The frequency of methicillin-resistant Staphylococcus aureus (MRSA) has increased in the community. This study evaluated the prevalence of MRSA and community-acquired (CA)-MRSA in 120 healthy elderly. The MRSA were evaluated for the presence of the IS256, mecA, agr, icaA, icaD, fnbB , and pvl genes with PCR. Frequency of S. aureus and MRSA colonization was 17.8% and 19%, respectively. CA-MRSA isolate showed SCC mec IV, fnbB+ , and icaD+ . CA-MRSA was detected, with genotype determined as SCC mec type IV/IS256/ fnbB+ / icaA / icaD+ / bbp-/agr2 / bap / pvl, characterizing this population as a possible reservoir of this organism in the community.
