Do we get gut bacteria from the people around us? Where does a newborn get their gut bacteria from?

- ninetyninenine 1y agoThe entry point to the gut is from the mouth so because of that, I think food is where most of the gut bacteria comes from.
- cwmoore 1y agoSure, as long as you hold your mouth and nose closed when not eating.
- asdff 1y agoYou have a back door as well for the gut that tends to open at least once a day. We know fecal matter is in the air in most bathrooms. It wouldn't surprise me if you got an infusion of community fecal biome right into your anus every time you used a restroom that isn't your own.
- ninetyninenine 1y agoYes but usually when the back door opens things are exiting the gut rather then going in. So I don’t think that counts. There are cases where things do enter the back door but I think that’s just humans getting creative and it wasn’t designed for entry.
- asdff 1y agoIts not like there is positive air flow keeping any microbes in the air out and away. If something lands on there it can probably colonize then spread to the inside slipping through the sphincter.

- evanjrowley 1y agoIt's not just food as many commenters are pointing out. It could be from what people are drinking, even water, if oral delivery is not sanitized.
- cwmoore 1y agoSo if the choice is between unsanitary water or sterile and containing chlorine, etc., which has the effect of strengthening the microbiota so that the resulting population increases perceived wellness in the host organism’s sociopolitical fitness, its simple enough, we all stop eating and drinking for ultimate safety and maximum paperclips.
- evanjrowley 1y agoChlorine is not the only way to sterilize water. Ultraviolet sterilization is a chemical-free option suitable for many use cases: https://en.m.wikipedia.org/wiki/Ultraviolet_germicidal_irradiation https://en.m.wikipedia.org/wiki/Ultraviolet_germicidal_irrad...
- amanaplanacanal 1y agoNewborns get a lot from their mother. They have very little stomach acid, so whatever they are getting goes straight through to their gut.
