To determine the prevalence of nasal colonization of S Staphylococcus aureus, its antimicrobial sensitivity profile, methicillin-resistance in strains isolated and the relation between carrier state, immunological status and use of antimicrobials in a group of patients infected with human immunodeficiency virus (HIV) in Medellin.

151 nasal samples were obtained from ambulatory patients with HIV. Antimicrobial sensitivity profile of S. aureus isolates were evaluated using the Kirby-Bauer method. In addition, we also determined minimum inhibitory concentrations (MIC) for oxacillin and vancomycin. Presence of the mecA gene in methicillin-resistant S. aureus isolates (MRSA) was confirmed through polymerase chain reaction.

Staphylococcus aureus, methicillin resistance, colonization, human immunodeficience virus and PCR.
