Non-sporeforming
Anaerobes
NOTE: Figure legend in text
indicates that each of these
organisms is a bacillus (i.e., rod-
shaped). This is INCORRECT.
Peptostreptococcus is, as the
name indicates, a coccus.

Colonies of Actinomyces
NOTE: Molar tooth appearance
of colonies on agar can help
remind us that the oral cavity is a
common niche for Actinomyces.

NOTE: Sinus tract originating in oral cavity has
made it’s way to the surface at the jawline.
