A Pasteurella haemolytica-like organism was isolated from the intestines of 28 swine with clinical, gross, or microscopic evidence of enteritis. In 15 cases, other known enteric pathogens were also demonstrated, and in 13 cases, no other pathogens were detected. The mean age of affected animals was 44 days. Most of the animals had clinical evidence of diarrhea. Gross enteric lesions were present in 17 of 21 cases. Microscopic lesions were present in 24 of 26 cases. A diffuse or segmental moderate to severe necrotizing enteritis was the most common lesion in cases in which only the Pasteurella haemolytica-like organism was isolated. Biochemical tests gave results consistent with Pasteurella haemolytica, and 5 of 15 isolates met criteria for biotype A. Negative results were found with an indirect haemagglutination procedure for P. haemolytica.
从28头有肠炎临床、大体或显微镜检查证据的猪的肠道中分离出一种类溶血巴斯德菌。15例中还检出了其他已知的肠道病原体，13例未检测到其他病原体。患病动物的平均年龄为44天。大多数动物有腹泻的临床证据。21例中有17例存在肠道大体病变。26例中有24例存在显微镜下病变。在仅分离出类溶血巴斯德菌的病例中，最常见的病变是弥漫性或节段性中度至重度坏死性肠炎。生化试验结果与溶血巴斯德菌一致，15株分离菌中有5株符合生物型A的标准。溶血巴斯德菌间接血凝试验结果为阴性。
