Trained Viruses Prove More Effective at Fighting Antibiotic Resistance
University of California San Diego

Research reveals that phage viruses that undergo special evolutionary training increase their capacity to subdue bacteria. The results provide hope for the antibiotic resistance crisis, a rising threat as deadly bacteria continue to evolve to render many modern drugs ineffective.

Global travelers pick up numerous genes that promote microbial resistance
Washington University in St. Louis

Research from Washington University School of Medicine in St. Louis shows that international travelers often return home with new bacterial strains jostling for position among the thousands that normally reside within the gut microbiome. Such travel is contributing to the rapid global increase and spread of antimicrobial resistance.

Diphtheria risks becoming major global threat again as it evolves antimicrobial resistance
University of Cambridge

Diphtheria - a relatively easily-preventable infection - is evolving to become resistant to a number of classes of antibiotics and in future could lead to vaccine escape, warn an international team of researchers from the UK and India.

Antibiotic tolerance study paves way for new treatments
Cornell University

The study in mice, “A Multifaceted Cellular Damage Repair and Prevention Pathway Promotes High Level Tolerance to Beta-lactam Antibiotics,” published Feb. 3 in the journal EMBO Reports, reveals how tolerance occurs, thanks to a system that mitigates iron toxicity in bacteria that have been exposed to penicillin.

Older adults and antibiotics: Study shows healthy attitudes but unhealthy practices
Michigan Medicine - University of Michigan

While most adults over 50 understand that overuse of antibiotics is a problem, and say they’re cautious about taking the drugs, a sizable minority have used antibiotics for something other than their original purpose, and appear to think the drugs could help treat colds, which are caused by viruses not bacteria.

Grant to help fill gaps in how livestock manure management affects antibiotic resistance
Iowa State University

Iowa State University researchers received a $1 million grant to study how manure management systems in livestock production may give rise to antibiotic resistance. Human, animal and environmental health interact in complex ways that influence the pace at which antibiotic resistance spreads, and the researchers hope their work will shed light on these connections.

UTEP Fights Superbugs with $1.2 Million NIH Grant to Develop a New Way to Produce Antibiotics
University of Texas at El Paso

Chu-Young Kim, Ph.D., associate professor of chemistry and biochemistry at The University of Texas at El Paso, is helping combat the threat of superbugs – illnesses caused by drug-resistant bacteria – by returning to nature. His work is supported by a $1.2 million grant from the National Institutes of Health (NIH) to develop a biological method for producing new versions of current antibiotics that have become ineffective due to resistance

Livestock workers face high MRSA risk
Michigan State University

For Michigan State University’s Felicia Wu, the surprise isn’t that people who work with livestock are at higher risk of picking up antibiotic-resistant bacteria, but instead how much higher their risk levels are. “This is a bit of a wakeup call,” said Wu, John. A Hannah Distinguished Professor in the Departments of Food Science and Human Nutrition and Agricultural, Food and Resource Economics. “I don’t think there was much awareness that swine workers are at such high risk, for example. Or that large animal vets are also at extremely high risk.”

New Vaccine Development Platform Could Fight Deadly, Multi-Drug Resistant Bacteria
Uniformed Services University of the Health Sciences (USU)

A new vaccine development platform has proven effective in protecting against deadly, hard-to-treat infections caused by multi-drug resistant (MDR) bacteria, thanks to a collaborative endeavor led by Dr. Michael J. Daly, a professor in the Uniformed Services University's (USU) Department of Pathology, Dr. Gregory J. Tobin, president of Biological Mimetics, Inc., and Dr. Daniel Zurawski at the Walter Reed Army Institute of Research. This could ultimately help prevent battlefield infections, as well as common hospital-acquired infections in patients undergoing routine surgeries.

Antibiotic resistance may spread even more easily than expected
Chalmers University of Technology

Pathogenic bacteria in humans are developing resistance to antibiotics much faster than expected. Now, computational research at Chalmers University of Technology, Sweden, shows that one reason could be significant genetic transfer between bacteria in our ecosystems and to humans. This work has also led to new tools for resistance researchers.
