→Introduction
''Edwardsiella tarda'' infects '''freshwater and marine fishes, reptiles and amphibians and mammals throughout the world'''. It causes '''''Edwardsiella septicemia (ES)''''' which is also known as '''''fish gangrene, emphysematous putrefactive disease of catfish or red disease in eels'''''. It causes serious systemic infection in cultured channel fish in the USA and in eels and flounders in Japan. '''Pale skin, petechiation and necrotic abscesses within the muscle of fish (that have a putrid odour when incised) are characteristic of ES'''. Mortality rates can depend on the amount of stress that the fish are kept under and high temperature, poor water quality and high organic fertility probably contribute to the onset and severity of the disease.

Unlike ''E. ictaluri'', '''''E. tarda'' is zoonotic''' and can infect humans. [[Edwardsiella ictaluri|'''''E.ictaluri''''']] causes '''''enteric septicaemia of catfish (ESC)''''' and '''only infects fish species''', whereas '''''Edwardsiella hoshinae'' infects birds and reptiles'''.
