Gram-negative, pleomorphic rods. Non-motile.
Colonies are 1.0-1.5 mm in diameter, regular, slightly raised, circular, with an entire
margin surrounded by a zone of beta-haemolysis, after 24 h aerobic incubation at 37
ºC. No requirement of X- or V-factor. Pigment is not produced.

Isolated from diseased tortoises and turtles.
Undetermined.
