Hickman-Brenner et al. 1989.
Gram-negative, motile rods.
Grow in nutrient broth with 0 and 1% NaCl. No growth in 6% NaCl. No brown diffusible
pigment is produced on TSA. Beta-hemolysis on 5% sheep blod agar is variable.
Growth occurs at 36 ºC.  
Isolated from human clinical specimens (abscesses, wounds, skin, pleural fluid, and blood). No isolates from human stools were
reported. Resistant to vibriostatic agent O/129.
Undetermined. May be an opportunistic pathogen.
