Figure 3. Ex vivo verification of C. difficile using a fluorescence labelled C. difficile specific probe in CDI.

Figure 3

Panel A shows a characteristic endomicroscopic image of a patient with C. difficile-infection after exposure of the biopsy to the labelled probe and subsequent CLE analysis. Intramucosal bacteria were clearly visible (white spots). Fluorescence in situ hybridization (FISH) confirmed the presence of intramucosal bacteria in this patient due to the bright red fluorescence. Nuclei and DNA are displayed in blue (Panel B). Panel C shows FISH in a control patient without C. difficile infection. No bacteria could be visualized.
