Staphylococcus aureus is part of the normal flora of the skin and mucous membranes, with the nostrils the primary reservoir. Patients with HIV/AIDS, carriers of S. aureus, are more likely to develop infections due to this organism. The aim was to determine the nasal carriage of S. aureus in children who come for outpatient consultation at the INNOCENS Foundation and its resistance to methicillin and erythromycin, using a prospective descriptive study. During the months February-April 2013, 38 nasal secretion samples were analyzed. The samples were inoculated onto blood agar plates and colonies compatible with Staphylococcus spp. were identified, including their species. In the S. aureus strains, resistance to oxacillin was detected by the disk diffusion method, a screening test (agar supplemented with 6 ug/mL of oxacillin and 4% sodium chloride) and Minimum Inhibitory Concentration. Of the 38 children with HIV, 17 (44.7 %) carried S. aureus in their nostrils. Of these, 3 were resistant to methicillin and 8 (47.1%) were resistant to erythromycin. Nasal carriage of S. aureus in children with HIV is a serious problem because it can further compromise their health.Staphylococcus aureus is part of the normal flora of the skin and mucous membranes, withthe nostrils the primary reservoir.
