Antibiotic resistance profile of Staphylococcus aureus, Streptococcus spp. and Klebsiella spp. isolated form chicken farm in Bogor, Sukabumi, and Cianjur, West Java

Abstract

West Java province has largest population of chicken poultry, with Bogor, Sukabumi, and Cianjur has highest chicken population. Farmers used antibiotics for prophylaxis and therapy to maintain the production. However, extensive use of antibiotic increased the number of antibiotic resistant bacteria. Staphylococcus aureus, Streptococcus spp, and Klebsiella spp are the example of flora normal in chicken that affected with abusive use of antibiotic. The aim of this study was to determine the antibiotic resistance profile of S. aureus, Streptococcus spp., and Klebsiella spp. isolated from cloacal swab of chicken poultry in 3 regions. Total of 320 samples were collected and the positive number of S. aureus, Streptococcus spp., and Klebsiella spp were 61, 8, and 58 isolates respectively. The result of antibiotics susceptibility test showed that S. aureus was resistant to ampicillin (98%), erythromycin (95%), nalidixic acid (93%), tetracycline (92%), oxytetracycline (90%), enrofloxacin (69%), and ciprofloxacin (56%). Streptococcus spp. was resistant to tetracycline (100%) and doxycycline (87.5%). Klebsiella spp. was resistant to erythromycin (100%), ampicillin (94.83%) oxytetracycline (93.10%), tetracycline and nalidixic acid (89.66%), enrofloxacin (86.21%), and ciprofloxacin (81.03%). S. aureus, Streptococcus spp., and Klebsiella spp. has a high level of resistance to antibiotics and most of the isolates were multi-resistant.
