Gram-positive, typical, pleomorphic coryneform rods, arranged in palisades or
V-shaped forms. Nonmotile. Nonsporing.
Colonies are cream, slightly rough, nonhemolytic, 2.0 mm in diameter after 48 h of
incubation at 37 ºC on sheep blood agar. Grows well under anaerobic conditions;
CAMP reaction is negative.
Isolated from the human throat.
Strains isolated from patients suffering from tonsillitis has unclear clinical significance.
Gene coding for diphtheria toxin is absent.
