FIG. 2.

Analysis of anti-S protein MAb for inhibition of viral recrudescence. N⁺, neutralizing; F⁺, fusion inhibiting. Ab was transferred i.p. on days 9, 12, and 17 p.i., and virus was assayed at 21 days p.i. Control groups were treated with PBS only. Virus titers in recipients of N⁺ anti-S protein MAb (A), N⁻ anti-S protein MAb (B), and N⁻ anti-M and anti-N protein MAb (C). Error bars indicate standard errors of the means. The dashed line indicates the limit of viral detection. *, P < 0.05. Survival rate and number of mice per group are shown on the right. Data represent the average of at least three separate experiments with four or more mice per group.
