Community-associated methicillin-resistant staphylococcus aureus epidemic clone USA100; more than a nosocomial pathogen

BACKGROUND: We characterized 100 USA100 epidemic MRSA from individuals in the community with no known healthcare-associated risk factors. FINDINGS: Molecular epidemiology demonstrated 21 pulsed-field types and six spa types. SCCmec typing demonstrated that all of the strains possess the type II cass...

Sumario:BACKGROUND: We characterized 100 USA100 epidemic MRSA from individuals in the community with no known healthcare-associated risk factors. FINDINGS: Molecular epidemiology demonstrated 21 pulsed-field types and six spa types. SCCmec typing demonstrated that all of the strains possess the type II cassette. The staphylococcal enterotoxin D virulence gene was also present. CONCLUSION: Characterization of USA100 MRSA in the community illustrated the importance of nasal carriage, and the genetic diversity of the USA100 clone.
