''Peptoniphilus'' is a genus of bacteria in the phylum

Bacillota The Bacillota (synonym Firmicutes) are a phylum of bacteria, most of which have Gram-positive cell wall structure. They have round cells, called cocci (singular coccus), or rod-like forms (bacillus). A few Bacillota, such as '' Megasphaera'', ...

. They are non-saccharolytic, use peptone as a major energy source and produce butyrate.

Clinical relevance

This genus is part of the vaginal and gut microbiota. They have been reported to as present in diabetic skin and soft tissue infections, bone and joint infections, surgical site infections, chorioamnionitis and bloodstream infections. They are typically found as part of polymicrobial infections but are difficult to recover with usual clinical cultures. They have been increasingly reported with the more widespread use of 16S PCR and

for identification. They are noted to be linked with an impairment of wound-healing in patients with diabetic foot ulcers if present in abundance during the initial infection.
