Heatmap visualization and hierarchical clustering of selected 30 differentially expressed genes. The heatmap displays selected 30 differentially expressed genes between Tetracapsuloides bryosalmonae-exposed and unexposed control brown trout posterior kidney selected based on adjusted P-value, sample and feature. Hierarchical clustering was performed using the single linkage method based on Euclidean distance matrix. Each column represents a posterior kidney sample and each row represents a gene
