Architecture of Intracellular Bacteria.

<p>Female mice were infected with UTI89/pANT4, ROL745/pANT4 (UTI89 <i>ihfA11</i>), ROL603/pANT4 (UTI89 <i>ΔihfB</i>), SJ1000/pANT4 (UTI89 <i>surA</i>), or UTI89 <i>Δkps</i>/pANT4 for 6 hours. Bladders were prepared for visualization by fluorescent microscopy <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0048349#pone.0048349-Justice3" target="_blank">[41]</a>. The intracellular characteristics of each of the strains indicated were visualized using strains that constitutively produce green fluorescent protein. Images were taken as an optical section (upper panel UPEC) or as total fluorescence of entire community (all other panels). The strains are indicated above each panel. Scale bar = 10 µm and scale is unchanged between images.
