Effect of F C on PV-2 replication cycle. A. Kinetics of PV-2 extracellular production during one replication cycle Vero cell monolayers were infected with PV-2 ( m.o.i. = 10). Viral titers were determined at different hours by plaque assay. B. Effect of addition of FC on the PV-2 production during a one step replication cycle At different h p.i. after the adsorption period, FC (22 μg/ml) was added and the extracellular viral production was determined at 10 h p.i. of incubation at 37°C, by the plaque assay. Data represent % of virus production respect to untreated control. The viral production at 10 h p.i. in the kinetic curve of control virus was considered 100%. * p < 0.05 vs 0 and vs 2 h (one-way ANOVA with Bonferroni a posteriori test).
