Nine mildly pleomorphic Propionibacterium rods appear in six groups: three singles and three touching pairs in shallow V, angled, and end-to-end arrangements.
Current-genus representative reconstruction Editorially reviewed

Current-circumscription, type-species-anchored Propionibacterium reconstruction with nine pleomorphic rods in three single and three paired groupings. Former cutaneous species now placed outside the genus are excluded; this plate is representative, non-universal, non-diagnostic, and not a micrograph.

Propionibacterium (largely reclassified as Cutibacterium for skin species) is a genus of Gram-positive, anaerobic to aerotolerant bacteria that produce propionic acid as their primary fermentation product. P. acnes (now Cutibacterium acnes) is the dominant skin commensal and acne pathogen, but the genus appears across multiple cancer microbiome studies.
