Human nutrition, the gut microbiome, and immune system: envisioning the future
Intriguingly, metagenomic studies of bacterial composition in the fecal microbiota of obese and lean twin pairs living in the USA have shown that obesity is associated with decreased numbers of bacterial species 3. While these antibodies have specificity for components of the microbiota, the microbial targets are not well defined for given maternal- infant dyads, or as a function of time after delivery
