How might microorganisms move from one part of the body to another? Let's begin with the womb, where the concept of fetal colonization has rapidly gained acceptance, indicated by meconium and placental microbe studies.

In this study, researchers characterized the gut microbiota of breastfeeding mothers after collecting fecal samples from 2 days to 6 months postpartum. They found that the women's gut bacterial communities were similar to those found in other adults; the gut

As MyNewGut, a research initiative involving thirty organizations from fifteen countries, continued to carry out its research program on prebiotic fibres and the gut microbiota, project participants held a workshop before the International Dietary Fibre Conference 2015 in Paris.

Liping Zhao and colleagues, in their recent paper on a dietary intervention for simple and genetic obesity, discussed evidence for the existence of gut microbiota 'guilds': bacterial genomes within the gut ecosystem that responded to the dietary intervention as a group.

Previous research has shown that adults with irritable bowel syndrome (IBS) who adopt a low FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) diet show an improvement in symptoms within 2 days. Would the low FODMAP diet have the same effect in childhood IBS? Does the gut microbiota predict the success of the diet in children who respond to this dietary intervention?
