Document Summary
Infant colonisation: infants are born sterile, colonisation of the infant is from humans (skin- skin contact) and the environment, hormonal response in parents to skin-skin contact leading to parent-child bonding. Bifidobacterium the most abundant group in the infant gut. Thats why always in infant food formula. Bacteroidetes and infant colonisation: bacteroides induce mucus-utilization genes to consume human milk oligosaccharides, lacto-n-neotetraose selects for bifidobacteria relative to bacteroides in vivo (bt) (b. infantis) Carnivore herbivore diets meat eaters (carnivores) have shorter intestines. 30% less diet intake will live slightly longer took 33 mammals and 18 humans in to a constrained diet. Want to know what genes were expressed to look at what the microbes did. Carnivore - herbivore diets: adaptation of the microbiota to diet is similar across different mammalian lineages. Functional genes, such as those encoding carbohydrate- active enzymes and proteases, can be predicted from bacterial species assemblages what they were able to show:
