Edwardsiella septicemia is a serious systemic bacterial infection caused by Edwardsiella piscicida/ tarda of the genus Edwardsiella and family Enterobacteriaceae.  A wide range of hosts, including freshwater, brackish water, and marine aquatic species, are susceptible to the bacterium that causes Edwardsiellosis, which results in significant financial losses for aquaculture globally.

Synonyms of disease: emphesematous putrefactive disease of catfish, red disease of eels, and Edwardsiella septicemia of salmon, tilapia, and striped bass.
