| Abstract | ||
| 600 samples were collected from diarrheic broiler chickens and from apparently normal chickens in Fayoum Governorate .The bacteriological examination revealed that a total of 530 bacterial isolates were recovered from the 600 broiler chickens under examination. Cloacal swabs (130), cecal contents (350), unabsorbed yolk sac (40), liver and gall bladder (40) and heart blood (40). Concerning the type of isolated bacteria from broiler chickens E. coli was the predominate (59.3) %. 53.3%of isolates were from diarrheic birds and 6.0% from apparently healthy chickens, followed by Proteus mirabilis (14.8%). Out of them were 11.6% from diarrheic birds and 3.2% from apparently healthy birds. And Proteus vulgaris (3.3%). Out of them were 2.5% from diarrheic broiler chickens and 0.8% from apparently healthy one. E. coli was the most predominant bacteria recovered from the examined cases. 50 isolates of E. coli which were isolated from large intestines tested for in vitro pathogenicity using Congo red dye. The result showed fundamental variation for the growth of E. coli of diarrheic and apparently healthy origin on Cango red dye as 86% of E. coli isolated from chickens gave red colonies (pathogenic) while 16% of E. coli isolates did not bind to Congo red dye gave white colonies (non pathogenic). Eight E. coli isolates recovered from examined diseased broiler chickens were serotyped and revealed the following : 3 isolates O114 K90, 2 isolates O26 K60, 2 isolates and one isolate O91 K - . Ten Salmonella spp. isolates recovered from examined diseased broiler chickens were serotyped and revealed that 6 isolates were belonging to Salmonella Enteritidis and 4 isolates belonged to Salmonella Virchow. Aeromonas hydrophila, Salmonella Enteritidis, Salmonella Virchow and E. coli were examined for antibiotic sensitivity test. It was found that Aeromonas hydrophila isolates were sensitive to gentamycin, doxycycline, norfloxacin, enrofloxacin, chloramphenicol and ciprofloxacin, Salmonella Enteritidis isolates were sensitive to chloromphenicol, enroloxacin, norfloxacin, colistin, ciprofloxacin and Gentamycin, neomycin and doxycycline, but Salmonella Virchow isolates were sensitive to chloromphenicol, enrofbxacin, norlooxacin, colistin, neomycin, ciprofloxacin, gentamicin, cephalexin and doxycycline, while E. coli isolates were sensitive to gentamicin, doxycycline and norfloxacin, chloramphenicol, cephalexin, norfloxacin and colistin. | ||
