Gram-negative, motile rods, nonspore-forming, nonencapsulated, 0.7 x 2.5 µm.
Two colony types are produced. Colonies on TSA are 4–5 mm in diameter; one colony
type is opaque, circular and beige in colour, while the other is translucent, after 48 h at
30 ºC. Non-hemolytic on blood agar. No brown diffusible pigment is produced on TSA.
Growth is observed up to 45 ºC but not at 50 ºC after 48 hours or at 4 ºC after 7 days
on sheep-blood agar.Optimal growth occurs after 24 hours at 30 ºC. Grows on
MacConkey and in the absence of NaCl but not in 6% NaCl medium. Optimal growth
occurs at pH 9 after 24 hours on TSA, but not at pH 4.5.
Isolated from a wound culture from a patient  in Taiwan. Resistant to vibriostatic agent O/129, amoxicillin, amoxicillin + clavulanic acid,
ticarcillin, ticarcillin + clavulanic acid, cephalothin, cefoxitine and erythromycin.
Undetermined. Wound contaminant.
