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 non-hemolytic 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.
