Pathological changes observed in post-smolt Atlantic salmon i.p. challenged with P. salmonis LF-89-like isolate (Psal-013), EM-90-like isolate (Psal-182) or after co-infection with both isolates (ratio 1:1). The intensity of colour shows the frequency as a percentage (%) of the sampled fish with the pathological signs listed at 14 and 21 days post-challenge (dpc). 100% corresponds to n = 12.
