Detection and Characterization of Avian Leukosis Virus in Marek's Disease Vaccines
Avian Diseases, 2006Avian leukosis virus (ALV) infection in chickens is known to induce increased mortality, tumors, delayed growth, and suboptimal egg production. Countries importing specified pathogen-free eggs, vaccines, and poultry breeding stock require freedom of infection or contamination with ALV in such products among other avian pathogens.

Ribosomal rna in avian leukosis virus particles [PDF]
International Journal of Cancer, 1971 AbstractThe RNAs of avian viruses originating from the plasma of leukemic chickens (AMV) or from tissue culture (MAV‐B) consisted of five distinct components with sedimentation constants of 62 s, 27 s, 17 s, 9 s, and 4–5 s. Whereas the 27 s and 17 s minor RNA components could be consistently recovered from large quantities of AMV, fractionation ...

Characterization of an Avian Leukosis Virus Isolate
Avian Diseases, 1966An earlier publication reported the screening of hens from a commercial flock (Spring Lake Farms) for the purpose of selecting dams with which to establish a flock free of infection with agents possessing RIF (Resistance Inducing Factor) activity, i.e. the induction of cell resistance to Rous sarcoma virus (RSV) (6).

Contact Transmission of Avian Leukosis Virus2
JNCI: 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.

Restrictions That Influence Avian Leukosis Virus-Induced Lymphoid Leukosis
1986Infection of one day old White leghorn chicks with avian leukosis virus (ALV) usually results in the development of a bursal- dependent B-cell lymphoma (Purchase and Burmester, 1978). This tumor requires the bursal environment to develop and is characterized by the presence of cell surface immunoglobulin M (IgM) (Cooper et al., 1974).

An avian leukosis virus associated with stocks of rous sarcoma virus
Virology, 1962Abstract Isolation of a second virus from stocks of the Bryan high-titer strain of Rous sarcoma virus (RSV) is reported. The newly isolated agent, designated as Rous-associated virus (RAV), can be detected in tissue culture, despite its failure to produce discrete cytological alterations, because it interferes with infection and focus formation by ...

5′ avian leukosis virus sequences and osteopetrotic potential
Virology, 1992Recombinants of Rous-associated virus-0 and Br21 have been used to localize 5' viral sequences that affect the osteopetrotic potential of avian leukosis viruses. Rous-associated virus-0 is a benign subgroup E virus of endogenous origin that does not cause osteopetrosis. Br21 is a constructed subgroup E virus with high osteopetrotic potential.
