FIG. 1.

Kinetics of SFV-2 virus replication in different cell lines. SFV-2 virus replication was monitored at various time points p.i. of M. dunni cells, Cf2Th cells, HeLa cells, and Vero cells. Filtered supernatant was assayed in two independent RT assays. Each sample was spotted in duplicate. The means ± SDs (error bars) for each infected culture (□, ■) and the uninoculated control cells (○) are shown. The progression of cytopathogenicity is indicated, ranging from no CPE (−) to about 90% CPE (4+).
