CASP14 and infection: The identified transcripts involved in innate immune responses that showed positive (i.e., camp, casp14, ccl, cldn1, herc6, and rsad2) or negative (i.e., marco and clec4e) correlation with R. salmoninarum level (Supplementary Table S5) can be suggested as suitable biomarkers for assessing the infection level-dependent responses of Atlantic salmon to BKD.
