      Clinical significance
      V. parahaemolyticus are the leading course of foodborne intestinal infections, almost always associated with the consumption of oysters, raw fish or shellfish.

      They are primarily associated with diarrhea, but it had occasionally isolated from extraintestinal sites. They causes gastroenteritis with nausea, vomiting, abdominal cramps, lowgrade fever and chills.

      The diarrhea is usually watery, but can on rare occasions be bloody.

      Rehydration is usually the only treatment needed, but in some severe cases the patient requires hospital admission. Antimicrobial therapy may be beneficial.

      Facultative anaerobic

      Colonies may produce a brown pigment.

      It is common for pure cultures of vibrios to produce multiple colony morphologies (as many as 5), best seen on blood agar.

      Variations in morphology include smooth, rough, convex, flat spreading, and compact in various combinations.
