The problem of the phage-like structure of the avian leukosis virus
Experientia, 1963Fur das Vorhandensein der spheroidalen und der phag-ahnlichen Form des Huhner-Leukosis-Virus (BAI, Stamm A) durfte das Stadium des Leukamieprozesses, metabolische Eigenschaften der Myeloblasten sowie deren Milieu verantwortlich sein.

Avian leukosis virus‐receptor interactions
Avian Pathology, 1998Cellular receptors for subgroups A, B, D and E avian leukosis virus (ALV) have been identified and characterized. The Tva receptor for subgroup A ALV is a member of the low density lipoprotein receptor family of proteins. There is an accumulating body of evidence to suggest that this receptor binds specifically to subgroup A viral envelope (Env ...

Detection of avian leukosis virus: comparison of five techniques
Research in Veterinary Science, 1984Five techniques were compared for their ability to detect decreasing dilutions of RAV-I, an avian leukosis sarcoma virus, in serially passaged chick embryo fibroblast cell cultures. The indirect fluorescent antibody test, sandwich enzyme-linked immunosorbent assay (ELISA) and reverse transcriptase assay were equally sensitive in detecting the virus ...

Myotropic Avian Leukosis Virus subgroup J Infection in a Chicken
Journal of Veterinary Medicine, Series B, 2006SummaryThe study describes a highly productive myotropic avian leukosis virus infection (ALV) in a 3‐month‐old female chicken. At necropsy, ascites, hepatic fibrosis and cardiomegaly were seen. Histologically, the most striking lesion was the presence of cytoplasmic basophilic inclusions in myocardial fibers.

Contact transmission of avian leukosis virus.
Journal of the National Cancer Institute, 1977Intravenous inoculation of four age groups of White Leghorn chicks with ALV-F42, a group A field strain of avian leukosis virus (ALV), indicated that persistent tolerant infection could be induced as late as 2 weeks post hatch, though most birds responded with neutralizing antibody.

Epizootiology of Avian Leukosis Virus Infections
1986This Chapter is concerned with the spread and survival of avian leukosis virus (ALV) in populations of domestic fowl, and the various factors which influence infection rate and incidence of disease. The term ALV as used here denotes the common “wild-type” exogenous avian retrovirus which causes mainly lymphoid leukosis (LL).

Immunology of Avian Leukosis Virus Infections
1986This Chapter will concentrate on three interactions of avian leukosis virus (ALV) with the immune system of the avian host. The first, neoplastic transformation of lymphoid cells, will be treated briefly and is the subject of more detailed discussion in Chapters 4 and 9 of this monograph.

Peripheral nerve sheath tumors (PNSTs) are rare in chickens and their etiology remains to be elucidated. In this study, a naturally occurring PNST in a Japanese native fowl (Gallus gallus domesticus) was pathologically examined and the strain of avian leukosis virus (ALV) isolated from the neoplasm was characterized by molecular biological analysis ...

We examined the effect of the presence or absence of endogenous viral gene (ev) 3, which controls expression of group-specific viral and envelope antigens (gs+chf+ phenotype), and ev2, which controls the production of a complete subgroup E virus (V-E+ phenotype), on the response of chickens to RAV-1, an exogenous avian leukosis virus (ALV) with an ...

Two strains of Avian leukosis virus subgroup B (ALV-B) were isolated for the first time in China Hy-line White on the cultured DF-1 cells which were inoculated tissue samples from by an ELISA assay, a histopathology examination and a PCR-based diagnosis.
