J亚群禽白血病病毒（Subgroup J of Avian leukosis virus，ALV-J）是90年代初由英国鉴定出来的禽白血病病毒新的亚群，主要引起肉鸡的骨髓瘤白血病。

An subgroup J avian leukosis virus,designated as SCAU-0901,was isolated and identified by histopathological observation,DF-1 cell culture,ELISA test,PCR and immunofluorescence assay specific to ALV-J from Mahuang broiler breeder suspected with ALV infection.

在组织病理学观察的基础上，经接种DF-1细胞系、ELISA抗原检测、聚合酶链式反应以及亚群特异性免疫荧光试验，从送检的疑似禽白血病感染的麻黄肉种鸡中分离并鉴定出1株J亚群禽白血病病毒，命名为SCAU-0901。

Twenty two bird species were observed feeding on plant fruits or seeds in the botanical garden, among them, Turdus merula, Pycnonotus sinensis, Cyanopica cyana, Streptopelia orientalis, Urocissa erythrorhyncha and Pica pica were main avian frugivores according to the number of plant species they eated.
