Global epidemiology of community-associated methicillin resistant Staphylococcus aureus (CA-MRSA)

► Numerous CA-MRSA lineages have been described in the last two decades. ► Several of these may be considered pandemic, particularly USA300. ► We highlight the molecular epidemiology of CA-MRSA clones at the present time. ► The close association between CA-MRSA and PVL remains controversial. ► CA-MRSA clones are increasingly causing healthcare-associated infections worldwide.
