Five groups of 4-week-old turkey poults were each infected by aerosol with a different lentogenic strain of Newcastle disease virus. Four days postinfection, sections of tracheas were collected for histopathologic characterization and virus titration. The most prominent lesions were fibrinopurulent exudate in tracheal lumens, hyperplasia of epithelial cells, and infiltration by lymphocytes. All strains multiplied to high titers and produced similar microscopic lesions, but the number of poults with severe microscopic lesions varied among groups.
将五组4周龄的小火鸡通过气溶胶感染不同的新城疫病毒弱毒株。感染后4天，收集气管切片进行组织病理学特征分析和病毒滴定。最显著的病变是气管腔内的纤维蛋白脓性渗出物、上皮细胞增生和淋巴细胞浸润。所有毒株均增殖至高滴度并产生相似的微观病变，但有严重微观病变的小火鸡数量在各组之间有所不同。
