The result of antiviral experiment. Five different virus titers from 101 TCID50 to 105 TCID50 per 0.1 ml of ALV-B were inoculated per well in 24-well cell culture plates containing 1 mL 1.7 × 105cells/well DF-1/B cells in triplicate. (A) ALV-B (CD08) replication was inhibited in DF-1/B, but not DF-1 cells. (B) Replication of ALV-J (CHN06) was not inhibited in either DF-1/B or DF-1 cells. (C) Infection by clinically isolated unidentified subgroups ALV, one of them was blocked in DF-1/B, but not in DF-1cells. In A–C, viral p27 protein levels determined by ELISA were reported. Black lines mean S/P = 0.2.
