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.

Avian leukosis virus‐receptor interactions

Avian Pathology, 1998
Cellular 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 ...

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.

Serologic Survey of Man for Avian Leukosis Virus Infection

The Journal of Immunology, 1967
Summary Six current lots of 17 D yellow fever virus vaccine propagated in chicken embryos were found to be contaminated with complement-fixing group antigens of avian leukosis virus. Bloods of 111 individuals vaccinated with 22 different lots of the 17 D vaccine given up to 54 months before drawing a blood specimen were ...

Occurrence of subgroup J avian leukosis virus in Taiwan

Avian Pathology, 2002
There are three grandparent farms for three different chicken breeds in Taiwan. One of these farms, populated by breast meat yield chickens (yield type), suffered from a severe subgroup J avian leukosis virus (ALV-J) infection in mid-1997. The affected flocks at that farm had a weekly mortality of more than 1% and a 15% drop in egg production.

Host gene control of endogenous avian leukosis virus production

Virology, 1974
Abstract Chick embryo cell supernates or sera of young line 100 chickens, which were susceptible to avian leukosis-sarcoma viruses of subgroup E, contained large amounts of an avian leukosis virus. This virus had biological, chemical and physical properties identical with RAV-O, an endogenous subgroup E virus of the chicken. Line 100 cells homozygous

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 ...

Contact transmission of avian leukosis virus.

Journal of the National Cancer Institute, 1977
Intravenous 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.

Detection of avian leukosis virus: comparison of five techniques

Research in Veterinary Science, 1984
Five 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 ...
