  1. aVirus titers were determined by the XC overlay test as in Table 1. Titers represent the number of XC PFU in 0.2 ml and were done in triplicate. Bold figures represent titers reduced by more than 95% (1.3 log10) relative to titers in susceptible NIH 3T3 or M. dunni cells.
  2. bCAT-1 gene expressed in transfected cells is given in ().
  3. cSyncytia were observed 2 days after virus infection.
