Detection and Identification of Enzootic Bovine Leukosis (EBL) in Calves in Iran

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...

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...

Role of colostrum and milk in the natural transmission of the bovine leukemia virus.

The role of colostrum and milk in the transmission of the bovine leukemia virus (BLV) was examined by monitoring the development of BLV infection in calves that were fed since birth on colostrum and milk from their BLV-positive dams and then reared in complete or partial isolation from infected cattle. Twenty-one of the 25 calves raised in complete isolation remained negative for BLV until the ...
