Detection of <i>H</i>. <i>pylori SS1</i> in frozen sections of gastric mucosa from mice subjected to FIVH, 30 min before euthanasia.

<p>A and B: mice from group V (0.5 μM of the Cy3_HP_LNA/2OMe_PS probe), C and D: group VI (2 μM of the Cy3_HP_LNA/2OMe _PS probe). Arrows indicate the presence of <i>H</i>. <i>pylori</i> infecting the gastric mucosa. All images were taken at equal exposure times, with overlapping of the red, green and DAPI channels. All the images from each group are representative of <i>n</i> = 6 mice. A and C- scale bars: 50 μm. B and D- scale bars: 10 μm.
