Prevalence and Antibiotic Susceptibility Pattern of Staphylococcus Aureus in Clinical Specimens

Abstract

The present study was carried out to determine the prevalence of Staphylococcus aureus in clinical samples and their susceptibility pattern to antibiotics. Standard microbiological and biochemical methods were used to screen 155 clinical specimens comprising of sputum, wound, urine and high vaginal swabs for S .aureus. Twenty eight (28) isolates was obtained from these samples. Antibiotic susceptibility results shows high percentage of sensitivity to gentamicin (89%,) azithromycin (89%), pefloxacin (79%)  followed by erythromycin (68%) ciprofloxacin (61%) streptomycin (61%)and sparfloxacin (54%). A high resistance was recorded for cotrimaxazole (90%), amoxycillin (88%), ampicillin (73%), tetracycline (65%), cefuroxime and cephalexin (40%) each.

Key words: Staphylococcus aureus, antibiotic susceptibility, prevalence, resistance.
