title: Xenobiotics and the human gut microbiome: metatranscriptomics reveal the active players.
abstract: The human gut microbiome plays an important role in the metabolism of xenobiotics. In a recent issue of Cell, Maurice et al. (2013) identify the active members of the gut microbiome and show how gene-expression profiles change within the gut microbial community in response to antibiotics and host-targeted xenobiotics.
