Abstract: A total of 180 ear and nasal swabs were collected from clinically healthy goats, sheep, cattle, pigs and rabbits at the University Farm and were examined for staph. aureus using mannitol salt agar. The antibiotic susceptibility profiles of the Isolates were determined using ciprofloxacin, penicillin, cloxacillin, ampicillin, chloramphenicol, Lincomycin, Septrin, tetracycline, gentamycin, rifampicin and erythromycin. Rifampicin 94.3% and streptomycin 80.7% were the most sensitive of all the fifteen antibiotics used. Amoxycilin 72.9% and septrin 62.2% were the most resistance drugs. Out of the 135 Isolates, 107 79.3% showed multiple resistance ranging from two to thirteen drugs. The increasing antibiotic resistance of Staph. aureus isolates of livestocks in the University Farm should be a serious cause for concern to clinicians to devise ways of reducing the prevalence of this bacterium in farm animals. This will inadvertently prevent epidermic of life threatening infection among the animals in the Farm.
