ABSTRAKPenelitian ini bertujuan untuk membandingkan pola resistensi antibiotik isolat Enterobacteriaceae dari daging broiler dan daging ayam kampung di Surabaya, Indonesia yang diisolasi pada tahun 2016-2017. Metode Kirby-Bauer difusi disk digunakan untuk menentukan resistensi isolat terhadap tetrasiklin (TE), gentamisin (CN), cefoxitin (FOX), sulfametoksazol-trimetoprim (SXT), asam nalidiksat (NA), dan kloramfenikol (C). Isolat daging broiler dan daging ayam kampung resisten terhadap keenam antibiotik yang diuji. Secara keseluruhan, isolat daging broiler yang resisten terhadap TE, CN, FOX, SXT, NA, C adalah 57,76% lebih tinggi dibandingkan isolat daging ayam kampung. Lebih dari 50% dari seluruh (304) isolat daging broiler resisten terhadap TE dan NA, sedangkan lebih dari 50% dari seluruh (310) isolat daging ayam kampung hanya resisten terhadap TE. Pada kedua jenis daging ayam, strain resisten ditemukan pada isolat Salmonella spp., Escherichia coli, Shigella spp., Citrobacter spp., Klebsiella spp., Yersinia spp., Proteus spp., Enterobacter spp., Serratia spp., Edwardsiella spp. Strain resisten antibiotik isolat daging broiler secara signifikan lebih tinggi (P <0,05) dibandingkan isolat daging ayam kampung, kecuali Edwardsiella spp. Secara keseluruhan, isolat Enterobacteriaceae yang resisten multi-obat ditemukan lebih tinggi pada daging broiler dibandingkan daging ayam kampung. Daging ayam broiler dan daging ayam kampung berpotensi sebagai reservoir Enterobacteriaceae yang resisten multi-obat dan dapat mengancam kesehatan masyarakat.
ABSTRACTThis study aimed to compare the antibiotic resistance patterns among original Enterobacteriaceae isolates from broiler and backyard chicken meats in Surabaya, Indonesia, isolated in 2016-2017. The 228 J.Indonesian Trop.Anim.Agric. 44(2):228-240, June 2019 Kirby-Bauer disk diffusion method was used to determine the resistance of these isolates against tetracycline (TE), gentamicin (CN), cefoxitin (FOX), sulfamethoxazole-trimethoprim (SXT), nalidixic acid (NA), and chloramphenicol (C). Both broiler and backyard chicken meat isolates were resistant to the six antibiotics tested. Overall, broiler meat isolates which resistant to TE, CN, FOX, SXT, NA, C were 57.76% higher than backyard chicken meat isolates. More than 50% of broiler meat isolates (304 samples) were resistant to TE and NA, whereas backyard chicken meat isolates (310 samples) were only resistant to TE. The resistant strains found in both meat isolates were Salmonella spp., Escherichia coli, Shigella spp., Citrobacter spp., Klebsiella spp., Yersinia spp., Proteus spp., Enterobacter spp., Serratia spp., and Edwardsiella spp. Resistant strains of broiler meat isolates were significantly higher (P<0.05) than backyard chicken meat isolates, except Edwardsiella spp. Overall, multidrug-resistant Enterobacteriaceae was found to be higher in broiler meat isolates than in backyard chicken meat isolates. Broiler and backyard chicken meats are potential reservoirs of multidrug-resistant Enterobacteriaceae which threat to publ...
