I'm trying to think of an analogy. If the healthy vaginal flora has microbials ABC and we add XYZ which don't normally inhabit it, the XYZ could overgrowth the ABC. Not unlike gardening. If you have a garden and plant a strong ground cover, it will over take the garden, disrupting the existing vegetation. Of course, the vagina has a different ph than the gut. The gut is very acidic. Different "weeds" grow in different gardens. If the garden ph is acidic, different weeds grow than in alkaline environments.
So, if you put something that thrives as beneficial in one environment, it could take over another environment. Just like when we ferment vegetables, we add an acid, or salt to inhibit "bad" bacteria from growing, while allowing the "good" bacteria to thrive.
I'm mixing my metaphors. But, basically, the gut can manage to balance the introduction of the microbials from kefir, it has hundreds of competing microbials. The vagina has a different ph, different microbials, and a different microbial balance. And disrupting that with isolated strains, or "foreign" bacteria and yeasts doesn't sound natural, traditional, or preferable, from my understanding of the immune system.
Granted, many folks have disrupted gut microflora. I maintain the path to *correcting* that isn't through introduction of bacteria in non-traditional routes. Most probiotics sold do not even thrive due to the improper ph of the stomach and gut. Microbials need a specific environment in which to thrive. Increasing consumption of alkaline forming foods, and preparing foods to maximize nutritient absorption, and consuming whole food probiotics will improve the gut flora and the immune system.
I don't believe that we want to "inoculate" the baby's sterile gut with the "wrong" bacteria due to antibiotics, or probiotics,
creating imbalance of the normal vaginal flora.
Also, probioitc capsules have significantly fewer viable bacteria which actually reach the gut. Single strain probiotics in quantity could "overwhelm" the gut flora, just as candida can. Cultured dairy has the proper ph for specific microbials to thrive. But, even cultured dairy would have a limited number of microbials which are being introduced to the vagina directly.
Kefir and yogurt or bottled probiotics are just not a natural source of "healthy" microflora to introduce to baby through the vaginal canal, from my understanding. Not because they aren't beneficial to the baby's gut, but because they may kill off the NORMAL bacteria in the vagina which are meant to inoculate the gut.
