Abstract
Abstract:A strain of Avian leukosis virus(ALV.J1 subgroup J was isolated from an adult broiler
breeder folck.which had a history of myeloid leukosis(ML).in Inner Mongolian.Moreover,another
strain of ALV J was isolated from a ML case in Shandong.The two isolates were positive reaction in
polymerase chain reactions with two pairs of primers specific for ALV-J and gave antigenically strong
reaction in the indirect fluorescence antibody assay(IFA)with ALV-J specific monoclonal antibody JE9.
The sequences of the 2.2kb PCR products of the tWO strains had 96.9% homology,an d had 94.2%
— 95.4% homology to strain SD9901 and YZ9901 AL\LJ.
