Antibiotic resistance—it's a social thing

Trace concentrations of antibiotic, such as those found in sewage outfalls, are enough to enable bacteria to keep antibiotic resistance, new research from the University of York has found. The concentrations are much lower ...

High penicillin prescribing could build reservoirs of resistance

(HealthDay)—High penicillin G prescribing may lead to an altered level of resistance in the commensal viridans group streptococci (VGS) population, which may be important in subsequent horizontal gene transfer events, according ...

Scientists target bacterial transfer of resistance genes

The bacterium Streptococcus pneumoniae – which can cause pneumonia, meningitis, bacteremia and sepsis – likes to share its antibiotic-defeating weaponry with its neighbors. Individual cells can pass resistance genes to ...

Scientists link quickly spreading gene to Asian MRSA epidemic

National Institutes of Health (NIH) scientists and their colleagues in China have described a rapidly emerging Staphylococcus aureus gene, called sasX, which plays a pivotal role in establishing methicillin-resistant S. aureus ...
