The prevalence of extended spectrum β–lactamase producing E. coli isolated from chickens in El-sharkia Governorate

E. coli producing extended spectrum beta-lactamase (ESBL) in poultry has a major concern due to the possible transmission between them and human that may cause public health threat. Our study is directed estimate prevalence of resistance pattern characterization ESBL producibility genes isolated from chicken respiratory tract chiken farms El-Sharkia Governorate. 250 samples 50 were collected. Isolation identification serotypes performed. In addition, Antibiotic Resistance Profile (ARP) against β-lactam antibiotics, phenotypic screening PCR for genes; SHV TEM, done. The results showed 140 isolates out total (56%) morphologically biochemically positive coli. Different serogroups exhibited high rates 14 antibiotics. 35.7 % E recorded be phenotypically ESBL-positive bacteria. Genotypically, including bla TEM detected (100%) 30 (60%), respectively. conclusion, Governorate would account economic threat society.
