E.coli was isolated by percentage of 3Meanwhile Salmonellae were isolated by percentage of 42% from the first farm while it was failed to be detected in the second farm. Overall incidence of Proteus species, Citrobacter species, Pseudomonas-species, Enterobacter species, Edwardsiella species,Regarding the serotyped E. coli strains in relation to a total of 42 E. coli isolates, it was found that 0119: K69, 055:K59, 0111 :K58, 086:K61 and untypable, were identified with the percentage of 4.8, 14.3, 19,23.8 and 38.1, respectively. The virulence,prevalence was found with the age of 6th week (32.6%) and the lowestfrequency in both 2nd and 5th week of age (6.5% both). Salmonella was
