An Immunohistological Study of Avian Lymphoid Leukosis

Avian lymphoid leukosis: Virus-like particles in kidney Cells

The epidemiology of avian lymphoid leukosis.

Avian lymphoid leukosis can be induced by lymphoid leukosis viruses belonging to Subgroups A, B, C, and D. The endogenous virus of the chicken (Rous-associated virus type 0) belongs to Subgroup E and has little, if any, potential for inducing lymphoid leukosis. Nearly all chicken flocks are infected with Subgroup A lymphoid leukosis virus. This virus can be transmitted from dam to offspring or ...

Endometrial lymphoid tissue: an immunohistological study.

Lymphoid tissue of the endometrium was analysed by histological, immunohistological, and electron microscopical methods in 10 healthy uteri. A panel of monoclonal antibodies recognising macrophages (OKMI), HLA-DR antigen, B lymphocytes, T lymphocytes and their subsets, and dendritic reticulum cells was used in a two stage indirect immunoperoxidase labelling technique. Endometrial lymphoid tissu...

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,...
