Biochemical Characterization of Bovine Leukemia Virus
2015The 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, 1981SUMMARY 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, 2014Phylogenetic 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 ...

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

No Involvement of Bovine Leukemia Virus in Sporadic Bovine Lymphosarcoma
Microbiology and Immunology, 1986AbstractUsing 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.

Identification of a new genotype of bovine leukemia virus
Archives of Virology, 2012To 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

Bovine Leukemia Virus Infections
American Association of Bovine Practitioners Conference Proceedings, 1984With the obvious reservation that new findings may, at any time, alter our concepts regarding Bovine Leukemia Virus (BLV) infections, the current status of our knowledge leads to the conclusion that, except for the frank neoplastic disease and the restrictions on international trade, BLV does not play an important role in cattle disease and has no ...

The zoonotic potential of bovine leukemia virus
Veterinary Research Communications, 1981Many workers have investigated the possibility that bovine leukemia virus (BLV) might be transmissible to man. The epidemiological studies were designed to examine for associations between human leukemia and a rural environment, cattle farming, veterinary activities, or bovine leukosis. The serological studies were used to test serum samples from human

Economics of Bovine Leukemia Virus Infection
Veterinary Clinics of North America: Food Animal Practice, 1997A herd infected with bovine leukemia virus suffers a direct economic loss due to clinical lymphosarcoma. A major indirect cost associated with infection is restriction of the sale of animals and germplasma to foreign markets. Reports on the economic effects of infection on production have been variable and are reviewed in this article.

Bovine Leukemia Virus in Bovine Aborted Fetuses
Journal of Leukemia, 2019We investigated the infection of Bovine Leukemia Virus (BLV) related to other pathogens [Neospora caninum, Bovine Herpesvirus-1 (BoHV-1), Bovine Viral Diarrhea Virus (BVDV), and pathogenic bacteria] in 80 bovine aborted fetuses. The materials comprised whole fetuses, fetal organs, and placenta.
