Endogenous viral genes influence infection with avian leukosis virus

Exogenous and Endogenous Leukosis Virus Genes

Avian Leukosis Virus

Ultrastructural studies of chick embryo cells morphological ly altered by strain MC29 avian leukosis virus revealed marked and characteristic differences from normal cells and cells al tered by infection with other avian tumor viruses. Such differ ences were manifest in part in the cytoplasm by high content of free ribosomes, poorly developed rough endoplasmic reticu lum, frequent fat droplets,...

Infection and Tumor Formation in Chickens By Avian Leukosis Virus

Lymphoid leukosis in chickens is a disease which arises from the result of complicated interaction between avian leukosis virus (ALV) as a pathogenic organism and chicken as a host. This report is intended to outline our present knowledge about genetic resistance of chickens in lymphoid leukosis. The defense of host in infectious disease could be considered dividing it into two: one as a workin...

Lack of evidence of endogenous avian leukosis virus and endogenous avian retrovirus transmission to measles, mumps, and rubella vaccine recipients.

The identification of endogenous avian leukosis virus (ALV) and endogenous avian retrovirus (EAV) in chick cell-derived measles and mumps vaccines in current use has raised concern about transmission of these retroviruses to vaccine recipients. We used serologic and molecular methods to analyze specimens from 206 recipients of measles, mumps, and rubella (MMR) vaccine for evidence of infection ...
