Abstract

Broiler chicken is one of the most common forms of protein in Indonesia. Sukabumi and Cianjur are two of the province of West Java’s top producers of broiler chickens. Farmers nonetheless use antibiotics for prevention, treatment, and growth enhancement. The objective of this investigation is to detect antibiotic resistance and the related resistance gene. The cloacal swab samples were determined to be Staphylococcus aureus by biochemical and molecular assays. Against the positive S. aureus strains, the antibiotics tetracycline, ampicillin, gentamicin, nalidixic acid, ciprofloxacin, erythromycin, and chloramphenicol were evaluated. The colony’s obvious inhibitory zone was evaluated in accordance with the 2018 Clinical and Laboratory Standard Institute recommendations (CLSI 2018). After extracting the DNA from resistant strains, the polymerase chain reaction (PCR) method was employed to identify the resistance gene. The total number of S. aureus isolates from both regions was 26, with 14 coming from Sukabumi and 12 from Cianjur. The vast majority were resistant to the vast majority of antibiotics used in broiler farms including several medicines. These samples carried the genes blaTEM, gyrA, tetA, and ermB for antibiotic resistance.
