Peptostreptococcales is an order of Gram-positive, endospore-forming, and predominantly strictly anaerobic bacteria within the class Clostridia. [1]
The order Peptostreptococcales encompasses three validly published families: [1]
These families contain diverse anaerobic species widely distributed in animal-associated and environmental microbiomes.
Peptostreptococcales members are anaerobic fermenters of carbohydrates and amino acids, often producing short-chain fatty acids such as acetate, butyrate, and propionate. Spore formation enables survival in challenging environments and facilitates transmission.
Several species within the order are medically significant, notably Clostridioides difficile , an important human pathogen responsible for severe gastrointestinal infections associated with antibiotic usage.
