If you suspect this organism, make SURE you let the lab know this information. In non-coastal areas, a TCBS agar, which will help isolate Vibrio, is not routinely set up on stool culture. I'm not sure whether labs in coastal areas routinely use this plate, so it is best to call the micro lab and ask ahead of time.
TCBS agar is high in bile salts, and helps to screen out normal flora organisms that might mask just a few colonies of this organism.
Remember, enteric pathogens sometimes are present in low numbers in feces. There are overwhelming amounts of enteric bacteria of many types, so anything that can select for what you're looking for will help.
Usually a notation such as "Rule out Vibrio" will help the micro lab know what you're looking for. Make sure you make this notation prominent however. It's always best to call ahead so that they will know something like this is coming in. If we receive calls like this we make a note and put it right on the incoming culture station bench and will periodically check to see if the specimen has been received.
Don't take things for granted. If you're looking for any type of special organism, always check with microbiology. Labs can add extra plates if you're looking for something specific, or make a notation on the culture so that the tech reading the plates will know what you're suspecting.

Thx bacitech, but is it Vibrio vulnificus or Vibrio hemolyticus? {Im having trouble finding this answer.} By the way thanks for the dialogue because recently the forum has been a little dead.

I don't know that much about these two bugs as we just don't see them, so I looked them up on the CDC website (which is a GREAT website, BTW, with LOTS of information).
V. vulnificus looks like it is the more pathogenic of the two, but also isolated less often. Curiously, sushi isn't mentioned as a source of infection.
I DO know that sushi has been implicated in parasitic infections with D. latum, which is the fish tapeworm.

You won't ever catch me eating raw fish. These worms can end up to be about 25 feet long! It pays to know where your sushi fish comes from.
"Diphyllobothriasis occurs in areas where lakes and rivers coexist with human consumption of raw or undercooked freshwater fish. Such areas are found in the Northern Hemisphere (Europe, newly independent states of the former Soviet Union (NIS), North America, Asia), and in Uganda and Chile."
Obviously the US is not immune.

Here's another URL regarding tapeworms, including fish tapeworms. They specifically mention sushi.
