Figure 7From: DNA vaccines encoding the envelope protein of West Nile virus lineages 1 or 2 administered intramuscularly, via electroporation and with recombinant virus protein induce partial protection in large falcons (Falco spp.) Viremia of falcons during WNV lineage 1 challenge detected by qRT-PCR. The cycle threshold values (Ct values) of whole blood for all groups during the challenge period are displayed. In box-and-whisker plots the ends of the whiskers represent the minimum and maximum values, respectively. Outliers are represented as black dots instead of whisker-ends. The box includes 50% of the values of each group and median viremia value of each group is represented by a line in the middle. Vaccination groups with a statistically significant difference in the level of viremia in comparison to group E are labeled with an asterisk (ANOVA over all sampling days, p-values < α-levels of 0.05). There was no group with a statistically significant difference in duration of viremia (one-sided Wilcoxon rank sum test with continuity correction, cut-off Ct value 35.0, p-values < α-levels of 0.05).Back to article page
