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.
