【摘要】：为探究禽心包积液-肝炎综合征的发病原因。对2016年7月天津市某家禽养殖场的病死鸡进行了大体病变检查、组织病理学检查、细菌学检验及其病毒的分离鉴定和回归试验等。结果显示,剖检以大量心包积液和肝脏肿大为主;组织切片H.E.染色观察到肝脏淤血、水肿,肝细胞变性、坏死且含有大量嗜碱性核内包涵体;细菌培养均为阴性;PCR检测禽腺病毒-4型(FAd V-4)呈现阳性;回归试验的结果与临床病例一致。最终诊断为禽心包积液-肝炎综合征,与I群4型禽腺病毒相关。病毒的致病性研究正在进行中。
[Abstract]:To investigate the pathogenesis of avian pericardial effusion-hepatitis syndrome. Gross pathological changes, histopathological examination, bacteriological examination, virus isolation and regression tests were carried out in a sick and dead chicken in a poultry farm in Tianjin in July 2016. The results showed that a large number of pericardial effusion and hepatomegaly were the main findings, and the histopathological sections were H. E. Liver congestion, edema, hepatocyte degeneration, necrosis and large number of basophilic inclusion bodies were observed by staining. The bacterial culture was negative, and FAd V-4 was positive by PCR. The results of regression test were consistent with clinical cases. The final diagnosis of avian pericardial effusion-hepatitis syndrome was associated with Avian adenovirus type I-4. Studies on the pathogenicity of the virus are under way.
