Antibiotic resistance in Staphylococcus aureus isolated from one broiler farm at Cibangbara Village, Sukabumi District

Abstract

Antibiotics are widely used in poultry for therapeutic, prophylactic, and growth promotion purposes. S. aureus resistant to antibiotic, also an opportunist pathogen cause infection in human and animal. The aim of this research was to determine the antibiotic resistance of S. aureus were isolated from the cloaca swabs in from one broilers farm in Cibangbara Village, Sukabumi District. Fifteen S. aureus isolated showed present of S. aureus. The antibiotics that were used in this study were tetracycline, oxytetracycline, erythromycin, nalidixic acid, ampicillin, chloramphenicol and gentamicin. The resistance of S. aureus to various antibiotics was tested by the Kirby-Bauer method. The results were compared with Clinical and Laboratory Standards Institute (CLSI 2008). S. aureus isolates were resistant towards tetracycline (100%), oxytetracycline (100%), erythromycin (100%), nalidixic acid (60%), ampicillin (26.7%), chloramphenicol (20%), and gentamicin (6.7%). In conclusion, S. aureus showed resistant to tetracycline, oxytetracycline and erythromycin while still susceptible toward gentamicin and chloramphenicol.
