Mean normalized expression (MNE) of Parvicapsula pseudobranchicola small subunit rRNA in samples from blood, gills, heart, kidney and liver of Atlantic salmon collected during the study period. MNE is highly concordant days 21–216 (all samples), and days 21–601 (gills, heart, kidney). Note that the vertical scales differ, and that the MNE values are not directly comparable across tissues. Asterisks (*): very low NE; columns present but invisible, ‘ns’, no sample
