Avian leukosis virus (ALV) is one of causing agents for neoplastic syndrome in commercial chicken farms. There are six sub groups of ALV in chicken including A, B, C, D and E. However, the sub group J (ALV-J) is the most alarmed and anticipated because of its severe economic repercussion. The objective of this study was to identify the presence of ALV-J in the commercial chicken farms in Tangerang District. Two identification methods were utilized including antigen capture enzyme-linked immunosorbent assay (ac-ELISA) technique and nested reverse transcriptase polymerase chain reaction (nRT-PCR) test. As results, the ac-ELISA test detected that most of 150 serum samples from 5 commercial layer farms were positive for ALV in about 86,67%. On the other hand, none of the 60 cloacal swab and 60 albumen samples was positive for presence ALV. Subsequently, testing of 45 serum samples from 5 farms using nRT-PCR showed that in about 20% of these samples were positive of ALV-J. These evidences indicated the circulation of ALV-J with other sub groups in the
commercial layer farms in Tangerang District.
