[pyomyositis]

We studied 12 Staphylococcus aureus isolates causing tropical pyomyositis in the Amazon Basin of Peru . All isolates were methicillin-susceptible ; 11 carried Panton -Valentine leukocidin-encoding genes , and 5 belonged to multilocus sequence type 25 and possessed an extensive set of enterotoxins . Our findings suggest sequence type 25 is circulating in tropical areas of South America .
