*MRSA, methicillin-resistant Staphylococcus aureus; PB, penicillin-binding region;;MLST, multilocus sequence typing; R, resistant; S,
susceptible; TMP-SMX, trimethoprim-sulfamethoxazole.
†All isolates were associated with mecA and ccr2 genes.
‡Phenotype: as defined by the study case definition, according to antimicrobial drug susceptibilities (see Methods).
