  1. For a description of score criteria, see Table 1. Hearts from five fish were sampled from each group at each time point. No lesions could be seen in control fish, except for small foci with epicarditis in 11 out of 43 control fish (25.6%). The percentage of fish with PD-specific lesions (≥2) at each time point is given, and also the mean lesion score with standard deviation given in parenthesis. SNorm = SAV-infected, normal oxygen conditions. SRed = SAV-infected, reduced oxygen conditions. ND = no data.
