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...

Sero-epidemiological studies of bovine leukaemia virus infection in Indian cross-bred zebu cattle

Antibodies against bovine leukaemia virus were detected in 322 of 1,511 serum samples from cattle of various age groups and both sexes, in various herds of the country. A variable degree (5.4 to 75%) of positive reactors was recorded in individual herds where no systematic breeding policy had been followed. Antibodies were also detected in clinically healthy cattle, having normal haematological...

Bovine Leukaemia Virus onco-protein Tax antigen identification in human lymphomas tissue

Background: Bovine leukaemia virus (BLV) is the primary cause of enzootic bovine leukaemia which belongs to the HTLV/BLV group of oncogenic retroviruses including Human T-cell leukaemia virus types 1, 2, and 3 and simian T-lymphotropic virus. Due to daily consumption of milk, meat and other dairy by-products, a possible role in appearing human cancers can be assumed for BLV. Materials and Metho...

Characterization of a colostrum replacer and a colostrum supplement containing IgG concentrate and growth factors.

The objective of this study was to characterize absorption of colostrum replacer (CR) or supplement (CS) containing fractions of bovine plasma. Immunoglobulin concentrate (IGC) was prepared from bovine blood to a final purity of approximately 90% IgG. Blood was also processed to produce a fraction containing elevated concentrations of IGF-I and TGF-beta (GF). Both IGC and GF were spray-dried an...
