Dynamics of perinatal bovine leukemia virus infection
BACKGROUND Bovine leukemia virus (BLV) is highly endemic in many countries, including Argentina. As prevention of the spread from infected animals is of primary importance in breaking the cycle of BLV transmission, it is important to know the pathophysiology of BLV infection in young animals, as they are the main source of animal movement. In this work, we determined the proviral load and antib...

متن کاملdetection of bovine leukemia virus infection by nested-pcr analysis
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...
متن کاملFetal infection with bovine leukemia virus in sheep.
Several sheep fetuses were thymectomized, and their tails were removed at 58 to 65 days of gestation for tissue culture. Bovine leukemia virus (BLV) antigens were detected in serial culture of tissues from fetuses whose dams and sires were both BLV positive. However, no BLV antigens were detected in serial cultures of tissues from fetuses whose dams were negative but whose sire was positive. Pr...
