Viral titer (log
/g) in pooled spleen-heart of sampled animals from the L15 + VHSV and poly I:C + VHSV groups. (P) animals inoculated with the pathogenic VHSV isolate. (NP) animals inoculated with the non-pathogenic VHSV isolate. Bars indicate mean ± standard deviation (SD) obtained from three different samples. Different letters denote significant differences (p < 0.05) between groups at each sampling times and within the same group throughout the time.
