https://journals.sagepub.com/doi/10.1177/17562848261452497 A group from Denmark. Ridiculous donor criteria. The fact that they passed 13 of them highlights that. It should be no surprise that they made patients worse. Yet they didn't even try.

https://journals.asm.org/doi/10.1128/mbio.00711-26 I wonder why they had collected the infant's stool prior to symptom onset.

This is absolute nonsense. Microbes are generally "species native", which means that pigs have their own strains of certain bacteria, mice have their own strains, and humans have their own strains, etc. There are FMT consensus guidelines linked on the website that conclude that "universal...

Firstly, that's a nonsensical sentence. Secondly, it's not true. There are plenty of sources of FMT, including most clinical trials, that do not use "many different donors". Third, there are many different reasons for "fecal donations", with widely varying criteria for donors. For example, C...

I'm not a fan of TikTok, but everything on TikTok is sketchy? That seems like a stretch. And why are you on TikTok if everything on TikTok is sketchy? And you go from TikTok to Reddit? You seem to spend a lot of time on sketchy websites. The questionnaire absolutely asks about family disease...

This is a really weird claim. It's literally the main heading of the front page: "Working to find the fewer than 0.1% of people with healthy, unperturbed, disease-resistant microbiomes" And on the Donors page, "0.1%" is in bolded text multiple times. It's quite odd (and deceptive) that they're...

This one is quoting multiple redditors. It appears that this person didn't bother to review the website at all. The first blog post is about "our 1 in 23,000 donor". Not quite as rare as the "one in hundreds of millions" for the lottery. The "video of jogging for 240 minutes" part is probably...

Addressing some of the specific claims being made: This is a Google Maps bug. If you remove the suite number from the address, it shows the correct location. This is laughable. Zip-lock bags are food-safe. One of their primary uses is to store food in, and then eat that food. Poop is not...

There are two reddit threads that show up in search results that are full of misinformation. Since reddit is a "free-for-all" where anyone can anonymously write anything they want, there is nothing that can be done about it other than to create threads about them and hope they show up during...

It's important to note that even if you can get FMT from these sources, that doesn't mean it's safe to do so. Virtually every source of FMT is only screening & using whoever is easy to locally obtain. High-quality (safe & effective) stool donors are very rare, and these places are not putting...

I recall an earlier study that Martin Blaser was either involved in, or commented on, which found that anti-parasitic medications caused minimal changes to the gut microbiome. I can't find it now though. I tried a web search for "anti parasitic medication microbiome change minimal blaser". The...
