Antibiotics can cause pervasive, persistant changes to microbiota in human gut

... several bacterial taxa failed to recover within six months. This raises questions about the health effects of perturbations to the human-microbial symbiosis in the gut, such as may occur with antibiotic treatment. Because specific microbial populations mediate many chemical transformations in the gutand p...

Mechanisms of plant-fungi symbiosis characterized by DOE Joint Genome Institute

WALNUT CREEK, CA, Plants gained their ancestral toehold on dry land with considerable help from their fungal friends. Now, millennia later, that partnership is being exploited as a strategy to bolster biomass production for next generation biofuels. The genetic mechanism of this kind of symbiosis,...
