摘要:

 为了解2006-2010年湖北省地区暴发的鸭呼肠孤病毒感染的病理特征,地域性特点,运用病理剖检、常规石蜡切片及HE染色、免疫组织化学等技术对鸭呼肠孤病毒自然感染病鸭进行研究。剖检眼观病变表现为肝、脾表面出现大量黄白色病灶,组织学病变为肝、脾出血、坏死与肉芽肿形成,免疫组织化学检测结果显示所感染病鸭脾均出现特异性阳性信号,而肝和法氏囊仅部分出现阳性信号。由以上结果推测可知湖北省鸭呼肠孤病毒感染特征表现为肝脾坏死。

Abstract:

The aim of this study was to understand the pathological characteristics of duck reovirus naturally infection in Hubei province.Pathologic autopsy,HE staining,and the immunohistochemical analysis were used to study the ducks naturally infected with duck reovirus.Results were as follows:At necropsy,large yellowish-white necrotic foci were observed in the spleens and livers.By histopathology,hemorrhagic,necrotic lesions and granulomas were seen in both organs.Immunohistochemical detection showed that all spleen samples had positive signals,but in liver and bursa only part of the samples were positive.Taken together,our results reveal that the liver and spleen necrosis is the characteristics of duck reovirus infection in Hubei province.
