ABSTRACT
E. coli was recovered from 59.00% of septicemic broiler chickens suffering enteritis, perihepatitis and airsacculitis. Pyocin typing of chosen E. coli isolates revealed two types. The first type was able to grow in the presence of pyocin [PREC]. The second type was unable to grow in the presence of pyocin [PSEC]. There is no correlation between pyocin typing and dermonecrotic test or pyocin typing and pathogenicity for day-old chicken. But there is a correlation between dermonecrotic test and pathogenicity for day-old chicks. Thus, virulent types of E. coli can be detected through the dermonecrosis of their whole cell lysates [WCL] in the skin of guinea- pigs
