Antimicrobial resistance on escherichia coli from poultry production on blitar, Indonesia

The use of antibiotics in poultry can encourage antibiotic resistance, one of which is Escherichia coli which produces Extended Spectrum Beta-Lactamase. Extended Spectrum Beta-Lactamase is most produced by Escherichia coli. This study was carried out in a cross sectional descriptive manner aimed to determine the prevalence of ESBL in Escherichia coli bacteria in layer and broiler chicken farms in Talun and Kademangan subdistricts, Blitar district. Samples of 76 cloacal swabs were taken from laying hens and broilers. Positive isolates of Escherichia coli were tested for antibiotic sensitivity on agar-resistant MuellerHinton agar and Escherichia coli-resistant beta lactam (ampicillin) groups and then confirmed using the Double Disc Synergy Test, to confirm as Escherichia coli producing ESBL. The results showed a high prevalence of MDR in commercial chicken farms in Blitar district. Escherichia coli has MDR resistance properties in Layer Chicken in Talun sub-district by 88.23%, and in Kademangan sub-district by 63.16%, while for Broiler chickens in Talun sub-district by 90% and in Kademangan sub-district by 100%. The prevalence of Escherichia coli producing ESBL in Kademangan Sub-district was 15.79% and in Talun subdistrict by 5.88%, while in Broiler chickens in Kademangan sub-district was 85%, and in Talun sub-district the Escherichia coli producing ESBL was not detected.
