Pathogenicity of Two Recombinant Avian Leukosis Viruses
Avian Diseases, 2003We have recently described the isolation and molecular characteristics of two recombinant avian leukosis subgroup J viruses (ALV J) with an avian leukosis virus subgroup A envelope (r5701A and r6803A). In the present study, we examined the role of the subgroup A envelope in the pathogenesis of these recombinant viruses.

Characterization of Monoclonal Antibodies to Avian Leukosis Viruses
Avian Diseases, 1986Hybridoma cell lines secreting monoclonal antibody (MCA) to avian leukosis virus (ALV) structural proteins p27 and p19 have been established. In an indirect enzyme-linked immunosorbent assay (ELISA), MCA 6AL20 (IgG1 isotype) reacted with RPL-40 (ALV subgroup A), avian myeloblastosis virus (AMV) (a mixture of subgroups A and B), Rous-associated virus ...

Endogenous leukosis viruses in the avian family phasianidae
Virology, 1977Abstract Helper virus. activity for the defective Bryan high titer strain of Rous sarcoma virus (RSV) has been found in normal embryo fibroblast cultures of Ghighi, green, Mongolian, silver, and Swinhoe pheasants, and of Chinese quail and chukar. The helper viruses from Chinese quail and from Swinhoe pheasant were isolated from their respective RSV ...

Use of Lactic Dehydrogenase for Detection of Avian Leukosis
Nature, 1964IN the United States, the loss of birds from the avian leukosis complex is of the order of 1,000,000 dollars per week1. The loss to the poultry industry in the United Kingdom is estimated to be about £7,500,000 annually2. Investigation and control of the disease are impeded by lack of a rapid, dependable diagnostic test. The resistance-inducing factor (

Target Cells for Transformation with Avian Leukosis Viruses
1976Leukemia is a widespread disorder of the hemopoietic system of vertebrates which has been particularly well analyzed in chickens, mice and recently also in cats (for review see 1). It seems now safe to assume that the majority of the different ypes of leukemias found in animals are caused by infection with or activation of C-type leukemia viruses (1 ...

Progression of Avian Lymphoid Leukosis
1989The leukosis/sarcoma viruses, members of the avian oncornavirus or oncovirus group, cause a wide spectrum of tumors in chickens. The most common under field conditions is lymphoid leukosis, a B-cell lymphoma. In susceptible chickens infected at an early age, cells of the cortex of the bursa of Fabricius of 6- to 8-week-old chickens transform and ...

Isolation and identification of avian leukosis viruses: A review
Avian Pathology, 2000Avian leukosis virus (ALV) is the most common naturally occurring avian retrovirus that can cause a variety of neoplastic disease conditions in chickens. In addition to causing neoplasia, ALV is known to be associated with reduced productivity and other production problems in affected flocks. Biological and molecular assays for the detection of ALV are

Developments in avian leukosis research.
Leukemia, 1992Infection by exogenous avian leukosis viruses (ALVs) causes economic loss from neoplastic mortality and from impaired performance of subclinically infected chickens. This paper reviews progress in research related to natural infection and its control.
