    Procedure SMT from China (selective microbiota transplantation)

    I'd be curious to see what the selected microbes are that they are transplanting in preference to others. Searching for the quoted phrase "selective microbiota transplantation" doesn't return many results, mostly just papers that mention the term but don't cite other research that explains more...

    Outcomes DNA stool analysis before and after FMT?

    Lactobacillus acidophilus is added intentionally to certain dairy products, it's not significantly present in the gut unless you're eating a lot of it. While there are other Lactobacillus species that are common (to be found at all) in the gut like L. gasseri, L. reuteri, and L. salivarius...

    Video The false promises of Bryan Johnson and Functional Medicine | The Bryan Johnson "Hit Piece". Surprising revelations in the New York Times put Johnson's integrity into question | Scott Carney

    Yes wow. The fact that someone with a GI disorder would be selling FMT made from his or her own stool seems very odd and I'd stay well away.

    Sources FMT for treating dysbiosis triggered by probiotics: Experiences? | CDD (Center for Digestive Diseases) and FMT safety discussion

    So I'm gathering that they only do the procedure via colonoscopy? Different medical centers do FMT procedures differently, some via enema, some colonoscopy, some gastroscopy. There used to be people using nasogastric tubes as well though that seems it might be less common now.

    FMT Case Report: Allergic reaction following fecal microbiota transplantation in children with autism spectrum disorder: a report of two cases (Jun 2026)

    That's interesting... both because donor avoidance of allergens didn't prevent the problem, and also because this was a classic anaphylactic reaction. Many of us on the autism spectrum have food sensitivities and/or allergies, but it was my understanding that classic allergic reactions like...

    Outcomes DNA stool analysis before and after FMT?

    That's probably true in terms of actionable information for the test taker personally. It's not like a test anyone takes right now will tell him or her whether FMT is promising or if so which donor to use. So basically if you take a test now, you're investing in the future of microbiome...

    Outcomes DNA stool analysis before and after FMT?

    How about you re-test after doing a FMT, since you're familiar with your pre-FMT results? As far as existing data, if you read almost any scientific paper about FMT they will show pre- and post-FMT microbiome data from the recipients, organized by phylum, genus, and sometimes species. They...

    Sources Looking for information or guidance about FMT clinics in Singapore

    It IS relevant, for two reasons. 1) It is actually quite often in science that there are unwritten procedural details that critically affect the success of a technique. I have often been told by the PIs (group leaders) in labs where I worked that a particular method that seemed useful to us had...

    Sources Looking for information or guidance about FMT clinics in Singapore

    No primary citations will reference preparation in a home lab, unfortunately. In the clinical science world, lab space is plentiful but regulations for human experimentation are strict--thus nobody would propose a study that doesn't have the material prepared by medical doctors or PhDs in a...

    Donors How can I go about finding a top tier donor in New York City ?

    The difference is he/she isn't selling anything! That's a huge difference--anyone can express the idea online that FMT is useful for anything. However if you sell a product, and make claims about it that aren't backed up by official sources, then you are asking for legal trouble. What about it...

    FMT Autologous fecal microbiota transplantation restores the infant gut microbiome and metabolome after antibiotics: a case report (May 2026)

    I'm guessing by "I wonder why" you mean "How did they have the foresight to". Otherwise the answer is rather obvious :-). Possibly this was a study planned in advance, and all participating infants' stool was collected at regular intervals in case any of the subjects were to require antibiotics...

    Causation Very interesting paper about metabolic roles in the gut microbiome (August 2024, human) A widespread hydrogenase supports fermentative growth of gut bacteria in healthy people

    Just wanted to report that this is no longer just a preprint! I don't know how I missed this, I was checking back periodically every few months for quite a while since I first saw this paper and it never had progressed past BioRxiv. Turns out it's been published since October of last year...

    Sources Is HumanMicrobes.org legit? Is it a scam? Are they really paying $500 for stool donation? Misinformation & fake reviews on reddit.

    I have to wonder why you are responding now on here to threads posted on Reddit three years ago. I can only speculate that you have gotten feedback from people through your activism in DC that these negatively toned threads are affecting their opinion of your intentions and/or willingness to get...

    Parasites An anti-parasitic medication (ivermectin) shifted Amazonian villagers’ microbiomes toward an urban profile (May 2026, n=335) Rapid microbiome restructuring associated with medical exposure in remote Amazonian Indigenous communities

    It seems to me that the authors of the first paper are not arguing that it is specifically the ivermectin that caused the changes, but rather "contact with the modern medical system". I agree this is a weird way to describe it (at least, I gather from how you present this that you also think...
