Examination of 866 apparently normal, diseased and dead broiler chickens of respectively with an all incidence of 40.2%.Examination of 2113 apparently normal, diseased and dead layerchickens of 2 different breeds (balady and Lohman breeds) revealed theisolation of Campylobacter with an incidence of 19.6% and 17.2%respectively with an all incidence of 18.6%. On identification, C. jejuni was the most predominant species at anincidence of 71.1 % followed by C. coli (22.2%) and C. laridis (6.7%).Different selective media including modified blood free Campylobacter selective agar, Skin-ow’smedia, blood agar with antibiotics and thioglycollate media as well as filtration method were checked for Campylobacter isolation and it was found that the highblood agar with antibiotics (21.8%), filtration method (21.1 %) andthioglycollate media (20.5%).
