Bovine leukemia virus

, 2016
Bovine leukosis (lymphosarcoma, leukemia, or lymphoma) is one of the most frequent neoplastic diseases of cattle. Two types of bovine leukosis are recognized on the basis of their epidemiology: enzootic bovine leukosis and sporadic bovine leukosis. The enzootic form, which is caused by bovine leukemia virus (BLV), is the most frequent.

Genetic Determinants of Bovine Leukemia Virus Pathogenesis

AIDS Research and Human Retroviruses, 2000
The understanding of HTLV-induced disease is hampered by the lack of a suitable animal model allowing the study of both viral replication and leukemogenesis in vivo. Although valuable information has been obtained in different species, such as rabbits, mice, rats, and monkeys, none of these systems was able to conciliate topics as different as viral ...

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

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.

In Utero Transmission of Bovine Leukemia Virus

American Journal of Veterinary Research, 1981
SUMMARY In an initial study, 18 calves born to cows persistently infected with bovine leukemia virus (blv) were tested for infective virus and antibodies at birth, and no infected or seropositive animals were found. Four of these calves were maintained in quarters where infected animals were housed, and 3 of the 4 subsequently became infected.

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 ...

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
