  1. A 40yr old man visiting a coastal area had sea food for dinner consisting of oyster and shrimps. Next morning he developed severe abdominal pain, diarrhea, vomiting and fever.
    The stools were blood stained. The man did not require any rehydration therapy and was treated with ciprofloxacillin and recovered in about 2 days.
    These clinical features are typical of infection by

    a) Vibrio cholerae

    b) Vibrio parahaemolyticus

    c) Vibrio vulnificus

    d) Salmonella typhi

    e) Rota virus

    The answer should be Vibrio parahaemolyticus.
    When ingested, V. parahaemolyticus causes watery diarrhea often with abdominal cramping, nausea, vomiting, fever and chills. Usually these symptoms occur within 24 hours of ingestion. Illness is usually self-limited and lasts 3 days. Severe disease is rare and occurs more commonly in persons with weakened immune systems. V. parahaemolyticus can also cause an infection of the skin when an open wound is exposed to warm seawater.
    Most people become infected by eating raw or undercooked shellfish, particularly oysters. Less commonly, this organism can cause an infection in the skin when an open wound is exposed to warm seawater.
