A new article published in Nature reveals new information about the link between gut microbiota and infant development, evolution and the transition from infancy to childhood.

Two studies led by Spanish scientists from the Spanish National Research Council (CSIC) and published in the Nature group journals Scientific Report and ISME Journal, respectively, have, for the first time, quantified and classified the effects of some disorders on our gut microbiota based on studies of the substances produced by bacteria when decomposing food molecules, the metabolites.

Results published in the October issue of mBIO magazine showed an imbalance in the ratio of the two largest groups of microorganisms in the human gut (Firmicutes and Bacteroidetes) in favour of Bacteriodetes, while the overall bacterial load and diversity was similar between patients and controls.
