Identification of a new genotype of bovine leukemia virus

Archives of Virology, 2012
To investigate the degree of genetic variability of bovine leukemia virus (BLV) strains circulating in Croatia, 29 isolates from the six largest dairy farms were examined by PCR for a segment of the gp51 env gene, followed by DNA sequencing and phylogenetic analysis. The nucleotide sequences were compared with other previously characterized BLV strains

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 ...

No Involvement of Bovine Leukemia Virus in Sporadic Bovine Lymphosarcoma

Microbiology and Immunology, 1986
AbstractUsing various portions of a molecularly cloned bovine leukemia virus (BLV) DNA as probes, the possible integration of a BLV genome or a BLV‐related sequence into the chromosomal DNA of sporadic bovine leukosis (SBL) tumor cells was investigated by Southern blotting analysis.

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 ...

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 ...
