Abstract
The present study was conducted for the isolation of bacterial pathogens that affected the gastrointestinal tract of chickens and economically affect their production. In this study 100 cloacal samples were collected from diarrheic chickens from 4 different private farms in Bilbies Sharqiyah Governorate and examined bacteriologically for its cause. The results revealed that there were 5 isolates: 39% E. coli, 22% C. perfringens,14% K. pneumoniae and 14% P. mirabilis, 11% P.vulgaris along with no detection of Salmonellae (0%). All 14 K. pneumoniae isolates previously identified using the traditional methods were identified rapidly and automatically by VITEK 2 system (bioMerieux, Craponne, France) using AST and ID-GNB cards, Vitek 2 software, Advanced Expert System [AES] software, and all 14 isolates were sensitive for 24 different antimicrobial agents: Cefazolin, Cefepime, Ciprofloxacin, Gentamycin, Tobramycin, Cefuroxime, Piperacillin, Amikacin, Meropenen, Cefotaxime, Trimethoprim sulfa, Ceftazidime, Levofloxacin, Chloramphenicol, Imipenem, Aztreonam, Cefoxitin, Amoxicillin/CA, Ticarcillin/CA, Minocycline, Ertapenem, Tigecycline, Moxifloxacin, Ampicillin/sulbactam.
