[目的]牛支原体肺炎是严重危害国内外肉牛养殖业的一种重要疾病,病原混合感染将加剧病情,增加临床治疗难度。本研究通过阐明我国牛支原体肺炎混合感染情况,为探讨更加有效的防控手段提供参考依据。[方法]近4年来采用门诊和出诊的方式,收集了全国范围内35个临床初诊为牛支原体肺炎的牛场病牛样本,进行牛支原体及混合感染细菌的分离和分型鉴定。[结果]确定了这类疾病的细菌学感染特征,表现为牛支原体感染占绝对优势,混合感染模式主要以牛支原体合并多杀性巴氏杆菌A型感染、牛支原体合并和化脓隐秘杆菌感染为主。[结论]经实验室检测证实临床初诊病例绝大部分为牛支原体肺炎,但混合感染很普遍。

[Objective]Mycoplasma bovis （M. bovis） pneumonia is a serious disea tle industry. Co-infection of M. bovis with other pathogens will augment this diseas investigate the bacterial spectrum of this disease and therefore provide the evidence se that harms beef cat- e. This paper aimed to to improve the control measures. [Method]In the last 4 years, the samples of diseased cattle were collected from 35 beef cattle farms clinically diagnosed as M. boris pneumonia, and bacterial isolation and typing were carried out using cultural isolation and molecular tests. [Result] M. bovis was absolutely dominant type in this disease. The co-infection patterns were mainly expressed as infection of M. bovis with Pasteurella multocida type A and M. bovis with Arcanobacterium pyogenes. [Conclusion]Most of the clinical cases was determined to be infected by M. bovis. However,the co-infection was very popular.
