UK newspapers tend to report infectious disease news trends faster than US papers. The Times Online reports a "playground superbug" which turns out to be a strain of MRSA that produces a toxin Panton-Valentine leukocidin (PVL). Apparently this type of MRSA more easily infects the bone, where it's hard for drug to reach and kill the infection. It does not seem like this type of MRSA is very common, but watch for MRSA-PVL to be making headlines in the US soon.
