Figure 2. Mean viremia profile (red lines) and mean hemagglutination inhibition (HI) antibody profile (blue lines) of 5 species of wild rodents after experimental infection with 3 log10 PFU of Venezuelan equine encephalitis virus type-IE, strain MX01-22. Black dashed lines indicate approximate mosquito infection viremia threshold for the enzootic vector Culex (Melanoconion) taeniopus. Fractions represent proportion of total cohort that had measurable response. Data for days 42 and 66 (not shown) did not differ significantly from data for day 28. Error bars indicate SEM.
