The Peptostreptococcaceae are a family of Gram-positive anaerobic bacteria in the class Clostridia. A majority of members are identified as obligate anaerobes. Peptostreptococcaceae metabolize via fermentation and are important in the digestion process of many ruminants. Shape of the bacteria varies from cocci, rods or filaments, among species. Most strains fall within the size of 0.6-0.9 μm. [2]
Taxonomy
Origin of nomenclature is derived from the Greek "peptos", meaning digested, and Streptococcus, a bacterial genus name combine to form Peptostreptococcus--the "digesting streptococcus". [2]
Gut Microbiota
Several members of the Peptostreptococcaceae are well known inhabitants of the digestive tract. Microbiome studies of animal feces have corroborated this. Notably, an unclassified group of Peptostreptococcaceae has been reported making up a significant portion of the microbial community in domestic cats,[3] while other studies have not found a significant presence of Peptostreptococcaceae.[3] Peptostreptococcaceae have been found to be enriched in the gut microbiota of blood drinking species such as vampire bats and the vampire ground finch.[4]
Pathogenesis
Humans
Clostridioides difficile is a notable human pathogen in this family. Peptostreptococcaceae have been of interest for several other bowel diseases as biological marker or causative agent. Decreased abundance has been reported for Crohn's disease,[5] while the genus Peptostreptococcus appears to be more common in patients diagnosed with colorectal cancer.[6]
