Breast Milk Contains More Than 700 Species of Bacteria - Spanish researchers have traced the bacterial microbiota map in breast milk. The study has revealed a larger microbial diversity than originally thought (more than 700 species) and that it changes over the period of lactation, with the weight of the mother & by delivery method of the baby (c-section vs. vaginal).
To create this microbiome (the identification of the set of bacteria contained within breast milk) scientists used a technique based on massive DNA sequencing. Thanks to their study, additional pre- and postnatal variables influencing the micriobial richness of milk can now be determined. Read more:http://bit.ly/WqB6oh
