Objective: To determine the multidrug resistance extended spectrum p-lactamase and AmpC(ESBL/AmpC producing) Escherichia coli(E. coli) isolated from the environment of Bogor slaughterhouse, ***: A total of 35 samples from 7 locations in slaughterhouse i.e., source of water,slaughtering floor, swab of carcass area floor, swab of evisceration area floor, untreated waste water, treated waste water, drinking water for cattle were collected from March to April 2016. Presence of ESBL/AmpC producing E. coli and susceptibility testing against8 antimicrobial agents(penicillin G, streptomycin, gentamycin,ciprofloxacin, enrofloxacin, tetracycline, trimethoprim-sulfamethoxazole, and polymyxin B) were detected by disk diffusion test according to Clinical and Laboratory Standards ***: ESBL/AmpC producing E. coli were identified in 14.3%(5/35) of the collected samples from the environment of Bogor slaughterhouse. ESBL/AmpC-producing E. coli isolates were detected in untreated waste water(n=3), slaughtering floor(n=1), and carcass area floor(n=1). Most of ESBL/AmpC-producing E. coli isolates(80%) showed multidrug resistance phenotypes against at least three classes of antibiotics. The highest incidence of antibiotics resistance was against penicillin G(100.0%) and streptomycin(100.0%), followed by gentamicin(60.0%), trimethoprim-sulfamethoxazole(60.0%),tetracycline(40.0%), ciprofloxacin(40.0%), enrofloxacin(20.0%), and polymyxin B(0.0%).Conclusions: The transmission of antimicrobial resistant bacteria into the environment may be a potential risk for human health.

Objective: To determine the occurrence of CTX-M producing Escherichia coli(E. coli)from cattle feces in Bogor slaughterhouse, ***: A total of 220 cattle feces samples were collected from Bogor slaughterhouse from March to April 2015. Presence of extended-spectrum beta-lactamase(ESBL) producing E. coli was detected by disc diffusion test based on the recommendation from Clinical and Laboratory Standards Institute(2014). Bacterial strains which were confirmed as producing ESBLs were further analyzed for the presence of bla genes of the ESBL by ***: The results showed that CTX-M producing E. coli isolates were detected in 19 samples from 220 samples(8.6%). The b-lactamase genes detected were CTX-M-1(n = 10) and CTX-M-9(n = 9). All of the CTX-M producing E. coli isolates showed multidrug resistance phenotypes to at least four antibiotics. The highest incidence of antibiotics resistance was showed to ampicillin(100.0%), cefotaxime(100.0%), and cefpodoxime(100.0%), followed by streptomycin(84.3%), trimethoprim-sulfamethoxazole(73.7%), erythromycin(52.6%), kanamycin(26.3%), doxycycline(10.5%), and ceftazidime(0.0%).Conclusions: Detection of CTX-M-producing E. coli in cattle feces raises important questions as they can represent a potential risk factor to public health.
