With drug-resistant bacteria on the rise, even common infections that were easily controlled for decades -- such as pneumonia or urinary tract infections -- are proving trickier to treat with standard antibiotics. New drugs are desperately needed, but so are ways to maximize the effective lifespan of these drugs. To accomplish that, Duke University researchers used software they developed to predict a constantly-evolving infectious bacterium's countermoves to one of these new drugs ahead of time, before the drug is even tested on patients.

New research findings point toward a class of compounds that could be effective in combating infections caused by enterovirus D68, which has stricken children with serious respiratory infections and might be associated with polio-like symptoms in the United States and elsewhere.

Cholera is caused when the bacterium Vibrio cholerae infects the small intestine. The disease is characterized by acute watery diarrhea resulting in severe dehydration. EPFL scientists have now demonstrated that V. cholerae uses a tiny spear to stab and kill neighboring bacteria -- even of its own kind -- and then steal their DNA. This mechanism, known as "horizontal gene transfer," allows the cholera bacterium to become more virulent by absorbing the traits of its prey. The study is published in the journal Science.

If having limited resources at your healthcare institution is forcing you to choose one key infection control-related intervention -- either hand hygiene or environmental hygiene -- to get the most return on investment, what would you select? Researchers have developed a model that can help infection preventionists, healthcare epidemiologists and administrators determine which strategies have a better pay-off from a patient safety perspective and can help guide resource-allocation decisions.

One of the most talked-about issues at last year's IDWeek conference was patient bathing with chlorhexidine gluconate (CHG). The topic was included in a session called "Thorny Issues in Infection Prevention" in which panelists described practical solutions to real-world problems in infection prevention, compared the strengths and weaknesses of the solutions discussed, and debated strategies to assist in the implementation of the solutions presented. Moderated by Charles Huskins, MD, MSc, FIDSA, FSHEA, FPIDS, of Mayo Clinic and Thomas Talbot, MD, MPH, of Vanderbilt University, the panel included Loreen Herwaldt, MD, FIDSA, FSHEA; Susan Ray, MD, FIDSA; Stephen Parodi, MD, FIDSA; Edward Septimus, MD, FIDSA, FSHEA; and Danielle Zerr, MD, MPH, FPIDS. 

This is a story about nursing education – both academic and clinical. It’s a powerful example of how one can impact the other, and how both can lead to a new evidence-based best practice that benefits patients and their providers. It’s also about nursing compassion, and a willingness to change a culture in order to prevent patient suffering.

An international research team has shown how changes in a flu virus that has plagued Chinese poultry farms for decades helped create the novel avian H7N9 influenza A virus that has sickened more than 375 people since 2013. The research appears in the current online early edition of the scientific journal Proceedings of the National Academy of Sciences.
