Bacteria at Birth

When we’re born, we’re born microbiotically sterile.  During birth, the baby becomes “infected” with normal flora.  During a normal vaginal birth, lactobacillus, particularly lactobacillus acidophilus, dominates the vaginal canal and as a result is the first flora to populate the newborn.  In a cesarian section, the baby doesn’t acquire the same microflora.  Instead of the normal vaginal flora the baby acquires the flora dominating the hospital setting, including staph and enterococci.  These infants have a significantly higher risk of developing childhood allergies.  The following two days of life, other organisms including rectal flora like E. coli, streptococcus, and klebsiella populate the baby.

Breastfeed vs. Formula

Following the first two days, microflora depends on breast feeding versus formula feeding.  In breastfed babies there is a rapid increase in the bifidobacter bacteria, making up approximately 95% of fecal flora during this time.  Breast milk contains oligosaccharides that stimulate the growth of bifidobacteria in the lower GI tract an lactobacilli in the upper GI tract.  If the baby is formula fed, only 22% of fecal flora is bifodobacter and the other 70% of bacteria observed in the fecal flora are enterobacteria, flora that are considered to be much less desirable.

Why give probiotics to a baby?

The immune system of the newborn baby is immature and biased toward forming an allergic reaction (this includes eczema, hay fever, allergic rhinitis, and asthma).  The internal bacterial flora train the immune system away from developing an allergic response.  If the baby doesn’t get access to sufficient flora, the re-balancing of the immune system doesn’t take place.  There is almost undeniable evidence and potential benefit by the use of probiotics for a period of 6 months on a daily basis.  Probiotics have the potential to lower the risk of the baby developing allergies.  Even though breastfed babies have higher numbers of bifidobacteria, the actual total numbers of bifidobacteria are lower than they were decades ago, so even breastfed babies can benefit from supplementation.  Using probiotics in newborns can prevent allergies from developing in 25% of cases by supporting the immune system.  We all experience the same environmental antigens, but it is the functioning of our immune systems that determine who develops allergies and who does not.

Get Started

Talk with your naturopathic physician about developing a protocol that is right for you and your baby to prevent allergies from forming in the first place.  Prevention is always easier than cure.  If you are an adult with allergies, I advise asking your physician about starting an individualized probiotic protocol to strengthen your immune system.  Keep in mind, it can take 1-3 months to see benefit, so hang in there and stick with the plan.  Not all probiotics are created equal, in fact some over the counter formulas may contain no actual live bacteria at all.  Make sure you use a company recommended by your health care practitioner to ensure you are taking a quality, third party tested product.
