Non-Sporeforming Anaerobes

Stains gram-variable or gram-negative, but not a gram-negative cell wall







Slide10 l.jpg

Gram-Positive Non-sporeforming Anaerobes Infections

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.



Slide12 l.jpg

Gram Stain and Macroscopic Colonies of Actinomyces Infections

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



Slide14 l.jpg

Cervicofacial Actinomycosis Infections

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