FIG. 1.
Antibody prevalence among intact male and female rats inoculated with either 10−4, 10−3, 10−2, 102, 104, or 106 PFU of Seoul virus. Data are presented as percentages of individuals producing detectable antibody (i.e., adjusted average OD ≥ 0.100) against Seoul virus by day 40 postinoculation, with the fitted logistic regression curves for both males (solid line) and females (dashed line) included. Equal percentages of males and females seroconverted in response to each dose of Seoul virus (P > 0.05 in each case).
