FIG 5.

Quantification of CSFV loads in tonsils and retropharyngeal lymph nodes following C-strain vaccination and/or virulent Brescia challenge. The tonsils and retropharyngeal lymph nodes were collected longitudinally following C-strain vaccination and challenge 5 days later with CSFV Brescia strain. CSFV RNA loads were quantified in the tissues by qRT-PCR. The data represent the mean of 3 pigs/group ± SEM. Statistical analyses were performed using a one-way ANOVA, followed by Bonferroni's multiple comparison test: **, P < 0.01.
