Fig. 3. Normalised expression of ISA virus RNA against the exogenous control, SAV, in gill and heart tissue. Each bar in the figure represents the normalised Ct-values that were converted
into -fold change and then Log2 transformed. The gill sampleswere collected prior to decomposition. After 96–120 h with decomposition, the gill samples could not be retrieved, thus heart
tissue was sampled instead. The heart samples were from 96 (F3–F10) and 120 (F1 and F2) hours with decomposition.
