(a) Mean virus load and expression of transcripts encoding the viral P4a capsid core protein in a tissue library of KSD-affected fish showing that gills are the main target organ for the virus. Colors indicate different levels of virus load: orange 10⁷ copies – 10⁵ copies, green 10⁵ copies - 10⁴ copies, blue 10⁴ copies – 10³ copies, grey <10³. (b) Box plot diagrams presenting 25%–75% (±minimum and maximum values) percentiles and the median as a horizontal line of the virus load in analyzed carp tissues. Depicted is the copy number of viral genome per 250 ng of isolated DNA from n = 5 specimen. (c) Box plot diagrams presenting 25%–75% (±minimum and maximum values) percentiles and the median as a horizontal line of data on the expression of mRNA encoding the viral P4a capsid core protein in normalized copy numbers in analyzed tissues from n = 5 specimen
