CASES OF MULTIDRUG RESISTANCE (MDR) AND EXTENDED SPECTRUM BETA-LACTAMASE (ESBL) PRODUCING ESCHERICHIA COLI FROM BROILER CHICKEN IN BLITAR, INDONESIA

The study was isolated Escherichia coli from cloacal swab of broiler chicken farms in Blitar area to investigate cases of Multidrug Resistance (MDR) Escherichia coli and their Extended Spectrum Beta-Lactamase (ESBL) producing Escherichia coli. This research was conducted on broiler chicken farms in Blitar district in June until August 2019. Samples using cloaca swabs on broiler chickens were 160 animals from 6 districts in Blitar district. Samples were taken at random and brought to the laboratory for isolation of Escherichia coli bacteria. Positive isolates of Escherichia coli were tested for antibiotic sensitivity and Escherichia coli resistant to beta lactam groups were then confirmed using the Double Disc Synergy Test (DDST) confirmation test, to confirm as ESBL-producing bacteria. The results showed the percentage of antibiotic resistance to Escherichia coli bacteria in broilers in Blitar District was 88.75% (Ampicillin), 78.75% (Streptomycin), 76.87% (Erithromycin), 50.63% (Tetracyclin) and 75% (sulphamethoxazole-trimethoprim). The incidence of Multi-Drug Resistant (MDR) Escherichia coli bacteria in Broiler chickens in Blitar District was 85.63%, and around 28.75% were Escherichia coli bacteria that produce Extended Spectrum Beta-Lactamase (ESBL). In conclusion, the high level of ESBL-producing Escherichia coli in broiler chicken cloaca swabs is a threat to public health and the environment and is an important concern to reduce the rate of its spread.
