I would think 40% of mothers would still be giving pathogenic bacteria, one way or another, via normal birth.
I would think that this might be a good place to use a lab cultured product where you can practice some screening control.
“C-section babies are not exposed to maternal fecal microbes”
OK, so how are babies delivered vaginally exposed to fecal microbes?

The above study says the vaginal biome doesn’t affect the baby’s gut, so vaginal birth vs c-section wouldn’t matter anyway...
Ah science. Contradictory results.
Yes, that would seem logical. The article didn't give a reason that pathogens would be higher for C-section babies but if babies get what they need from a vaginal birth a very tiny amount must be sufficient.
What role does breastfeeding play in all that?
Does that help impart beneficial bacteria to the baby?
FWIW, I have been doing a lot of research into probiotics and some of the most benefical ones and came up with these interesting sources.

Just FYI.
Exposure breeds immunity.
the way to solve this problem is to get fecal transplants from great athletes.
