Staphylococcus aureus was isolated from an individual with acne. The isolate was Gram positive, spherical and in clusters, golden yellow on mannitol salt agar and non spore forming. Biochemical tests showed that it was unable to hydrolyze gelatin but able to ferment glucose, galactose and mannitol. It produced catalase and coagulase enzymes. It was able to utilize citrate as sole carbon source but was indole negative. It was Methyl Red positive and Voges-Proskauer negative. It was sensitive to gentamicin, tetracycline, amoxicillin, augmentin, chloramphenicol and sulphamethoxazole but resistant to ampicillin, erythromycin, cloxacillin, cotrimoxazole, streptomycin and penicillin.
Key words: Antibiotics, resistance, susceptibility, acne, Staphylococcus aureus.
