关于我国种猪场猪肺炎支原体净化的思考

Reflections on Elimination of Mycoplasma hyopneumoniae in Chinese Breeding Pig Farms

猪肺炎支原体是一种对生猪影响较大的细菌性病原体,往往可引起猪群发生慢性感染,且难以从猪群和猪场水平上清除,导致养猪业遭受巨大的经济损失。猪肺炎支原体净化在欧洲和北美已全面启动,且有成功案例,我国才刚刚启动。本文结合国外猪肺炎支原体净化方案的经验与我国生猪养殖特殊性的分析,提出分群体、分阶段的“三步法”净化建议,并对我国猪肺炎支原体的净化提出了展望。

Mycoplasma hyopneumoniae(M.hyopneumoniae)is a bacterial pathogen that significantly affects pigs,often causing chronic infections in swine herds that are challenging to eliminate at the herd and farm levels,resulting in substantial economic losses in the swine industry.Elimination of M.hyopneumoniae has been extensively implemented in Europe and North America with successful cases,while China has recently initiated this process.This paper,combining the experience of foreign M.hyopneumoniae elimination programs with the analysis of the unique characteristics of pig farming in China,proposes a"three-step"elimination approach based on grouping and staging,offering insights into the purification of M.hyopneumoniae in China.
