Non-Sporeforming Anaerobes

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

Non-Sporeforming Anaerobes (cont. )

Most Common Sites of Anaerobic Infection

Characteristics of Anaerobic Infection

Characteristic Clinical Signs of Anaerobic Infection

Anaerobic Gram-Positive Non-Sporeforming Bacterial Infections

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

Diseases Associated with Anaerobic Gram-Positive Bacilli

Gram Stain and Macroscopic 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.

Actinomyces Infections

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

Colonized IUD Resulting in Pelvic Actinomycosis

Epidemiology of Actinomycosis

Sulfur Granule from Sinus Tract of Actinomycotic Infection

Epidemiology of Propionibacterium (doxycycline)
