"Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has recently emerged worldwide. The United States, in particular, is experiencing a serious epidemic of CA-MRSA that is almost entirely caused by an extraordinarily infectious strain named USA300," scientists in Shanghai, People's Republic of China report. "However, the molecular determinants underlying the pathogenic success of CA-MRSA are mostly unknown.

We discovered that the sublineage from which USA300 evolved...
