Microscopic observations of gut microbiota engulfed by phagocytes of specific subsets.

<p>Microscopic observation of each subset was performed at a magnification of 1000 or 630 after Giemsa staining or FISH with a Cy3-conjugated Eub338 probe (total bacteria, red) and TO-PRO^®-3 (nuclei, blue), respectively. Scale bars represent 10 μm.
