All collected specimens were subjected to the bacteriological investigations for isolation and identification of campylobacter species, Y. entrocolitica and Listeria monocytogen. Campylobacter J. biotype I was the single biotype of campylobacter species which was isolated from both diarrheal cases [4%] and chicken [20%] listeria monocytogen was more frequent among diarrheal bilharzial cases [10%] than nonbilharzial ones [4%], while Yersenia enterocolitica was detected at higher percentage among diarrheal nonbilharzial [8%] than bilharzial one [4%]. Listeria monocytogen and Y. enterocolitica were detected in chicken in percentage of [4% and 8% respetively]. Y. enterocolitic was isolated from [8% and 4%] of Lancho and cheese respectively
