This review summarizes research on the human milk microbiome, highlighting its importance for infant health. Human milk contains a diverse range of microorganisms, including bacteria, viruses, fungi, and protozoa, which may influence the development of the infant's microbiome. The microbiome of human milk is influenced by various factors, including the mother's skin, digestive tract, and the infant's oral cavity. The bacteria in human milk may originate from the mother's skin, the infant's mouth, or the mother's digestive tract, and can be transferred to the infant through breastfeeding. The composition of the human milk microbiome varies depending on the stage of lactation, the mother's health, diet, and other factors. The microbiome of human milk has a significant impact on the infant's health, including the development of the immune system and the risk of infections. The review also discusses the potential benefits of human milk as a source of probiotics and prebiotics, which can support the growth of beneficial bacteria in the infant's gut. The study emphasizes the need for further research to better understand the factors that influence the human milk microbiome and its impact on infant health.This review summarizes research on the human milk microbiome, highlighting its importance for infant health.
