Bovine leukemia virus

The Bovine Practitioner, 1979
Although BLV antigens have been detected in the urine of infected cows, infectious BLV has not been detected, and attempts to transmit the virus by inoculation of urine into susceptible recipients have failed. Neither BLV nor its antigens have been detected in saliva or semen, and neither secretion has been implicated in the natural transmission of the

Evidence in support of a virus etiology for bovine leukemia [PDF]

Cancer, 1967
Virus-like particles resembling the C-type particles of murine leukemia were detected in tissue biopsies and more frequently in thin sections of pellets following density gradient centrifugation of milk from leukemic cows and cows in a high incidence leukemic herd. These particles had a buoyant density in potassium citrate and sucrose gradients of 1.15

Morphogenesis of bovine leukemia virus

Virology, 1977
Abstract The morphogenesis of bovine leukemia virus (BLV) was studied in short-term cultures of leukocytes from cows with persistent lymphocytosis and in BLV-producing cell lines. Few budding particles were found. They consisted of one shell underneath the cell membrane with granules attached to the inner side. When the shell is completed the budding

Leukemogenesis by Bovine Leukemia Virus [PDF]

, 1983
Bovine leukemia virus (BLV) is a type C retrovirus which is the causative agent of a B cell lymphocytic leukemia horizontally transmitted in cattle (1, 2, 3). This virus was proven to be totally exogenous to its target animal as well as to sheep, goat, mouse, cat, chicken and man (4).

Bovine Leukemia Virus

1994
In bovine pathology, research performed between 1871 and 1877 by Siedam-grotzky was apparently the first attempt to study bovine leukosis (BL) and characterize it as a clinical entity. At the beginning of the 20th century, pathologists interested in this disease observed that BL is a herd disease of probable infectious origin.

Biochemical Characterization of Bovine Leukemia Virus

2015
The authors conclude that BLV is a bovine RNA oncogenic virus, probably exogenous with practically no relatedness to presently known leukemia viruses. Infected animals synthesize antibodies against the main low molecular weight protein of the virus p 24.

Genotypic identification of the bovine leukemia virus

Molecular Genetics, Microbiology and Virology, 2014
Phylogenetic analysis of the sequenced segments of the provirus BLV locus env-gene and the strategy of the PCR-PDRF-genotyping consistent with phylogenetic classification of pathogenic agent and suggested in our works provided taxonomic identification of BLV isolates identified in cattle in Tatarstan (Russian Federation) as representatives of the 4th ...

In vivo transcription of bovine leukemia virus and bovine immunodeficiency-like virus

Virus Research, 2003
Cellular tropism and transcription of bovine leukemia virus (BLV) and bovine immunodeficiency-like virus (BIV) were investigated using peripheral blood mononuclear cells (PBMC) collected from a cow infected with both viruses. Each PBMC subset, purified by magnetic cell sorting, was subjected to PCR and RT-PCR for detection of their integrated ...
