Edwardsiella tarda is the etiologic agent of acute to chronic edwardsiellosis in fish and other species (1). It is a Gram-negative facultative anaerobe that is motile by peritrichous flagella. Edwardsiellosis is an important fish disease that negatively impacts aquaculture industries throughout the world (2). Moreover, E. tarda can cause disease in humans, where it is typically associated with gastrointestinal infections that may progress to hemorrhagic septicemia (3). Historically, E. tarda causes a sporadic disease in channel catfish (Ictalurus punctatus) called emphysematous putrefactive disease, which may begin as small punctate cutaneous erosions that progress to abscesses deep within the musculature (1). However, E. tarda is being increasingly isolated from large outbreaks of gastrointestinal septicemia in commercial channel catfish operations. E. tarda isolate C07-087 is from an outbreak of gastrointestinal septicemia in a commercial catfish pond in Mississippi.
