Babies born vaginally have more friendly bacteria than those born by C-Section.
A recent article published in Scientific Reports reported that gut micro-flora of infants born vaginally without exposure to antibiotics or C-section contained significantly more friendly bacteria than infants born vaginally and or by C-section.
Early life friendly bacteria in the gut is critically important to the healthy development of a baby and throughout its life. In the first hours and days following birth there is a rapid evolution of friendly gut bacteria, particularly strains of Bifidobacterium, which is the dominate infant gut colonizer over the first 12 weeks of life.
When initial exposure to the mother’s gut flora is altered by Caesarean section (C-section) and prophylaxis antibiotics to prevent infection during C-section, the infant’s gut flora has also been shown to significantly differ from babies born vaginally with no exposure to antibiotics.
Intrapartum antibiotics for GBS prophylaxis alter colonization patterns in the early infant gut microbiome of low risk infants
