scale survey data we found that pre-couple, within-couple and extra-couple transmission are all important,” says Jonathan Dushoff, Associate Professor of Biology at McMaster University, member of the Michael G. DeGroote Institute for Infectious Disease Research, and senior author on the study released online this week by Lancet
Evolutionary geneticist and IIDR member Hendrik Poinar was featured on the CBC Radio show Q last week.
The show, a daily arts, culture and entertainment program hosted by Jian Ghomeshi, was taped Thursday night in front of a live audience at Mohawk College's McIntyre Performing Arts Centre.
Poinar, an associate professor of anthropology and director of McMaster's Ancient DNA Centre, recently made headlines when he and a team of researchers sequenced the entire genome of the Black Death. He has also mapped the genome of the wooly mammoth.
Past and present lab members of Gerry Wright, Director of the Michael G DeGroote Institute for Infectious Disease Research, celebrated 20 years of "Doing it the Wright Way," on Friday, Jan. 25.

Top IIDR students receive esteemed fellowship
In the lab, Ryan Lamers is on a constant quest to stay one step ahead of the third most dangerous pathogen afflicting Canadian hospitals.
“We study the mechanisms of antibiotic resistance in Pseudomonas aeruginosa, which is quite prevalent in cystic fibrosis patients but is very resistant to antibiotics,” says Lamers, a postdoctoral researcher in the lab of Professor Lori Burrows, a member of the Michael G. DeGroote Institute for Infectious Disease Research (IIDR). “My overarching goal, the reason I come in each day, is to stay ahead of the Pseudomonas pathogen that is quite opportunistic in hospitals and one of the top three pathogens that infect people in hospitals.”
Researchers find age not factor in immunity to viruses
Our immune system does not shut down with age, says a new study led by McMaster University researchers.
A study published in PLOS Pathogens today shows a specialized class of immune cells, known as T cells, can respond to virus infections in an older person with the same vigour as T cells from a young person.
“For a long time, it was thought the elderly were at a higher risk of infections because they lacked these immune cells, but that simply isn’t the case,” said Jonathan Bramson, the study’s principal investigator and member of the Michael G. DeGroote Institute for Infecious Disease Research. “The elderly are certainly capable of developing immunity to viruses.”
Mushroom not main cause of mystery deaths in China: McMaster researcher
Jianping Xu is featured in CBC.ca today for his research that debunks a theory that some 400 people in southwestern China died mysterious, sudden deaths from eating a toxic mushroom.
Xu has spent the last four summers climbing mountains and slogging through forests in search of the Trogia venenata, a mushroom once suspected of causing fatal heart attacks with its high concentration of the metal barium.
'Fecal transplants' used to treat C. difficile cases in Hamilton
It's unnerving, it's invasive and it's extremely awkward to talk about, but a controversial procedure being performed at St. Joseph's Hospital in Hamilton is saving lives.
Dr. Christine Lee has been giving fecal transplants in Hamilton since 2008.
The treatment, used to treat C. difficile, involves introducing stool from a healthy donor into an infected patient's bowel, usually through an enema.
Lee, member of the Michael G. DeGroote Institute for Infectious Disease Research and the medical director of infection prevention and control at St. Joseph's Hospital, started using the procedure to treat C. difficile cases in patients who weren't responding to regular therapy.
“We were running out of options,” she said. So fecal transplants were implemented — and they have had a staggering effectiveness rate of around 90 per cent.
World Aids Day highlights urgency of global epidemic
An estimated 34.2 million people worldwide live with HIV, a statistic the World Health Organization hopes hit home during World Aids Day on December 1, a day meant to raise awareness about this global epidemic. The latest report released from UNAIDS contains encouraging numbers showing significant decrease in new HIV infections especially in Africa where the global effort to provide wide scale treatment is starting to show results. For latest information on UNAIDS report see http://www.unaids.org/en/
At McMaster, Charu Kaushic and Ken Rosenthal, members of the Michael G. DeGroote Institute for Infectious Disease Research (IIDR) and professors in the Department of Pathology and Molecular Medicine, have taken great strides in understanding HIV/AIDS.
