The team\u2019s results show that bacteria from the mother are more likely to colonize newborns compared with bacteria from the surrounding environment, and that the maternal bacteria are more persistent.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">25 mother-child pairs<\/h2>\n\n\n\n<p>The study involved 25 mother-child pairs. Microbiome samples were collected from different body sites of the mothers before they gave birth: from the skin, tongue, faeces and vagina. After birth, samples of the newborns\u2019 faeces and tongue were collected. The team examined the samples to identify and map microorganisms &#8211; and their transmissions from mother to child &#8211; using metagenomics and bioinformatics.<\/p>\n\n\n\n<p>\u201cOur study provides the foundation for a better understanding of the microbiome acquisition process, its impact on the child\u2019s health, and the role of natural childbirth, breastfeeding and skin-to-skin contact\u201d, says project leader Nicola Segata, a Professor at the University of Trento. \u201cThis opens interesting scenarios because the preference for maternal microorganisms in infants may suggest that there is a co-evolutionary mechanism that has remained largely unexplored so far\u201d.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Unknown species<\/h2>\n\n\n\n<p>Another intriguing aspect is that some of the bacteria passed on from mother to child belong to unknown bacterial species: \u201cIt is crucial to characterise these unknown bacteria through targeted experiments to understand their specific role in the child\u2019s health\u201d, says first author Pamela Ferretti, previously at the University of Trento and now PhD student in the Bork group at EMBL.<\/p>\n\n\n\n<p>Now that the researchers have learned which microorganisms pass from mother to infant and how they do it, they want to better understand their impact on the child\u2019s health. For example, how the transmission of the maternal microbiome is affected by factors such as C-section delivery, lack of skin contact between mother and child in the first instants of life, and feeding with infant formula. A potential future application of the research could be to provide children with microorganisms that they do not receive from their mothers for one of the above reasons.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists show how bacteria and other microorganisms are passed on from mother to child<\/p>\n","protected":false},"author":58,"featured_media":13885,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[2,17591],"tags":[580,365,673,672],"embl_taxonomy":[],"class_list":["post-13883","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-science","category-science-technology","tag-bacteria","tag-bork","tag-mother","tag-newborn"],"acf":{"article_intro":"<p>During the first moments of a baby\u2019s life, bacteria and other microorganisms are passed from the mother.
