Genetics of Leukemogenesis by Avian Leukosis Viruses
1981Oncoviruses of chickens can be classified into one of three groups, depending on their effects on cells in culture and their pathogenicity and lifestyle in the chicken (Fig. 1). The most intensely studied but rarest of these viruses are the transforming acute leukemia and sarcoma viruses.

Contact Transmission of Avian Leukosis Virus2
JNCI: Journal of the National Cancer Institute, 1977Intravenous 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.

On the Terminology and Classification of the Avian Leukosis Complex
Avian Diseases, 1967Recent advances in studies of the causes and pathogenesis of a group of neoplasms heretofore known as the avian leukosis complex have provoked a reconsideration of established terms and classifications. Several classifications (1,2,5,6,7,10), each a product and a contribution of its time, have been published in the literature.

Ribosomal rna in avian leukosis virus particles [PDF]
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
1986Infection 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).

Avian Lymphoid Leukosis: Mechanisms of Lymphomagenesis
1988Publisher Summary This chapter discusses the factors responsible for the progression of the neoplastic condition through each stage in the ontogeny of lymphoid leukosis (LL), namely, infection, hyperplastic transformation, bursal lymphoma development, and metastasis to visceral organs.

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 ...

Isolation and identification of avian leukosis viruses: A review [PDF]
Avian Pathology, 2000 Avian 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