Bowdish lab elucidates evolution of the class A scavenger receptors
Fiona Whelan, a Master's student in Dawn Bowdish's lab, has published her first manuscript “The Evolution of the class A scavenger receptors” in BMC Evolutionary Biology. The goal of the manuscript was to use evolution as a guide to discover how the class A scavenger receptor family was formed and to identify regions of conservation and hence probable functional importance for future study.
He would sometimes trek over 30 kilometers a day through mountainous terrain, inclement weather and on muddy footpaths, to find the answer to one simple question: “Was barium in wild mushrooms the cause of more than 400 unexplained deaths throughout southwest China over the past 30 years?”
The journey was so treacherous it once sent one of his co-travellers to hospital with fatigue and dehydration. But the answer McMaster biologist Jianping Xu found shatters a myth started in 2010 from a news article in the journal Science, that claimed the Trogia venenata mushroom contained high concentrations of the metal barium, causing high blood pressure, cardiac arrests and sudden deaths. The deaths mainly occurred in small villages, some of which saw nearly one-third of their population perish quickly and within very short periods of time.
Probiotics show potential to minimize C. difficile
New cases of C. difficile-associated diarrhea among hospitalized patients taking antibiotics can be reduced by two-thirds with the use of probiotics, according to new research published Monday in the Annals of Internal Medicine.
“Probiotics are not a magic bullet, but these results suggest therapeutic probiotic agents, as well as some yogurts and probiotic dairy products, may be vastly under-used in some nursing homes and hospitals,” says lead author Bradley Johnston, assistant professor in the Department of Clinical Epidemiology and Biostatistics, and a scientist and clinical epidemiologist at SickKids Hospital in Toronto.
IIDR member Mark Loeb, professor of Pathology and Molecular Medicine in the Michael G. DeGroote School of Medicine, and division director of Infectious Diseases, was co-author on the study.
Using the High Throughput Screening Lab (HTS) in the Centre for Microbial Chemical Biology (CMCB), Canadian researchers are opening new doors to the understanding of antibiotic resistance.
Two recent discoveries, published in Chemistry & Biology, provides promise in treating infections in an age of increasing antibiotic resistance. The first involved Justin Nodwell, member of the Michael G. DeGroote Institute for Infectious Disease Research (IIDR) and Associate Chair, Graduate Education, Biochemistry & Biomedical Sciences, and the second, former McMaster professor Christian Baron, now Professor and Chair at the University of Montreal.
The old adage “if you can’t beat ‘em, join ‘em” is ringing true in an age where antibiotic resistance is rampant.
Justin Nodwell’s lab has discovered that it’s not always best to fight resistance, but embrace it. His lab has revealed that by manipulating a two-step process in the biosynthesis of bacteria, it is possible to control microbial infections clinically, a finding that provides an understanding as to how and when resistance in bacteria is activated.
Study presents possibilities for drug detoxification in chemotherapy patients
Researchers with the Michael G. DeGroote Institute for Infectious Disease Research (IIDR) have made a promising discovery that puts them one step closer to curbing the side effects of chemotherapy treatment in cancer patients.
A new study, published in Chemistry & Biology, has found that non-producer soil bacteria can harbor the biological machinery required to degrade and inactivate anticancer therapeutics.
Terry Fox Foundation gives McMaster researchers $2 million
About $2 million raised from Terry Fox runs is going directly to McMaster researchers trying to harness the power of viruses to kill tumors.
The Terry Fox Foundation gave out $13.4 million to two national research teams – one studying ways to treat acute leukemias and the other researching the ability of oncolytic viruses to kill cancer cells while leaving healthy ones unharmed.
