Gram-negative pleomorphic rods. Non-motile.
Colonies are gray, odorless, and nonhemolytic. Capnophilic, and optimal growth
conditions are on chocolate agar in a 5% CO2 atmosphere, on which after 24 to 48 h
incubation it forms typical colonies of 0.5-2 mm in diameter which can be moved
around on the plate like a semolina particle without losing their shape. No growth on
MacConkey agar. X and V factors are not required.

Isolated from tracheal-bronchial washes of horses.
Isolated from horses with chronic cough and in a few cases with pneumonia and/or nasal discharge.
