Reply to comment by peer-reviewed-myopia in How our microbiome is shaped by family, friends, and even neighbors. Study of the gut and mouth microbiomes of thousands of people from around the world raises the possibility that diseases linked to microbiome dysfunction, including cancer, diabetes, and obesity, could be partly transmissible. by MistWeaver80

You believe wrong.

>It appears that any contact between the unborn fetus and the mothers’ vaginal microbiome (for example, through rupture of membranes in labor) results in early microbial seeding and potential long-term health benefits for the newborn. In a study of 18 maternal/newborn dyads, the microbiome of mothers and babies in three groups were compared: newborns born vaginally, newborns born via cesarean with standard post-op treatment, and newborns born via cesarean who were exposed to maternal vaginal fluids immediately following birth Dominguez-Bello et al., 2016. Within two minutes of birth, newborns in the last group had their mouth, face, and body swabbed with a gauze pad that had been incubated for an hour in their mothers’ vagina. These gut, oral, and skin microbiome of these newborns were more similar to vaginally-born newborns than to other newborns who experienced the standard cesarean birth. This similarity persisted through one month of life, when the study ended. These findings are consistent with population-based studies showing that children born via elective cesarean birth (no labor) are at higher risk for health problems like asthma compared to children who had some exposure to their mother’s vaginal microbiome during labor, even if labor ended in cesarean Kristensen & Henriksen, 2016.

Every baby that isn’t born via c-section goes through the vaginal canal, not every birthing mother poops or has a baby that comes into contact with her poop.

There is constant transfer of bacteria from gut to vagina. These systems are completely linked.

The person I was responding to brought up poop as a joke. Poop indirectly plays a role in all vaginal births.

““Every generation of mothers hands over its microbiome to the next, as the baby is coated with beneficial germs while being squeezed through the birth canal – but this doesn’t happen for babies born through C-section,” said co-author Martin Blaser, director of the Center for Advanced Biotechnology and Medicine at Rutgers.” Link. It’s not a poop/poop residue adjacent crotch that provides the bacteria, it’s the vaginal bacteria. There’s a reason they tell women to wipe from front to back.

Are you claiming that there is no gut bacteria in the vagina?

No, I’m not claiming that. There is gut bacteria in poop. There is gut bacteria in the vagina. That does not mean they are interchangeable. The exposure received in the vaginal canal is what’s beneficial for the baby.
