Gram‐negative, fermentative, nonmotile, coccoid or rod‐shaped bacterium of the family Pasteurellaceae, part of the normal mammalian microflora. This bacterium has been associated with periodontal infections and, in particular, early‐onset, aggressive forms of periodontal disease.
Genus within the family of Brucellaceae. Gram-negative non-motile aerobic rods associated mainly with animal disease. Carbohydrate fermenters, no gas production. Micro-aerophilic conditions may aid primary isolation.
A genus of Gram-negative nonmotile aerobic bacteria that are characteristically spherical or rodlike in shape but occasionally grow into branching filaments. Actinobacilli cause disease in animals. The species A. mallei causes ‘glanders, an infection of horses that can be transmitted to man.
A genus of gram-negative coccobacilli that are parasites of hoofed mammals, and, rarely, of humans.
