Evaluation of syncytium assay for bovine leukemia virus.

摘要: As a new method for the detection of bovine leukemia virus (BLV) infection, syncytium assay was evaluated with lymphocytes from infected cattle and sheep. Only when enzootic leukosis sheep experimentally BLV were used, formation induced among indicator cells. A direct proportional dose response presented by number inoculated BLV-infected to syncytia formed. Treatment an adult form lymphosarcoma anti-BLV serum could inhibit formation, but neither antiserum against syncytial nor sera sporadic inhibit. These results indicate specificity usefulness this infection.
