The antimicrobial sensitivity pattern of bacterial isolates from suspected urinary tract infection (UTI) patients at Igbinedion University Teaching Hospital was carried out from November 2004 to November 2005 using the disc diffusion method. The subjects were made up of 330 (60%) males and 220 (40%) females. The commonest isolates were Escherichia coli (51.2%), Staphylococcus aureus (27.3%), and Klebsiella pneumoniae (12.8%) respectively. Both methicillin-resistant (MRSA) and methicillin sensitive (MSSA) S. aureus were isolated in the study. The isolates were highly sensitive to ofloxacin but low to moderately sensitive to gentimicin, tobramycin, nalidixic acid, ciprofloxacin, tetracycline, nitrofurantoin, and cefuroxine. The MSSA isolates were highly sensitive to ciprofloxaxin and ofloxacin while the MRSA were sensitive to ofloxacin. In addition, the isolates showed multi-drug resistance.
Key words: Bacterial resistance, b-lactamases, methicillin-resistant Staphylococcus aureus (MRSA), methicillin sensitive (MSSA) S. aureus.
