Abstract

Subgroup J Avian Leukosis Virus (ALV-J) was isolated in the late 1980s from meat-type chickens in the United Kingdom. This subgroup was created from recombination of exogenous and endogenous of avian leukosis viruses. ALV-J causes severe economic losses in meat-type chickens specially BROILER GRANDPARENT and broiler breeder flocks by inducing neoplastic diseases especially myeloid leukosis and other production problems. Samples of different tissues consisted of sternum, liver, kidney, spleen and preventriculus of 20 chickens from a flock which was positive to ALV-J in serological and molecular assays, were randomly collected for histopathological test. Histopathological examination revealed severe intercellular edema, anisocytosis, anisokaryosis, karyomegaly and intracytoplasmic inclusion bodies, similar to inclusion bodies of ALV-J in myocardium and scattered foci of myelocytes in liver of only 5 chickens. Therefore, the infection of a flock to ALV-J does not always induce gross or histpathological lesions.
