In a previous GMFH article, ‘PROBIOTICS’ PART I: A BRANCHING DEFINITION, we covered recent updates to the definition of probiotics as discussed at the October 2013 meeting organized by The International Scientific Association for Probiotics and Prebiotics (ISAPP). Three of the scientific experts on the ISAPP panel – Dr. Francisco Guarner (University Hospital Vall d’Hebron, Barcelona, Spain), Dr. Mary Ellen…

Researchers from Israel recently published in Nature how NAS [Non-caloric artificial sweeteners] affect glucose tolerance. In an initial experiment, researchers found mice that consumed water, glucose, or sucrose had comparable glucose tolerance curves, but all 3 mouse groups consuming NAS (either saccharin, sucralose, or aspartame) developed marked glucose intolerance. They focused on saccharin for the next series of experiments, since…

Patrick Veiga and MetaHIT colleagues tested how fermented milks product could modulate microbiota. Using a metagenomics approach, they found that the abundance of unknown species increased in the gut when patients took the fermented milk product. Having access to the functional content, authors found that those species had the functional potential to produce butyrate. Patrick Veiga accepted to give us…

In Science Report journal, Zhang and colleagues published a study about Mongolians known to have their own typical lifestyle, notably in terms of dietary habits. Using 16S rDNA pyrosequencing, researchers showed the presence of a phylogenetic core microbiota comprising the genera Prevotella, Bacteroides, Faecalibacterium, Ruminococcus, Subdoligranulum and Coprococcus. They have shown that urbanisation may change the composition of their gut…

Stefka and colleagues studied whether food allergy could be affected by gut microbiota. Germ-free, antibiotic treated and conventional mice have been exposed to a peanut allergen. They found that sensitization to the allergen increased in germ free and antibiotic treated mice. Using a a mix of Clostridia strains, they reversed the sensitization process and demonstrate that this mix could minimize…

Stein and colleagues describe in their study, published in PLOS computational biology, how time series can help to study dynamics of the microbiota. Moreover, unlike usual cross sectional studies which lack a mechanistic understanding of the ecosystem's structure and its response to external perturbations, modelling dynamics can help to predict and recover the microbiota temporal dynamics. For example, they modeled…