McMaster’s Brian Lichty, Jonathan Bramson and Karen Mossman (members of the Michael G. DeGroote Institute for Infectious Disease Research) and Yonghong Wan are part of the Canadian Oncolytic Virus Consortium led by the Ottawa Hospital Research Institute getting $7.5 million of that funding over five years.
Bramson’s team will get $992,000 and Lichty’s team’s share is $950,000.
Chad Johnston felt inspired as he sat in on Michael Hart’s lecture three years ago. Hart, a second-year Master’s student in Justin Nodwell’s lab was discussing his work exploring the use of environmental microbes as sources of biologically active drug leads, an area very close to Johnston’s own research heart.
At the time, Johnston was completing his undergraduate degree at McMaster. Sadly, the next year, Hart passed away from B cell lymphoma, but through a newly established scholarship created in his memory, Johnston is carrying on a similar research quest.
Gerry Wright, scientific director of the Michael G. DeGroote Institute for Infectious Disease Research, has been elected a fellow of the Royal Society of Canada. The designation is considered the country’s highest honour for a scholar in the arts, humanities or sciences.
Wright, a professor of the Department of Biochemistry and Biomedical Sciences, joins a second McMaster recipient, Gordon Guyatt, a physician and Distinguished University Professor of the Department of Clinical Epidemiology and Biostatistics.
By night he belts out Motown on his sax on the Hamilton music scene; by day he screens for inhibitors of NDM-1 in the Wright lab.
Andrew King, a first-year PhD student in the lab of Gerry Wright, scientific director of the Michael G. DeGroote Institute for Infectious Disease Research, is adept at both.

The new provincial investment matches federal awards from the Canada Foundation for Innovation over the last year. Ted McMeekin, Minister of Agriculture, Food and Rural Affairs, made the announcement during a visit to McMaster’s campus on Wednesday.
MIRC partners with Biocells Biotech to develop cancer immunotherapy in China
Delegates from the McMaster Immunology Research Centre (Drs. Jonathan Bramson, Jack Gauldie and Yonghong Wan) recently traveled to Beijing and Taiyuan, China for a series of meetings to discuss partnerships to develop cancer immunotherapies in China. These meetings culminated with the signing of a memorandum of understanding that identified Biocells Biotech as MIRC's preferred partner in China. Together, MIRC scientists and Biocells scientists will work to improve Biocells' cancer therapies, including cytokine-induced killer cells and dendritic cells vaccines. Future goals aim to translate novel technologies being developed at MIRC to the Chinese market.
Two McMaster students have been given a confidence boost in their research programs after receiving Master’s Awards from the Canadian Institutes for Health Research.
Not only did Amanda Lee, a first-year Master’s student in Pathology and Molecular Medicine, and Jon Stokes, a PhD candidate in Biochemistry, receive the awards that recognize students with an exceptionally high potential for future research achievement and productivity, they were ranked first and third, respectively, of 135 successful applicants across the country.
Jason Fan grew up at McMaster. As a young child he would come with his father Boguang Fan to McMaster and watch him work in the labs of the Faculty of Health Science’s Gastrointestinal Program. At age three, a passion for science had sparked.
Today, the Grade 11 student from Westdale Secondary School in Hamilton, and winner of the 2012 winner of the Michael G. DeGroote Institute for Infectious Disease Research Bay Area Science and Engineering Fair (BASEF) Research Award, is working alongside researchers learning some of the most innovative techniques in science.
When it comes to the immune system, it’s all about balance. Natural killer cells are important early responders to infection. In the case of influenza, while initially beneficial, these cells can cause damage to the lung if they are active for a prolonged period of time.
If you ask what makes her passionate, you may be surprised by the answer. “Soil-dwelling micro-organisms,” she smiles, convincingly.
Because of it, Canada’s future industrial and commercial growth looks promising, which is why McMaster PhD candidate Renée St-Onge, a student in IIDR member Marie Elliot’s lab, is most excited to receive a prestigious 2012 Vanier Canada Graduate Scholarship. “More than anything, being awarded the Vanier Canada Graduate Scholarship is a tremendous honour and an unparalleled opportunity,” she says. “It will permit me to pursue my passion while contributing to our country’s industrial and economic growth.”
