K-means analysis separating the 129 discriminant proteins into four clusters based on expression level in the different groups (Z-score). Different colours indicate different clusters, with blue indicating cluster A (n = 20), yellow indicating cluster B (n = 46), violet indicating cluster C (n = 41) and green indicating cluster D (n = 22). Group means are represented for clarity. C, control (uninfected) fish; H, fish with high degree of infection; M/L, fish with medium/low degree of infection
