Molecular characterization of selected nasal isolates of methicillin-resistant Staphylococcus aureus (MRSA) from healthy students of a tertiary institution

Purpose: To investigate the incidence of methicillin-resistant Staphylococcus aureus (MRSA) and carry out molecular characterization in selected nasal isolates from healthy students Abraka, Nigeria.Methods: Three hundred (300) samples were obtained apparently 150 female male cultured suitable media for identification. The MRSA detected by means oxacillin antibiotic sensitivity disk. Antibiotics susceptibility pattern was carried accordance with guidelines Clinical Laboratory Standard Institute. Tests to determine presence penicillin binding protein2a (PBP2a). Molecular twenty (20) representatives done establish existence mecA genes among isolates.Results: colonization amongst community 68 (22.7 %). was: amoxicillin, 40 (58.8 %); amoxicillin/clavulanate, 15 (22.1 chloramphenicol, ciprofloxacin, 19 (27.9 co-trimoxazole, 9 (13.2 gentamicin, ofloxacin, 8 (11.1 streptomycin, 30 (44.1 All subjected possessed (PBP2a) while only one gene.Conclusion: is present individuals Delta State. It also possible not detect gene even when present. Since most are multi-drug resistant, there a tendency clinical therapy failure this area.
