Examples of Pathogenic Microbiota of the Large Intestine. The pathogenic oral bacteria in the large intestine may have negative ramifications in respect to gut health and motility disorders. Some of the more common pathogenic microbiota of the large intestine may promote motility disorders, such as Crohn’s disease and gastroenteritis. Information was adapted from the NIH Microbiome Database (Published 2008).
