FIG 8.
The SBVp32 glycoprotein is more infectious than the wild-type SBV glycoprotein. CPT-tert cells were infected with 2.5 × 105 genome equivalents of the indicated viruses, and the number of SBV-positive cells was counted at 8 h postinfection after immune staining. Ten view fields were counted under each condition. The percentage of positive cells is presented relative to that of wild-type SBV infection. The experiment was repeated 3 times independently. Data were analyzed by using analysis of variance (P = 0.0076).
