Gastric mucosa of horse 50L with erosive gastritis associated with bacteria. Applying a fluorescein labelled probe for Gammaproteobacteria and a Cy3 labelled probe for Enterococcus, an E. coli like organism (green) (arrowhead) was found intracellular within epithelial cells and on the epithelial surface whereas E. faecium (red) ('white star'(only colonised the epithelial surface. Filter set 43/38, bar = 10 μm.
