BACTERIOLOGICAL AND PATHOLOGICAL STUDIES ON ENTERIC ORGANISMS WITH SPECIAL REFERENCE TO SALMONELLA AMONG SLAUGHTERED COWS AND BUFFALOES IN ISMAILIA GOVERNORATE
Animal Health Research Institute, Agricultural Research Centre, Dokki, Giza, Egypt
Abstract
Bacteriological and pathological studies were carried out on 500 animals (336 cows and 164 buffaloes) slaughtered in two abattoirs at Ismailia Governorate, Egypt. From these animals 1500 proper samples were taken from small intestine, mesenteric lymph nodes and liver. The bacteriological examinations of these organs revealed that the total average percent of enteric bacterial isolates in cows was 66.6% and in buffaloes was 59.1%. The bacterial isolates were identified as E. coli, Salmonella, Enterobacter, Proteus, Klebsiella, Citrobacter, Yersenia and Edwardsiella. The percentage of these infections varied in both cows and buffaloes. The isolated Salmonella spp. were identified as Salmonella enteritidis and S. cerro with a percentage of infection in cows 13.98% and 7.47%, while, in buffaloes it was 10.4% and 3.65%, respectively. Salmonella enteritidis phage type 4 was diagnosed in both cows and buffalo Salmonella. Most of the enteric isolates did not influence the gross and histological structure of the examined organs. However, in E.coli, Salmonella spp. and Yersinia infections, the pathological changes in intestine, mesenteric lymph nodes and liver were pronounced and differed in their severity according to the type of infection. These changes were illustrated and discussed.
