An intestinal pathogenic Escherichia coli isolate from calf diarrhea, containing the iutA, f17A, afa-8D, and cnf2 genes, was able to cause avian colibacillosis after experimental infection in chickens. Intra-tracheal inoculation and spray of this strain caused 10% of mortality and gross lesions, including airsacculitis, pericarditis, and perihepatitis. These results suggest that some bovine pathogenic E. coli can cause extra-intestinal infections in other animal species.
从犊牛腹泻中分离到一株含有 iutA、f17A、afa-8D 和 cnf2 基因的肠道致病性大肠杆菌分离株，在鸡的实验感染后能够引起禽大肠杆菌病。经气管内接种和喷雾接种该菌株可导致 10%的死亡率和明显的病变，包括气囊炎、心包炎和肝炎。这些结果表明，一些牛源致病性大肠杆菌能够引起其他动物物种的肠道外感染。
