Extended spectrum β-lactamase (ESBL) OF

\nExtended Spectrum β-Lactamase (ESBL)-producing Escherichia coli is a type of bacteria that can cause several infectious diseases in various animal and human tissues. ESBL bacteria have been reported to be resistant to various classes of antibiotics including penicillin, third-generation cephalosporins (cefotaxime, ceftriaxone and ceftazidime), and monobactam (aztreonam). This study focused on the presence of Escherichia coli as an ESBL producer in the cloaca of broiler. The purpose of this study was to determine the presence or absence of ESBL-producing Escherichia coli in the cloaca of broiler in the traditional market, Banda Aceh. This study used 47 samples of broiler cloacal swabs. The study used Cross-Sectional Observation and the disc diffusion methods. The presence of ESBL-producing Escherichia coli in cloacal swabs was identified using Eosin Methylene Blue Agar (EMBA) media. Detection of ESBL production using β-lactam antibiotic discs, namely cefotaxime, ceftazidime and ampicillin. The results showed the presence of ESBL-producing Escherichia coli bacteria isolated from cloacal swabs of broiler in the traditional market, Banda Aceh, which reached 21.27% (10/47). Sensitivity test results showed high resistance of Escherichia coli to cefotaxime 100% (10/10), ceftazidime 90% (9/10), and ampicillin 70% (7/10). Referring to CLSI, all isolates (100%) were ESBL-producing Escherichia coli. Based on the results of the study, it can be concluded that there is Extended Spectrum β-lactamase (ESBL) producing Escherichia coli in the cloaca of broiler in the traditional market, Banda Aceh.\n
