猪支原体肺炎研究进展

Advance in the Mycoplasmal Pneumonia of Swine

猪支原体肺炎是猪肺炎支原体所引发的一种以气喘为主要症状,以肺部对称性肉变为主要病理变化的慢性接触性呼吸道传染病,在世界各地普遍存在,严重危害养猪业的健康发展。随着对猪肺炎支原体的深入研究,发现其单一感染致死率虽低,但是易引发其他病毒或细菌等病原的续发或并发感染,导致猪呼吸道疾病综合征,使得疫情变得更为复杂,增加猪病诊断与防控的难度,造成巨大的经济损失。论文根据猪肺炎支原体的最新研究进展,从病原学、流行病学特点、主要抗原蛋白的研究、诊断、疫苗研制、防控措施等六个方面做一综述,从而为猪肺炎支原体的进一步研究及该病的防控提供新思路。

Mycoplasmal pneumonia of swine caused by Mycoplasma hyopneumoniae was the chronic and contagious respiratory disease ,whose main symptom is asthma and main pathological lesion is was symmetrical polypoid lesion. It is widespread all over the world and restrictes the development of livestock breeding. Following the research of Mycoplasma hyopneumoniae gradually, it is found its fatality rate of simplex infection is low. However, the secondary infection and mixed infection of virus or bacteria are ini- tiated easaily, which result in porcine respiratory disease complex and more complicated epidemics. At the same time, it increases the difficulty for diagnosis and prevention, and results in huge economic losses. Based on the latest research progress, the etiology, the epidemiology, the main antigens, the diagnosis, the development of vaccine and the prevention and control measures of Mycoplasma hyopneumoniae, were discussed so as to provide new ideas for the further research and the prevention of the Mycoplasrna hyopneumoniae.
