Gram-negative, 0.2-0.3 / 0.5-2.0 µm, pleomorphic rods, noncapsulated.
Colonies on chocolate agar are smooth,  convex, translucent, 1.0-2.0 mm. in diameter
in 24 hours, with a small granular area on top. Hemolysis is negative. Aerobic,
facultatively anaerobic, require X-factor but not V-factor for growth. CO
2 is not required.
Growth on MacConkey agar is negative.
Isolated from the preputial sac and vagina of dogs.
May belong to normal flora of the preputial sac and vagina of dogs. Probably low pathogenicity for dogs.
