Abstract | This study was conducted to determine the pathological findings of intestine and liver of chickens at Alexandria province during the period from February 2015 to March 2016. The livers and intestines were taken from different breeds of 100 chickens (67 White broilers, 19 Saso and 14 Balady) and were investigated for bacteriological, parasitological and pathological examination. The bacteriologic results revealed that E.coli and Salmonella gallinarum were the predominant isolated bacteria from hepatic tissues of all examined breeds. Regarding intestinal samples, E.coli was the main isolated bacteria followed by Clostridium perfringens. Parasitological examination showed that Balady chickens was the most affected breed with coccidiosis followed by Saso and White broilers. Hepatic necrosis was the chief hepatic lesion recorded in White broilers (29.41%), Saso (35.71%) and Balady breeds (30.34%). Moreover, necrotic enteritis was the major intestinal lesion recorded in Saso, Balady and White broilers at frequency of (81.25%), (68.75%), (67.80%), respectively. Finally, it could be concluded that colibacillosis is the most prevalent disease affect different chicken breeds at Alexandria province. In White broilers, Clostridium perfringens is the most bacteria that accompanying necrotic enteritis and coccidiosis was widespread among the chickens of this breed.
