title: Bacteria Come into Focus: New Tools for Visualizing the Microbiota.
abstract: Humans are home to complex communities of microbes that profoundly influence host physiology. Two recent papers, including Earle et al. (2015) in this issue of Cell Host & Microbe, contribute new experimental tools for visualizing and tracking bacteria within a host, promising to shed light on how microbes interact to influence host health.
