Plesiomonas shigelloides is a bacterium of the family Vibrionaceae.
Shigelloides is a mild self-limiting gastroenteritis caused by the consumption of food or water contaminated with the bacterium.
Plesiomonas shigelloides has been isolated from freshwater fish and shellfish, and a variety of animals including cattle, goats, swine, cats, dogs, monkeys, snakes, and toads. Most human P. shigelloides infections are suspected to be waterborne and associated with freshwater aquariums and fish tanks.