Five scientists with the McMaster Immunology Research Centre (MIRC) have been awarded $3 million in direct research funding from the Canadian Institutes for Health Research.
Recipients receiving the operating grants include Ali Ashkar, Dawn Bowdish, Charu Kaushic, Karen Mossman, and Yonghong Wan, all from the Department of Pathology and Molecular Medicine. Ashkar, Bowdish, Kaushic and Mossman are also members of the Michael G. DeGroote Institute for Infectious Disease Research.
Jianping Xu, a member of the Michael G. DeGroote Institute for Infectious Disease Research and Professor in the Department of Biology, received a best poster award at the 18th Congress of the International Society for Human and Animal Mycology, which took place recently in Berlin, Germany. The poster, that demonstrated a unique approach to one of world's most common nail infections, was among 12 posters recognized from more than 700 presentations .
You may be inclined to call her a scientist, but McMaster PhD student Marisa Azad, winner of a 2012 Vanier Canada Graduate Scholarship, considers herself an artist. Whether she is home brushing strokes of paint on a canvas or in the lab synthesizing anti-microbial peptides, she is “creating art; making something magical from scratch.”
It’s a sweep for McMaster University microbiologists as winners of the two top career awards presented annually by the Canadian Society of Microbiologists.

Whelan, who studies medical science in IIDR member Dawn Bowdish's lab, is one of only 70 women around the globe and just five in Canada to be awarded the scholarship.
Zinc may shorten colds for adults, but not for kids
An analysis of 17 patient trials comparing oral zinc preparations to placebo found that sucking on the lozenges appeared to shorten the duration of the common cold by about two days. But lead author Dr. Michelle Science, an infectious disease specialist at Toronto's Hospital for Sick Children, and graduate student of Mark Loeb, coauthor and member of the Institute for Infectious Disease Research, said the review of the trials involving more than 2,100 patients did not show that using zinc alleviated the severity of symptoms. IIDR member Jennie Johnston was also a coathor of the study.

Antibiotic resistance flourishes in freshwater systems
The author Dr. Seuss may have been on to something when he imagined that microscopic communities could live and flourish on small specs of dust, barely visible to the naked eye. In fact, such vibrant communities exist – in a material with a Seussical sounding, yet scientific name called 'floc'.
McMaster University researchers have now discovered that floc – "goo-like" substances that occur suspended in water and that host large communities of bacteria – also contain high levels of antibiotic resistance.
The research was led by Lesley Warren, professor of Earth Sciences and Gerry Wright, scientific director of the Michael G. DeGroote Institute for Infectious Disease Research, both of McMaster, along with Ian Droppo, a research scientist at Environment Canada.
Charu Kaushic, an associate professor in Department of Pathology and Molecular Medicine, has been awarded an Applied HIV Research Chair from the Ontario HIV Treatment Network (OHTN), to study heterosexual transmission of HIV in women and the impact of hormonal contraceptives use on HIV susceptibility.
McMaster University and University of Akron researchers are leading the way in understanding the origins of antibiotic resistance, a global challenge that is creating a serious threat to the treatment of infectious diseases.
Gerry Wright, scientific director of the Michael G. DeGroote Institute for Infectious Disease Research (IIDR) at McMaster University, and Hazel Barton, assistant professor of biology at the University of Akron, discovered a remarkable prevalence of antibiotic resistance bacteria isolated from Lechuguilla Cave in New Mexico one of the deepest and largest caves in the world and a place isolated from human contact for more than four million years.
The research was published today (April 11, 2012) in the Journal PLoS ONE.
Infectious disease expert to present Perey Lecture
Adrian Hill, an internationally recognized infectious disease expert from the University of Oxford, will present the 27th D.Y.E. Perey Lecture, the Faculty of Health Science’s oldest, fully-endowed premier lecture.
