摘要:

旨在了解山羊感染绵羊肺炎支原体的组织病理变化情况。通过设立感染组和对照组,每组5只,采集各分组试验用羊的血清、鼻拭子、肺组织、气管以及支气管。对血清进行绵羊肺炎支原体抗体ELISA检测,利用鼻拭子进行绵羊肺炎支原体特异性PCR检测,对肺、气管和支气管进行组织病理学观察。结果显示,在剖检中发现肺组织有不同程度的纤维素性肺炎、肝变和肉样变;样本血清中存在绵羊肺炎支原体抗体;PCR产物呈现特异性条带;肺组织、气管和支气管均呈现不同程度的病理学特征。绵羊肺炎支原体感染的山羊表现出明显的组织病理变化,包括肺部的炎症反应、血清学抗体的产生以及绵羊肺炎支原体核酸在肺组织中呈阳性,这些结果为山羊感染绵羊肺炎支原体的诊断和研究提供了有力的科学依据。

Abstract:

This study aimed to understand the histopathological changes of goats infected with Mycoplasma ovipneumoniae. An infection group and a control group (5 goats each) were established. Serum, nasal swabs, lung tissue, trachea, and bronchi were collected from each group. Mycoplasma ovipneumoniae-specific antibodies in serum were detected by ELISA, Mycoplasma ovipneumoniae-specific nucleic acids in nasal swabs were identified by PCR, and histopathological examination was performed on lung, tracheal, and bronchial tissues. The results showed that there were varying degrees of cellulosic pneumonia, liver hepatization and carnification in the lung tissue during the autopsy; There were Mycoplasma ovipneumoniae antibodies in the sample serum; The PCR amplification produced specific bands; The lung tissue, trachea and bronchus showed different degrees of pathological characteristics. Goats infected with Mycoplasma ovipneumoniae pneumonia showed obvious histopathological changes, including lung inflammation, the production of serologicalantibodies and positive detection of Mycoplasma ovipneumoniae nucleic acids in lung tissues. These results provide a strong scientific basis for the diagnosis and research of Mycoplasma ovipneumoniae in goats.
