Enzootic Bovine Leukosis
Bovine Leukemia Virus (BLV) is the etiologic agent of Enzootic Bovine Leukosis, a retrovirus exogenous to the bovine species. Once infected, there is no detectable viraemia but instead there is a strong and persistent immunological response to BLV structural proteins, essentially the gp51 envelope glycoprotein and the mayor core protein p24. We describe the test procedure of an indirect ELISA (...
متن کاملEnzootic Bovine Leukosis
Both EBL and SBL occur in southern Africa and in the Southern African context it will therefore be very important to accurately differentiate between EBL and SBL. The epidemiology, direct and indirect economic impact, diagnosis and most importantly control and eradication of EBL is markedly different to that of SBL. Globally EBL infection may also place severe restrictions on the import and exp...

متن کاملBovine leukaemia virus and enzootic bovine leukosis.
Infection of bovines with bovine leukaemia virus (BLV) manifests itself in either of two ways: 30-70% of carriers develop persistent lymphocytosis (PL), with the viral genome integrated at a large number of different sites in the DNA of the affected B-lymphocytes, without causing any chromosomal abnormalities. Only 0,1-10% of carriers develop lymphoid tumours, which also consist of B-lymphocyte...
متن کاملProductive and reproductive performance in cattle infected with bovine leukosis virus.
Economic losses caused by enzootic bovine leukosis (EBL) have been of interest since World War II, when the neoplastic form of EBL increased dramatically in Europe. Olson (1974) and House et al. (1975) showed that animals with lymphosarcoma caused by the bovine leukosis virus (BLV) had reduced milk yields, a less efficient reproductive performance and high veterinary costs and mortality rates, ...
