Dengue vesicles were less likely to be neutralized by convalescent dengue serum.
PRNT assays were performed in parallel as described in the Methods section. (a) Dengue vesicles derived from freshly infected HBM were less likely to be neutralized by the same dengue patient serum in comparison with laboratory dengue virus derived from Vero cells. (b) PRNT50 was defined as the serum dilution factor that could inhibit 50% of the input virus. The PRNT50s from the samples used in (a) were compared and found to be different (p = 0.031).
