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 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.

Inhibition of Bovine Leukemia Virus Release 2

JNCI: Journal of the National Cancer Institute, 1975
Sera from 3 cows with the adult form of lymphosarcoma inhibited release of leukemia virus from a cell line of fetal lamb spleen infected with bovine leukemia virus (BLV). Sera from 5 to 7 cattle experimentally infected with BLV also suppressed virus release. The inhibition of virus release was reversible.

The zoonotic potential of bovine leukemia virus

Veterinary Research Communications, 1981
Many 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

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

Economics of Bovine Leukemia Virus Infection

Veterinary Clinics of North America: Food Animal Practice, 1997
A 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.

Biochemical features of bovine leukemia virus

Veterinary Microbiology, 1976
Abstract Short term cultures of bovine leukemic lymphocytes (enzootic form of the disease) release virus particles with biochemical properties of RNA oncogenic viruses. These particles, called Bovine Leukemia Virus (BLV), are never produced by normal lymphocytes.

Serological investigations on bovine leukemia virus

Veterinary Microbiology, 1976
Abstract A complement fixation test was developed to investigate the presence of antibodies to the bovine leukemia virus. For 226 animals from 13 different herds it was possible to correlate the results of the serological test and the white blood picture, where the criteria established by the commission of the European communities were used.

Bovine Leukemia Virus Infections

American Association of Bovine Practitioners Conference Proceedings, 1984
With 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 ...

Immunological implications of bovine leukemia virus infection

Research in Veterinary Science, 2017
This study examined neutrophil and monocyte functions and the blood lymphocyte profile of naturally BLV-infected cows with or without persistent lymphocytosis (PL). The percentage of neutrophils and monocytes that phagocytosed Staphylococcus aureus was lower in BLV-infected dairy cows, particularly those with PL.
