Credit: S. Schuller. Wellcome Images
Colonic crypts infected by a diarrhoeagenic pathogen. The bacteria synthesize a receptor (green) which moves into the intestinal cell membrane and mediates the attachment of the bacteria to the intestinal epithelium. Cell nuclei and bacterial DNA are stained red. The bacteria appear as tiny red dots in amongst the green staining.
