Potential Hazards of Antibiotics Resistance On Escherichia Coli Isolated From Cloacal Swab In Several Layer Poultry Farms, Blitar, Indonesia.

Objective: The study was isolated Escherichia coli from cloacalswab of layer poultry farms in Blitar area to investigate their antibiotic sensitivity pattern. Materials and Method: Fourty swab cloacal samples were collected from 8 farms where located in Blitar for 3 months. In order for MacConkey agar to be a medium for inoculation and biochemical tests to identify isolates such as IMViC and TSIA test were performed. The method of antibiotic sensitivity pattern of Escherichia coli was tested by disk diffusion. Results: The result revealed40 samples, 34 samples were exposed to contamination by E.coli. The pattern of antibiotic sensitivity showed high resistance against ampicillin (62%), ciprofloxacin (56%), tetracycline and trimethrophim sulfamethoxazole (53%). Sensitive antibiotics were also observed for amoxicillin clavulanic acid, cefepime, ampicillin sulbactam, amikacin and meropenem. The presence of MDR and ESBL-producing Escherichia coli isolated from cloacal swabs of layer poultry farms in Blitar were 47.1% (16/34) and 5.9% (2/34), respectively. Conclusion: This research to find out exposed the layer poultry farms to consider critical antibiotic resistance of E. coli and regarded potential public health hazards. [ABSTRACT FROM AUTHOR]
