Occurrence and antibiogram profile of Staphylococcus aureus isolated from some hospital environment in Zaria, Nigeria

Staphylococcus aureus is an opportunistic pathogen and is the most frequent cause of hospital acquired infection. A total sample of 310 was collected for this work; the pathogen was isolated from hands of some healthcare workers/nurses, operation tables, door knobs/door handles, nurses’ table tops, bedrails, stretchers, floors, toilets seats, cupboards, and sinks. The total percentage prevalence of the pathogen in Major Ibrahim B. Abdullahi memorial hospital was 16.8% and 20.7% from St. Luke’s Anglican hospital. Kirby-Bauer-NCCLS modified single disc diffusion technique was used to determine the antibiogram profile of the pathogen at 0.5 scale MacFarland’s standard (1.5 × 108 cells/ml). The isolates from the two hospitals were 100% susceptible to vancomycin and 95.7% and 92.6% from Major Ibrahim B. Abdullahi memorial hospital and St Luke’s Anlgican hospital respectively were resistant to Ampicillin.
