DENV titers ^a (x10 ⁶ pfu ^b /ml) in the absence and presence of MB21

DENV serotype c	Without MB21	With MB21 d	P value e
1	1.06 ± 0.03	0.52 ± 0.02	0.0028***
2	1.54 ± 0.12	0.27 ± 0.01	0.0045***
3	0.59 ± 0.01	0.14 ± 0.04	0.0065***
4	0.22 ± 0.02	0.05 ± 0.03	0.031**

^aTiters were determined by plaque assay on Vero cells.

^bPfu = plaque forming units.

^cThe viral strains used were: DENV-1: West Pac 74; DENV-2: S-16803; DENV-3: CH54389; and DENV-4: TVP-360.

^dMB21 used at 30 μM final concentration.

^e P values were calculated using Graphpad software; P values were either significant (**) or very significant (***).
