Gut Bacteria and Immunity
Bacterial flora in the gut plays a role in the production of cross-reactive antibodies, which the immune system produces to fight against normal flora. However, these antibodies also prevent invasion and infection by other pathogens, as they can effectively fight them.
Bacteroides are the most prevalent bacteria in the gut. They are believed to play a role in the onset of colitis and colon cancer.2Rinninella, Emanuele, et al. ‘What Is the Healthy Gut Microbiota Composition? A Changing Ecosystem across Age, Environment, Diet, and Diseases.’ Microorganisms, MDPI, 10 Jan. 2019, www.ncbi.nlm.nih.gov/pmc/articles/PMC6351938 Another abundant gut bacteria is bifidobacteria, which are often recognized as friendly bacteria.
