The often feared and sometimes deadly infections caused by MRSA -- methicillin-resistant Staphylococcus aureus -- are now moving out of hospitals and emerging as an even more virulent strain in community settings and on athletic teams, and raising new concerns about antibiotic resistance.
Right now, the new community-associated strain of MRSA is responsive to more, but sometimes different antibiotics than its hospital relative, experts say. But those antibiotics will almost certainly lose their effectiveness as they are used more widely, and efforts are under way to combat that issue.
