The nares as a CA-MRSA reservoir in the healthy elderly

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract:

INTRODUCTION:

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.

METHODS:

The MRSA were evaluated for the presence of the IS256, mecA, agr, icaA, icaD, fnbB , and pvl genes with PCR. Results: Frequency of S. aureus and MRSA colonization was 17.8% and 19%, respectively. CA-MRSA isolate showed SCC mec IV, fnbB + , and icaD + .

CONCLUSIONS:

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.
