The bacterial scourge methicillin-resistant Staphylococcus aureus (MRSA) can cause life-threatening infections that are difficult to beat with antibiotics. Earlier this year, hospitals in France reported a decline in the rates of the infections after 15 years of concerted control efforts, and ongoing analyses from the U.K. have shown decreasing incidence as well. A new study from the U.S. Centers for Disease Control and Prevention (CDC) reports the number of health care-related MRSA bloodstream infections in nine cities across the country dropped substantially between 2005 and 2008.

Although S. aureus lives in relative biotic harmony on about a third of all people, its drug-resistant varieties can evolve rapidly and spread easily in both health care and, more recently, community settings.
