The researchers looked into the different types of bacteria that was found in 4 month old infants. They also looked at whether or not these infants were born via caesarian vs vaginal delivery, and whether they were formula-fed or breast-fed.
This is an interesting study because there has always been great "lively discussions" over whether women should be having elective caesarian deliveries and the many benefits of breastfeeding in the Naturopathic community. Of course, I must note that emergency caesarian deliveries are necessary and can be life-saving.
Naturopaths are also very interesting in the gut microflora because it is such an important factor in both our digestive and immune systems -- these are key systems to our overall health!
Interestingly, they found that infants born by caesarian delivery did not have as much Escherichia-Shigella and Bacteroides species in their gut bacteria versus infants who were delivered vaginally. In addition, infants who were born by elective caesarian delivery had particularly low gut bacteria amounts and variety.
They also found that formula-fed infants had more Clostridium difficile in their gut bacteria versus breast fed infants.
