Targowski and Targowski 1984.
Gram negative coccobacilli, rods , filamentous forms, non-capsulated.
Colonies on chocolate agar are smooth, high convex, opaque, grayish. Hemolysis is
negative.
Aerobic, facultatively anaerobic, require V-factor but not X-factor for growth. CO2
enriched atmosphere favorize growth. Growth on Mac Conkey agar is negative.
Isolated from the gastrointestinal tract of rabbits with mucoid enteritis.
Not established.
