Isolation, Serotyping, Pathogenicity and Antibiotic Sensitivity Testing of Escherichia Coli from Broiler Chickens in Egypt

Nagwa Saeed Mouhammed Moustafa.


Abstract
Escherichia coli infections are of significant concern to the poultry industry. It is one of the most important and frequently encountered bacterial avian pathogens causing a wide variety of disease syndromes in birds, inducing up to 30% mortality. In this study, samples from the liver, heart blood, lung, air sacs, yolk sac and joints from diseased and freshly dead chickens from broiler and layer flocks were collected for the isolation and serotyping of E. coli. Nine E. coli serotypes were isolated and identified from 8 broilers and 1 layer flocks and they were O8 (3 strains), O27 (2 strains) and the other 4 isolates were O29, O115, O148 and O169, respectively. The in-vitro antibiotic sensitivity testing for these E. coli isolates revealed that all isolates were highly sensitive to cefotaxime, mostly higher sensitivity to amoxicillin + clavulanic acid, and intermediate sensitivity to doxycycline, and spiramycin.
Key Words: E. coli = Escherichia coli, isolation, antibiotic sensitivity.
