STAPHYLOCOCCUS AUREUS ASSOCIATED WITH ENVIRONMENTAL FOMITE AT ILE-IFE, OSUN STATE NIGERIA

Abstract

Introduction: Staphylococcus aureus is a pathogenic microorganism responsible for mild to life threatening infections. Fomites are being increasingly recognized as a significant means of transmission of Staphylococcus aureus infections. Therefore, this study determines the possible roles of cross contamination in the community environment.

Methods: A total of 50 fomite samples were obtained, 10 each from ATM key boards, Door knobs, Commercial bus steering wheel, Students’ hand phones and Iron Rails in Obafemi Awolowo University’s academic area. Selected fomites were sampled using a cotton swab technique. Isolates were identified as S. aureus using their morphological characteristics on mannitol salt agar and biochemical characteristics

Result: A total of 19 (38%) Staphylococcus aureus isolates was recovered from the 50 samples collected – 40% from ATM key boards, 30% from Door knobs, 40% from Commercial bus steering wheel, 20% from Iron Rails and 60% from Students’ hand phones. The isolates were susceptible to Streptomycin (100%), Cotrimoxazole [Septrin] (74%), Ciprofloxacin 79% and Gentamicin 63% but resistant to Ampiclox [Ampicillin and Cloxacillin] (100%) and Pefloxacin (84%).

Conclusion: Proper hygienic practice should be promoted and avoidance of indiscriminate use of antibiotics in order to prevent the spread of resistant bacteria.
