Following infection with M. bejeranoi, proteins related to the fish immune system were increased, most prominently Scavenger Receptor Cysteine-Rich (SRCR) domain-containing protein (m130/cd163) (fold change 6.12) and pentraxin 3 (fold change 4.38) (Figure 3, Supplementary Table S1). The gene discussed is PTX3; the disease is infection.
