Antibiotic Resistance and Virulence Gene Patterns Associated with Multi Drug Resistant Avian Pathogenic <i>Escherichia coli</i> (APEC) Isolated from Broiler Chickens in India.

ABSTRACT: In the present study, a total of 102 samples were collected from chickens of different flocks, died due to suspected colibacillosis. Bacteriological and PCR methods were applied to detect avian pathogenic Escherichia coli (APEC). Phenotypic antimicrobial resistance (AMR) was determined by disk diffusion method. Extended spectrum beta lactamases (ESBL) detection was carried out via PCR by targeting blaTEM, blaSHV, blaOXA, and blaCTX-M groups 1, 2, and 9. Genes of eight virulence factors and class I integrons were also detected by PCR using gene specific primers. Culture, microscopic, biochemical tests and PCR recognised 69/102 (67.64%) samples as E. coli. Phenotypic AST revealed higher resistance against fluoroquinolone antibiotics, i.e., enr
