Tests and diagnosis discussion for Vibrio vulnificus:

FDA Bad Bug Book (Excerpt)

Food Analysis: Methods used to isolate this organism from foods are similar to those used with diarrheic stools. To date, all food isolates of this organism have been pathogenic in animal models.

FDA has a genetic probe for V. vulnificus; its target is a cytotoxin gene which appears not to correlate with the organism's virulence. (Source: FDA Bad Bug Book)

Diagnosis of Human Illness:: The culturing of the organism from wounds, diarrheic stools, or blood is diagnostic of this illness. (Source: FDA Bad Bug Book)

Vibrio vulnificus (General): DBMD (Excerpt)

V. vulnificus infection is diagnosed by routine stool, wound, or blood cultures; the laboratory should be notified when this infection is suspected by the physician, since a special growth medium can be used to increase the diagnostic yield. Doctors should have a high suspicion for this organism when patients present with gastrointestinal illness, fever, or shock following the ingestion of raw seafood, especially oysters, or with a wound infection after exposure to seawater.
