5′ avian leukosis virus sequences and osteopetrotic potential

open access: yesVirology, 1992
Recombinants 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.

Characterization of an Avian Leukosis Virus Isolate

Avian Diseases, 1966
An 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).

Ribosomal rna in avian leukosis virus particles

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 ...

Restrictions That Influence Avian Leukosis Virus-Induced Lymphoid Leukosis

1986
Infection 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, 1962
Abstract 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 ...

Embryonic infection with the endogenous avian leukosis virus Rous-associated virus-0 alters responses to exogenous avian leukosis virus infection

Journal of Virology, 1987
We inoculated susceptible chicken embryos with the endogenous avian leukosis virus Rous-associated virus-0 (RAV-0) on day 6 of incubation. At 1 week after hatching, RAV-0-infected and control chickens were inoculated with either RAV-1 or RAV-2, exogenous viruses belonging to subgroups A and B, respectively.

Plaque assay for some strains of avian leukosis virus

Virology, 1972
Abstract Some strains of avian leukosis virus were found to produce plaques at 41 ° in cultures of chick embryo cells which had been fully infected with a temperature-sensitive mutant of Rous sarcoma virus (RSV) which fails to induce morphological transformation at the elevated temperature.
