Early syncytium formation by bovine leukemia virus.
Bovine leukemia virus (BLV) from either persistently infected bat cells or fetal lamb kidney cells induced rapid syncytium formation in F81 indicator cells. Distinct syncytia were seen within 2 h after inoculation of cells with highly concentrated (500-fold) cell-free BLV preparations and within 4 to 8 h when unconcentrated cell-free BLV preparations were used. Indicator cell densities of 1 x 1...
متن کاملBovine leukemia virus gene expression in vivo.
The in vivo transcriptional status of bovine leukemia virus was assessed at three stages of infection during the progression of the disease: aleukemic stage, persistent lymphocytosis, and leukemia/lymphosarcoma. Bovine leukemia virus transcripts could be amplified from total or cytoplasmic enriched lymphocyte RNA by reverse transcription polymerase chain reaction in cells from all but a few ale...
متن کاملDetection of Antibodies Against Bovine Leukemia Virus
A modified syncytium-induction inhibition test which is more sensitive than the immunodiffusion test, was developed using rabbit complement. In this test, fetal lamb kidney cells continuously infected with bovine leukemia virus were used as effector cells, and the CC81 cat cells transformed with murine sarcoma virus, were used as indicator cells. The syncytiuminduction inhibition effect of anti...
متن کاملDynamics 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 کاملBovine leukemia virus: an exogenous RNA oncogenic virus?
Short term cultures of bovine leukemic lymphocytes release virus particles with biochemical properties of RNA oncogenic viruses. These particles, tentatively called Bovine Leukemia Virus (BLV) have a high molecular weight-reverse transcriptase complex and a density averaging 1.155 g/ml in sucrose solutions. Molecular hybridizations between BLV-3H cDNA and several viral RNAs show that BLV is not...
