Chemicals used in the environment to kill bacteria could be making them stronger, according to a paper published in the October issue of the journal Microbiology. Low levels of these chemicals, called biocides, can make the potentially lethal bacterium Staphylococcus aureus remove toxic chemicals from the cell even more efficiently, potentially making it resistant to being killed by some antibiotics.

Many nursing mothers who have been hospitalized for breast abscesses are afflicted with the "superbug" methicillin-resistant Staphylococcus aureus, or MRSA, but according to new research by UT Southwestern Medical Center physicians, conservative treatment can deal with the problem.

Recent tabloid hype over the "newly emerging superbug", Stenotrophomonas maltophilia, is misplaced, say experts in this week's issue of the BMJ.

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain—USA300—of an evolving bacterium that has spread with “extraordinary transmissibility” throughout the United States during the past five years, according to a new study led by National Institutes of Health (NIH) scientists.

University of Idaho researchers are crossing academic and geographical bounds to develop more effective defenses against Staphylococcus aureus bacteria and other deadly pathogens.

Researchers from Italy have identified a bacteriophage active against Staphylococcus aureus, including methicillin-resistant strains, in mice and possibly humans. They report their findings in the August 2007 issue of the journal Antimicrobial Agents and Chemotherapy.

Researchers at UCLA have developed a mathematical model that mimics a particularly nasty and ongoing outbreak in the Los Angeles County Jail (LACJ) of the flesh eating bacteria Staphylococcus Aureus.

The U.S. Food and Drug Administration gave an approval to GlaxoSmithKline PLC said to market a new treatment for a skin infection children usually suffer from.
