FIG. 2.
Assessment of mean body weight. CBA mice in groups of five were weighed immediately prior to i.n. infection with 4 × 105 PFU of EHV-1 KyA, EHV-1 recombinant KyARgp2F, or wild-type pathogenic RacL11 and weighed each subsequent day through day 3. Each data point shown represents the mean body weight for the indicated group at that particular time point, with error bars indicating the standard deviations from the means. *, the experiment was terminated at day 3 due to the physical condition of KyARgp2F- and RacL11-infected mice to prevent undue suffering.
