V. mimicus has been associated with many sporadic casesof diarrheal disease on the gulf coast of the United States.
V. mimicus is so named because it resembles V. cholerae in itsbiochemical reactions. V. mimicus, unlike V. cholerae, does not ferment sucrose, but like V. cholerae it grows well at a 0.5–1% concentrated sodium chloride. Infection is acquired by eating seafood, especially oysters. The organisms cause a gastrointes-tinal disease, which is usually self-limited.
