Background: Staphylococcus aureus is the most common pathogenic bacteria that causes staphylococcal
food poisoning, a form of gastroenteritis with rapid onset of symptoms. The development of multiple
drug resistance to this organism is posing serious threat to human health; these bacteria also have plenty
of virulence factors which contribute to infection.
Results: Ampicillin, penicillin, and amoxicillin were the least effective. Norfloxacin, cephalexin,
ciprofloxacin, rifampicin, clindamycin and vancomycin were the most effective antibiotics by in vitro
sensitivity testing.
Conclusion: S. aureus isolates from foodstuff were producers of a variety of extracellular hydrolytic
drug resistance.
