Virulence of parental rVHSVmi, rVHSVdk and chimeric rVHSVs in juvenile rainbow trout. Juvenile rainbow trout were challenged, as described in Table 3, by intraperitoneal injection with parental rVHSVmi or rVHSVdk, chimeric viruses with reciprocal gene exchanges, wild-type MI03 or DK-3592B viruses, or mock-challenged with PBS. Experiments 1 (circles) and 2 (squares) tested exchanges of the G, NV, G and NV, or G and NV and L genes. Mortality of fish after challenge was recorded daily and expressed as the average cumulative percent mortality (CPM) for triplicate subgroups of 20 fish. Variation among subgroups is provided in Table 3. A) rVHSVmi series groups for experiments 1 and 2, B) rVHSVdk series groups for experiments 1 and 2
