FIG 6.

Temperature and weight changes following i.p. inoculation with EIII chimeras. Groups of five 3- to 4-week-old female Swiss Webster mice were infected with 100 PFU of WNV NY99 or an EIII chimera via the i.p. route. Temperatures (A) and weights (B) were measured daily for 21 days following infection. Three different weight profiles emerged: one for the WNV NY99- and WNV/JEV-EIII-infected mice (Bi), a second one for the WNV/KOUV-EIII- and WNV/SLEV-EIII-infected mice (Bii), and a third for the WNV/BAGV-EIII-infected mice (Biii).
