The breast milk newborns drink regulates their development of bacterial flora. The biological role of the bacteria found in the milk is still not quite understood, yet it is crucial.
DNA sequencing helped the Spanish researchers identify the group of bacteria in milk, known as microbiome. The microbial richness of breast milk is determined by a number of pre and postnatal factors.
The first type of milk a woman produces during pregnancy and in the early days of breastfeeding is called colostrum. This easy to digest milk is very nutritious and the perfect first food for a newborn. The scientists examined this type of milk and found that there are more than 700 different types of bacteria in it.
Analysis of colostrum samples revealed that the most common types of bacteria were Streptococcus, Lactococcus, Leuconostoc, Weissella and Staphylococcus. Samples of breast milk produced between the first and sixth month of pregnancy were also analyzed, the most common bacteria was Prevotella, Leptotrichia and Veillonella.
The ingestion of breast milk is the first time a baby has contact with microorganisms that will end up in it's digestive system. The researchers are currently trying to find out whether or not the role of the bacteria is either immune or metabolic.