Titled, “Tropical infectious diseases: from innate immunity to candidate vaccines,” Dr. Hill’s talk will take place on Wednesday, April 25 from 9-10 a.m. in the Health Sciences Centre Rm. 1A1.
An international team of scientists have created an innovative tool for teaching the fundamentals of epidemiology—the science of how infectious diseases move through a population.
The team teaches a workshop annually in South Africa that helps epidemiologists improve the mathematical models they use to study outbreaks of diseases like cholera, AIDS and malaria. The team created a new game as a teaching aid for the workshop and which has proven effective in demonstrating concepts of epidemiology. The game was conceived by Steve Bellan of UC Berkeley and Juliet Pulliam of U. Florida, and implemented by a team of researchers, including Jonathan Dushoff, an associate professor of biology at McMaster and member of the M.G. DeGroote Institute for Infectious Disease Research, and James Scott of Colby College; all four co-authored the paper.
The Michael G. DeGroote Institute for Infectious Disease Research (IIDR) recognized young scientists with an eye for the innovative during the recent Bay Area Science and Engineering Fair.
Jason Fan, a Grade 11 student from Westdale Secondary School in Hamilton, was the first place winner of the IIDR prize that recognized the best senior project in infectious disease, drug discovery or human health. Fan’s project involved testing ligustrazine, a drug derived from traditional Chinese medicine. He examined if ligustrazine would be a valuable therapeutic for Alzheimer's disease by protecting neurons from cell death caused by oxidative stress. He performed his research under the guidance of Dr. Margaret Fahnestock, Professor, Psychiatry & Behavioural Neurosciences at McMaster University.

Tuberculosis (TB) infects one-third of the world’s population, making it one of the most devastating infectious diseases.
On World TB Day March 24, McMaster’s infectious disease experts will join the world in emphasizing the urgent need for international TB vaccine development. Established by the World Health Organization, the day commemorates when Robert Koch announced 1882 that he had discovered the cause of tuberculosis, the TB bacillus. At the time of Koch's announcement in Berlin, TB was raging through Europe and the Americas, causing the death of one out of every seven people. Koch's discovery opened the way towards diagnosing and curing TB.

School closures stop spread of H1N1
Closing elementary and secondary schools can help slow the spread of infectious disease and should be considered as a control measure during pandemic outbreaks, according to a McMaster University led study.
Using high-quality data about the incidence of influenza infections in Alberta during the 2009 H1N1 flu pandemic, the researchers show that when schools closed for the summer, the transmission of infection from person to person was sharply reduced.
“Our study demonstrates that school-age children were important drivers of pH1N1 transmission in 2009,” says David Earn, lead author of the study published in Annals of Internal Medicine. Earn is professor in the Department of Mathematics and Statistics and member of McMaster’s Michael G. DeGroote Institute for Infectious Disease Research (IIDR).
Microbial genomics as a strategy for developing antimicrobial drugs "failed to deliver" in part because "we don't understand the biology," says Eric Brown, Professor and Chair of Biochemistry and Biomedical Sciences and member of McMaster's Michael G. DeGroote Insitute for Infectious Disease Research. His strategy to overcome that impasse involves using antibiotics to "probe biology" and thus learn more about "essential functions" of microbes en route, perhaps, to novel or improved antimicrobials. He spoke during the symposium, "A New World of Academic Antimicrobial Discovery," part of the Interscience Conference on Antimicrobial Agents and Chemotherapy, held in Chicago, Ill., last September.
Drugs used to overcome cancer can also combat antibiotic resistance, finds a new study led by Gerry Wright, scientific director of the Michael G. DeGroote Institute for Infectious Disease Research.
“Our study found that certain proteins, called kinases, that confer antibiotic resistance are structurally related to proteins important in cancer,” says Wright about the study published in Chemistry & Biology.
IIDR members and trainees are invited to an upcoming SWOP meeting on Saturday, May 31st at the University of Guelph. For more information view the poster.
