疑似猪瘟病例的病理学诊断

The Pathological Diagnosis of Suspected Swine Fever

对送检的42例疑似猪瘟或伪狂犬病病例样品进行了病理学诊断。样品主要包括扁桃体、淋巴结、脾脏、肺脏、肾脏、肠、脑等,通过甲醛固定,石蜡切片,H.E.染色后进行显微镜下观察,结果显示,主要的病理变化包括扁桃体炎、脾炎、淋巴结炎、肠炎、肺炎、肾小球分叶增多、脑膜脑炎,未见伪狂犬病嗜酸性包涵体。结合相关病理学知识,初步判定疑似猪瘟。

42 samples which were suspected of swine fever or pseudorabies were sent to TSE laboratory for pathological diag- nosis. These samples mainly included tonsils, lymph nodes, spleens, lungs, kidneys, intestines, brains, etc. After formalin-fixation, paraffin sections and H.E. staining, these paraffin sections were observed under the microscope and the results showed that the main pathological changes included tonsillitis, splenitis, lymphadenitis, enteritis, pneumonia, increased glomerular lobulation and meningoencephalitis. Importantly, no eosinophilic inclusion bodies characteristic of pseudorabies was found. According to these ob- served results and related pathological knowledge, we concluded that these pigs were most t}ossiblv infected with swine fever
