Analysis of Clostridium cluster XI bacteria in human feces

Six species and one group of Clostridium cluster XI, Clostridium sordellii, Clostridium bifermentans, Clostridium difficile, Clostridium hiranonis, Intestinibacter bartlettii, and Romboutsia lituseburensis and the Terrisporobacter glycolicus group, respectively, in human feces collected from 18 healthy adults were analyzed with real-time PCR. Although individual differences were recognized, the predominant colonization of C. sordellii and I. bartlettii in the human large intestine was identified.
