ConclusionComparisons of SD07LK1 sequence with that of the other Avian leukosis viruse strains, by using DNAstar software, demonstrated that the genes gag and pol of ALV-J were relatively conservative, the nucleotide identity of all the strains was over 95.0%. However, the gene env identity was only in the ranges between 88.6 and 94.0%.

To determine the extent of avian leukosis virus infection in China in 2009, 178 suspected ALV samples were collected from 39 chicken farms in eight provinces and examined by polymerase chain reaction with ALV-A, ALV-B and ALV-J gene specific primers.

为了解自2009年年初以来国内一些地区禽白血病流行情况及流行毒株的分子特征，我们从湖北、黑龙江、山东、辽宁、吉林、广东、宁夏、安徽8个省区39个鸡场采集疑似禽白血病病料样品178份，用ALV-A、ALV-B和ALV-J特异性引物，通过PCR方法进行检测。

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。
