Antibiotic Resistance

A self-cleaning surface that repels even the deadliest superbugs

A team of researchers at McMaster University has developed a self-cleaning surface that can repel all forms of bacteria, preventing the transfer of antibiotic-resistant superbugs and other dangerous bacteria in settings ranging from hospitals to kitchens. The new plastic surface — a treated form of conventional transparent wrap – can be shrink-wrapped onto door handles, railings, IV stands and other ...

Antibiotic-resistant bacteria more prevalent in device-related Infections

DetailsMonday, 25 November 2019 Healthcare-associated infections (HAIs) related to the use of medical devices are more likely to be antibiotic resistant than HAIs that result from surgical procedures, according to a report from the Centers for Disease Control and Prevention’s (CDC’s) National Healthcare Safety Network (NHSN) published today in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare ...

Impacts of low-dose exposure to antibiotics unveiled in zebrafish gut

The study, published this week in the Proceedings of the National Academy of Sciences, applied three-dimensional microscopy to nearly transparent zebrafish to show how weak levels of antibiotics induce structural changes in gut bacterial communities that cause severe drops in the bacterial populations. “Low levels of antibiotics are often found as environmental contaminants, for example from widespread use in raising livestock,” ...

80% cut in antibiotics entering Thames is needed to avoid surge in superbugs

The amount of antibiotics entering the River Thames would need to be cut by as much as 80% to avoid the development and spread of antibiotic-resistant “superbugs,” a new study has shown. Scientists from the Centre for Ecology and Hydrology (CEH) modeled the effects of antibiotic prescriptions on the development of antibiotic-resistant bacteria in a river. It found that across ...

New compound that kills antibiotic-resistant superbugs discovered

A new compound which visualizes and kills antibiotic resistant superbugs has been discovered by scientists at the University of Sheffield and Rutherford Appleton Laboratory (RAL). The team, led by Professor Jim Thomas, from the University of Sheffield’s Department of Chemistry, is testing new compounds developed by his PhD student Kirsty Smitten on antibiotic resistant gram-negative bacteria, including pathogenic E. coli. Gram-negative ...
