Yes, that was my thinking. I found one table, in this guide by a testing company https://www.diagnosticsolutionslab.com/sites/default/files/u16/GI-MAP-Interpretive-Guide.pdf page 19. It lists some commensal/normal bacteria. But, searching for some of these, for example, if you look at Bacteroides fragilis, in this table listed as a commensal bacteria with important role, it is also associated with disease, depending on the context https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2176045/ So I guess its up to the bacteria been in the right level... overgrowth /dysbiosis would make any bacteria problematic... although I dont know if this is backed by research

yeah... but these are not always peer reviewed sources. Like with the gut bacteria list, it was sources from this "textbook" http://www.textbookofbacteriology.net/normalflora_3.html but the textbook it self doesnt provide clear references to the sources. If you look, Bacteroides fragilis, one of the species listed, this species is rather a pathobiont, rather than a benefical bacteria. Anyway, subtle difference, but I was hoping to hear from anyone who knew of a study showing a list of strictly beneficial, comensal, bacteria. Anyway, I just wanted to see what species people came up with...

yes... but its Wikipedia...which I love, but Im after peer reviewed sources...

Thanks for your comment, dimreepr... it led me to this article Colonization of the human gut by bovine bacteria present in Parmesan cheese https://www.nature.com/articles/s41467-019-09303-w didnt know about that! That's true, that's one good example, but a bit broad, need to check if we know what species are actually responsible.... Looking for any other good examples like this... Thanks, Sensei

Hi, Can anyone mention some key *human* gut (large intestine) bacterial species that are considered beneficial, confirmed by peer-reviewed research? There is a lot of literature establishing links between diseases and higher or lower diversity or with particular species of gut bacteria, plus there is a lot of variation from person to person in terms of microbial composition. But, is there a consensus on some gut bacterial species that are beneficial to the body, and commonly found in anyone? Thanks! Freddy
