The effects of virulent and avirulent isolates of hemorrhagic enteritis virus were studied in Leghorn and broiler chickens. The viruses caused subclinical infections in both strains of birds. The avirulent isolate produced enlarged spleens, inclusion bodies, and antibody in all inoculated Leghorns. In broilers the avirulent virus produced infection in only half of the inoculated birds. Inclusion bodies were widely dispersed in the spleens of both types of birds. The virulent virus produced infection in all inoculated birds of both strains. Inclusion bodies were numerous in the spleens of Leghorn birds and were widely scattered in the spleens of broilers.
研究了出血性肠炎病毒的强毒株和无毒株对来亨鸡和肉鸡的影响。这两种病毒在这两种品系的鸡中均引起亚临床感染。无毒株在所有接种的来亨鸡中产生脾脏肿大、包涵体和抗体。在肉鸡中，无毒病毒仅在一半接种的鸡中产生感染。包涵体广泛分布于两种鸡的脾脏中。强毒株在两种品系所有接种的鸡中均产生感染。来亨鸡脾脏中的包涵体数量众多，在肉鸡脾脏中广泛散布。
