Detection and analysis of methicillinresistant human-adapted sequence type 398 allows insight into communityassociated methicillin-resistant Staphylococcus aureus evolution

Severe infections with highly virulent community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) are a global problem. However, the molecular events defining the evolution of CA-MRSA are still poorly understood.
