    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...

    Blog Fuck Portion Control by Nathan Guy Hatch

    I only had to read this much to figure out that this person is a loon. Electrons are constrained in the ETC by 1) the proper folding of its proteins, which fully surround the electron carriers except in places where electrons are designed to get in or out, and 2) the membrane lipids, which are...

    Origins Vaginal bacteria on newborn skin produce a lipid that reaches the brain and affects neural signaling (Apr 2026) Vaginal microbiota transfer ameliorates cesarean-associated neurodevelopmental deficits in mice via N-bc2S1P synthesis on neonatal skin

    I very much agree with the point overall, but this isn't strictly true. C-section is a surgery and so it has risks that don't occur with non-surgical birth. One would need to look at the likelihood of complications of vaginal birth in various environments with different levels of infection...

    Sources Does anyone have any experience with Microbiota Therapeutics at UMN (University of Minnesota)?

    Likely because they're only interested if you're either a hospital or a researcher coming to them with a clinical trial proposal. It likely has nothing to do with them being a good or bad source (though the failure for C. diff implies they're not a very good one at all) but rather that they have...

    FMT Towards a Standard Protocol for Fecal Microbiota Transplantation in Irritable Bowel Syndrome [meta-analysis/summary, Apr 2026]

    This was recently published. It's not a new study, rather it summarizes the current state of knowledge and experience. In a number of cases it addresses things that Michael, myself, or others posting online have noticed but that I haven't noticed being mentioned before...

    Procedure Looking for advice on autologous FMT

    It's mostly eliminated through the urine so it shouldn't have. The only thing about beta-lactams like amoxicillin that works against you is that they're bactericidal, i.e. they actually kill bacteria rather than just stop them from growing. Thus if you did get amoxicillin into a bodily fluid...

    Procedure Looking for advice on autologous FMT

    Makes perfect sense, this is one of those times when the cost of NOT taking abx is worse than the potential damage to the microbiome. You wouldn't have wanted to wait until you had a life-threatening infection to start taking them. I hope for you that this is the case. It's not impossible that...
