Antibiotics-induced monodominance of a novel gut bacterial order

Abstract

The bloom of ^U<i>B. ceftriaxensis</i> and a subsequent one of <i>Parabacteroides distasonis</i> demonstrate the existence of monodominance community states in the gut. Our study points to an undiscovered wealth of low abundant but common taxa in the human gut and calls for more highly resolved longitudinal studies, in particular on ecosystem perturbations.
