Breastmilk contains a complex community of bacteria, which can help in enhancing the gut microbiota of the infant. The determinants for the composition of milk microbiota are still not very well known.

 

A study with 393 mother-children pairs from the Canadian CHILD cohort showed that the milk microbiome at 3-4 months postpartum was dominated by Proteobacteria and Firmicutes and had discrete compositional patterns. The composition and diversity were associated with sex of the infant maternal BMI parity mode of delivery breastfeeding practices and other milk components.

 

The mode of breastfeeding proved to be one of the key determinants of milk microbiota composition. On the other hand, providing pumped breastmilk showed enrichment of potential pathogens and depletion of Bifidobacteria.

 

Overall, this study offered an insight into the composition and essential determinants of the human milk microbiota composition, with potential implications for infant health and development.
