What would probiotic gut bacteria look like? (Bifidobacteria, lactobacillus, etc) What would their home in the gut be like?
I’m still doing researches right now! I didn’t really think about missions taking place around the digestive system YET because I wouldn’t risk people to feel sick imagining that-
what do you mean a vaginal birth kickstarts the baby’s immune system⁉️
HI! YOURE PROBABLY GONNA GET A NOTIF FOR THIS ASK AND FORGET THAT YOU SENT IT LIKE OVER A WEEK AGO! SO HI! IM HERE FINALLY! LETS TALK ABOUT. VAGINAL BIRTH AHUAHSHEHAHHA YAY
gonna put it under the cut cause it came out long and i don’t want to clog anyone’s feed with unwarranted autistic bacteria monologues:
okay. so when a baby is delivered vaginally, it gets coated in all the bacteria species that call the vagina their home (mostly a bunch of Lactobacillus species, (which produce lactic acid, maintaining the vagina’s acidic pH)).
anyway. since newborns haven’t mounted a great immune system yet, being coated in the vaginal flora bacteria right off the bat gives it its first exposure, helps kinda start off their skin microbiome then and there!
contrarily, c section babies obviously don’t pass through the vaginal canal, so they don’t get bathed in that yummy new bacteria goodness. that’s not detrimental, ofc. they’ll quickly be exposed to other bacteria postnatally soon after and eventually mount their immune response and gain their skin microbiome.
i can’t say off the top of my head if there’s like, a significant or even quantifiable immune difference, or if it’s more of a general theory. but. yeah! that’s how vaginal birth babies tend to have “kickstarted” immune systems in comparison to c section babies!! very glad you asked. i will jump at any chance to talk about bacteria. ahahheheheheheheh
Still unpacking from my move from Reddit, have some germs
Unfiltered yammering under the cut
So I know that lactobacillus/lactic acid guys is what those squishmallow looking things were in canon, but I wanted to see what they’d be like if they filled more of a sophont niche, so I just started from scratch completely, plus the elsewhere fic I’m writing has a lactobacillus as the MC. I don’t know where most of these ideas came from, but one of the things I didn’t include in the ref was that their claws can extend and reveal tiny lactase channels, for instance the green one does that for a living where they stab their claws into the lactose and it melts it. I should design more germs idk who to do. Maybe streptococcus
Psychological state is known to influence immunity by its impact on our essential microbiome – the vast community of microorganisms that share our body – but the details of how are unclear. This study in mice identifies nervous pathways that interact with intestinal glands that produce mucus which in turn influences the vigour of beneficial bacteria (the study looks at Lactobacillus)
