From 375 aborted sheep and goat fetus, 7 [1.8%] Salmonella abortus ovis were isolated. From 45 cases of diarhetic cows and calves 7 [15.5%] salmonellae were isolated, that 71% of them S. enteritidis and 29% were S.typhimurium. From 20 case of human that suspicious to salmonellosis collected the bone marrow, 3 [15%] salmonellae were isolated which 66.61 [2 case] of them were S.typhi and 33.3 [one case] was S.enteritidis. From 429 case of human blood culture suspicious to salmonellosis 13 [3.0%] salmonellae were isolated that 61.5% of them were S.typhi and 23.1% S.paratyphi A and 15.4% were S.enteritidis. The result obtain in the survey showed that 89.5% of salmonellae were S.enteritidis. S.enteritidis is an important cause of enteritis and food poisoning in human and animal.
