Over a period of 20 years, a total of 207 Mannheimia haemolytica samples were isolated from calves affected with pneumonic pasteurellosis and serotyped by the indirect haemagglutination test. Serotypes A1 (102 isolates), A2 (47 isolates) and A6 (42 isolates) were most common; in addition, 16 isolates were serotypes A7, A13, A14 or untypable. The relative prevalence of serotype A6 has increased recently in Japan, as has been reported from other countries. The results of this study provide useful information towards the design of efficient vaccines for the prevention of M. haemolytica infection in Japan.
在20年的时间里，共从患有肺炎巴氏杆菌病的犊牛中分离出207份溶血曼氏杆菌样本，并通过间接血凝试验进行血清分型。血清型A1（102株分离株）、A2（47株分离株）和A6（42株分离株）最为常见；此外，16株分离株为血清型A7、A13、A14或无法分型。血清型A6的相对流行率最近在日本有所上升，其他国家也有相关报道。本研究结果为设计预防日本溶血曼氏杆菌感染的高效疫苗提供了有用信息。
