Historical synonyms:
Vibrio fluvialis biogroup II.
Gram-negative, straight or curved  rods, motile. Sometimes may produce lateral
flagella on solid media. Not swarming on complex media.
Produce yellow colonies on TCBS agar (ferment sucrose).
Can grow in nutrient broth with: 1% NaCl, 6% NaCl, 8% NaCl & 10% NaCl. No growth
in 0% or 12% NaCl.
Grow
s at  30-40 ºC. No growth at 4 ºC.
Isolated from natural waters (estuaries) and animals that lives there; occasional from human and animal feces (pig and rabbit feces).
The role of V. furnissii as the actual cause of the diarrhea was only speculative.
