Species incertae sedis; strains are different from true members of the genus by their aerogenic capacity and their negative catalase
reaction
Coccobacillary, Gram-negative cells.
Colonies are nonhemolytic and V-factor independent.
Growth on MacConkey is negative.
Isolates are obtained from respiratory and genital tract infections in horses and also from humans who have had contact with horses.
Respiratory and genital tract infections in horses and also infections in humans who have had contact with horses. A wound infection
after horse bite has been reported.
