Individualized mosaics of microbial strains transfer from the maternal to the infant gut

Microbial communities in the intestine—also known as the gut microbiome—are vital for human digestion, metabolism and resistance to colonization by pathogens. The gut microbiome composition in infants and toddlers changes extensively in the first three years of life. But where do those microbes come from in the first place? Scientists have long been able to analyze the gut microbiome at the level of the 500 to 1,000 different bacterial species that mainly have a beneficial influence; only more recently have they been able to identify individual strains within a single species using powerful genomic tools and supercomputers that analyze massive amounts of genetic data.  Read more.....
