A genus of gram-negative, facultatively anaerobic bacteria (family Enterobacteriaceae) containing motile, peritrichous, nonencapsulated rods. The type species is Edwardsiella tarda, which is occasionally isolated from the stools of both healthy humans and those with diarrhea, from the blood of humans and other animals, and from human urine. Edwardsiella tarda is an etiologic agent of gastroenteritis in humans. The two other species in this genus are Edwardsiella hoshinae and Edwardsiella ictaluri.
