The breastmilk received from the mother is one of the factors determining how the bacterial flora will develop in the newborn baby.
However, the composition and the biological role of these bacteria in infants remain unknown.
The most common bacteria in colostrum samples were Weissella,
Leuconostoc, Staphylococcus, Streptococcus and Lactococcus.
The study found however that they were not yet able to determine if these bacteria colonise the baby's mouth or whether oral bacteria of the breastfed baby enter the breastmilk and thereby changing its composition.
The study also revealed that the milk of overweight mothers or those who put on more weight than recommended during pregnancy contains a lesser diversity of species.
Breast Milk Contains More Than 700 Species of Bacteria
