Gram-negative, slightly curved rods, 0.3-0.5 x 3-4 μm. Motile by means of a single,
unsheathed, polar flagellum.
Colonies are pinpoint to 1 mm in diameter, nonpigmented, smooth, and translucent
after 3 days incubation on blood agar at 37 ºC. Alpha-hemolytic. Most strains grow at
42 ºC and on 1% bile media under microaerobic conditions. Most strains are
resistant to cephalothin (32 mg/l) and cefoperazone (64 mg/l) but not to nalidixic acid.
Isolated from the ceca of asymptomatic broiler chickens, the liver and intestinal contents of chickens suffering from vibrionic hepatitis,
and from human diarrhea.
Undetermined.

Positive results for catalase (most strains), nitrate  reduction and hydrogen sulfide.

Negative results for urease and indoxyl acetate hydrolysis.
