Abstract

Recent reports have described an increasing incidence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in patients who do not exhibit established risk factors for healthcare exposure. We report two cases of CA-MRSA bacteremia complicated by vertebral osteomyelitis. Both of CA-MRSA isolates were resistant to beta-lactam agents, but susceptible to clindamycin, trimethoprim-sulfamethoxazole, gentamicin, ciprofloxacin, and tetracycline. Both isolates carried staphylococcal cassette chromosome mec (SCCmec) type IVA, and were identified as sequence type (ST) 72 by mlultilocus sequence typing (MLST). However, the Panton-Valentine leukocidin (PVL) gene was not identified.
