Studies on Bovine Leukosis

Studies on Fowl Leukosis

Following the observations on high-speed centrifugation of the avian sarcoma agent by various investigators,1' 8,10,11,12 similar studies of the agent of fowl leukosis have been undertaken. Since the neoplastic nature of this disease is now rather generally recognized, observations on the filterable agent of chicken leukosis have assumed new significance for the study of the etiology of fowl ne...

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 (...

Enzootic 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...

Bovine 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...
