Abstract

Staphylococcus aureus is a Gram-positive bacteria causing pneumonia, mastitis, meningitis, and urinary tract infections. The emergence of Methicillin-Resistant Staphylococcus aureus (MRSA) as a highly pathogenic strain caused a health problem that needed more attention in both human and animal medicine. This research aimed to determine the type of antibiotic that was appropriate and effective in treating diseases caused by bacteria in animals and humans. The susceptibility test was carried out by the diffusion method using Mueller Hinton Agar (MHA) and against seven various antibiotic discs. The samples used for this test were 18 Staphylococcus aureus isolated from cow and goat’s milk and a nasal swab of a dairy farmworker. The results of the measured resistance zone formed were interpreted with a standard interpretation table of the Kirby-Bauer. The results showed that 18 Staphylococcus aureus isolates were resistant to ampicillin (100%), oxacillin (83,33%), penicillin-G (100%), tetracycline (72.22%). The isolates showed intermediate susceptibility to erythromycin (61.11%), oxacillin (5,56%), and sensitivity to gentamicin (100%), cefoxitin (77.78%), and oxacillin (11,11%). It was concluded that gentamicin and cefoxitin were still effective in treating diseases caused by Staphylococcus aureus.
