the objective of this study was to compare an indirect elisa, based on a purified 60 kda envelope glycoprotein (gp51su), with a pourquire indirect elisa for the detection of antibodies to the bovine leukemia virus. for conducting this research, 340 serum samples were collected from two different breeds of cows (sarabi and holestin) in different herds. commercial elisa revealed positive results ...

the purpose of this study was to determine the prevalence of bovine leukemia virus (blv) in khorasan razavi and khorasan shomali provinces which are the main provinces located in the northeast of iran. total number of 429 blood samples were collected from industrial dairy herds. the samples were categorized based on province, age (2-3, 4-6, and 7-10 years old), calving (≤ 2, 3-5, and > 5) and h...

Short term cultures of bovine leukemic lymphocytes release virus particles with biochemical properties of RNA oncogenic viruses. These particles, tentatively called Bovine Leukemia Virus (BLV) have a high molecular weight-reverse transcriptase complex and a density averaging 1.155 g/ml in sucrose solutions. Molecular hybridizations between BLV-3H cDNA and several viral RNAs show that BLV is not...

Enzootic bovine leukosis (EBL) is known as bovine lymphosarcoma and normally affects the old cattle. EBL is caused by bovine leukemia virus (BLV), which is generally spread all around the world. This virus is transmitted via bovine blood products within and between cattle herds. Glycoprotein GP51 in the blood is responsible for cattle immune responses to BLV. This virus has been previously dete...

In this study, 345 cattle from 7 herds with a history of lymphosarcoma were tested for antibody to BLV antigens by three serological methods, namely immunodiffusion using a bovine leukemia virus glycoprotein with a molecular weight of 60,000 as antigen, and radioimmunoassay using a bovine leukemia virus glycoprotein with a molecular weight of 60,000 and a bovine leukemia virus protein with a mo...

The results of examination of 375 bovine serum and 150 bovine milk samples for detection of bovine leukemia virus infection by the immunodiffusion technique were compared with those of an enzyme-linked immunosorbent assay (ELISA). It was concluded that the ELISA is another useful method for the detection of antibodies to bovine leukemia virus in serum and milk. The ELISA provides a quantitative...

bovine leukemia virus (blv) is a retrovirus causing a chronic leukemia/lymphoma in cattle in many countries around the world. screening for antibodies by elisa has been the primary means of detecting the presence of this virus. it is not yet known if this assay will detect antibodies in all cattle during a concomitant bovine leukemia virus infection. the polymerase chain reaction (pcr) of the t...
