C-section or Vaginal birth, differences in bacteria
by Dr. Alan Kadish NMD
Not surprisingly nature provides our newborns with multiple distinct groups of bacteria, (microbiome) regardless of their haveing being born vaginally or via C-section, after 6 weeks. This study of 81 youngsters, at the Texas Children’s Hospital, documents that the contents of the mouth, skin, and gut are distinctly different and ….. it’s regardless of delivery method. This is significantly different than what is now consider an issue with a c-section delivery where people have adapted to the seeding method to their babies.
Working with multiple generations for over 30 years and now seeing the literature support, it’s not unusual to find that the parents are equally involved in the transfer of their bacteria and the environmental impact. Think of the bacteria as being similar to your bakery. They have known for decades that, as an example, sourdough is different when made in a different facility….it’s the bacteria found in the air that makes the unique characteristics of their products.
And to amplify the environmental aspect of our moving with our/your bacterial cloud, you might find this Science publication fascinating. What did they do ? The researchers took swabs of the interior of our homes and guess what…..they found that you bring your bacteria with you even when you move and it’s unique to the family. So are we a reflection of our environment or are you the maker of the environment ? Since this clearly affect your health we need to learn more about our environments.
There is another publication, in the Journal of Translational Immunology, that has shown that the microbiome of heavier people is different and can be potentially interpreted as “infectious” when you are in direct contact with these folks. Should that determine who you associate with or is this not an issue ? This mention is only to open the conversation and continue to evaluate the science and maximize your and your families health.
This is still a very evolving science as the real question that might make for a better outcome of your baby is should you be exposed to the hospital environment and the nasty bacteria commonly found there vs. you own home. Clearly, this is not a simple issue as each birth is unique. Perhaps bringing in your own linens and other products from you home, might be a way to bridge the bacterial gap ? Sounds like some additional personalization for your babies introduction to the world is in order.
I encourage you to weigh the evidence and consider the easy ways you and your baby can colonize with the “right” groups of bacteria and maximaze their health.

Human microbial communities are characterized by their taxonomic, metagenomic and metabolic diversity, which varies by distinct body sites and influences human physiology. However, when and how microbial communities within each body niche acquire unique taxonomical and functional signatures in early life remains underexplored. We thus sought to determine the taxonomic composition and potential metabolic function of the neonatal and early infant microbiota across multiple body sites and assess the effect of the mode of delivery and its potential confounders or modifiers. A cohort of pregnant women in their early third trimester (n = 81) were prospectively enrolled for longitudinal sampling through 6 weeks after delivery, and a second matched cross-sectional cohort (n = 81) was additionally recruited for sampling once at the time of delivery. Samples across multiple body sites, including stool, oral gingiva, nares, skin and vagina were collected for each maternal–infant dyad. Whole-genome shotgun sequencing and sequencing analysis of the gene encoding the 16S rRNA were performed to interrogate the composition and function of the neonatal and maternal microbiota. We found that the neonatal microbiota and its associated functional pathways were relatively homogeneous across all body sites at delivery, with the notable exception of the neonatal meconium. However, by 6 weeks after delivery, the infant microbiota structure and function had substantially expanded and diversified, with the body site serving as the primary determinant of the composition of the bacterial community and its functional capacity. Although minor variations in the neonatal (immediately at birth) microbiota community structure were associated with the cesarean mode of delivery in some body sites (oral gingiva, nares and skin; R2 = 0.038), this was not true for neonatal stool (meconium; Mann–Whitney P > 0.05), and there was no observable difference in community function regardless of delivery mode. For infants at 6 weeks of age, the microbiota structure and function had expanded and diversified with demonstrable body site specificity (P < 0.001, R2 = 0.189) but without discernable differences in community structure or function between infants delivered vaginally or by cesarean surgery (P = 0.057, R2 = 0.007). We conclude that within the first 6 weeks of life, the infant microbiota undergoes substantial reorganization, which is primarily driven by body site and not by mode of delivery.
The prevalence of obesity and diabetes mellitus type 2 is increasing rapidly around the globe. Recent insights have generated an entirely new perspective that the intestinal microbiota may play a significant role in the development of these metabolic disorders. Alterations in the intestinal microbiota composition promote systemic inflammation that is a hallmark of obesity and subsequent insulin resistance. Thus, it is important to understand the reciprocal relationship between intestinal microbiota composition and metabolic health in order to eventually prevent disease progression. In this respect, faecal transplantation studies have implicated that butyrate-producing intestinal bacteria are crucial in this process and be considered as key players in regulating diverse signalling cascades associated with human glucose and lipid metabolism.
