| Abstract |
| Escherichia coli is a gram-negative and non-spore-forming bacillus, a common inhabitant in the intestinal tract of poultry. The recovered isolates were examined bacteriologically. E. coli in the examined diseased chickens was 20% (20/100).All isolates were confirmed morphologically and biochemically.Concerning the phenotypic characteristics of recovered E. coli isolates were appeared as Gram-negative moderate size and non-sporulated rods under microscope. The bacteria gave characteristic pink colonies on MacCkoneys's agar and metallic sheen colonies on EMB. Biochemically, all isolates were positive with respect to catalase, lactose fermentation, indole, and methyl-red tests, while they were negative for cytochrome oxidase, Voges-Proskauer, citrate-utilization, H2S production, and urease tests. The antibiotics profile of E. coli isolates showed the highest resistance to ampicillin, gentamycin, Trimethoprim/Sulfa, Ciprofloxacin (100%) followed by Ceftoxime(66.7%), and E. coli isolates showed the highest sensitivity to Tigecycline, Meropenem, Cefoxitin and Aztreonam(100%) and all isolates were MDR.Regular screening and monitoring of antibiotic-resistant E.coli strains are required to develop an effective intervention programme in Egypt. |
