In animal models and human trials, Lactobacillus gasseri OLL2716 (LG21) strain suppressed Helicobacter pylori colonization in the stomach. The aim of the present study was to clarify whether orally administered LG21 strain can enter the gastric mucus layer. Biopsy samples were taken from the gastric antrum and corpus of two healthy volunteers (H. pylori infected and non-infected) who drank yogurt supplemented with LG21 strains. DNA of LG21 and H. pylori in the mucus layer was detected using the laser-assisted microdissection and non-contact pressure catapulting (LMPC) method and the semi-nested PCR method with primer sets of RNA helicases of superfamily II gene-Insertion sequence for LG21 strain and those of ureA gene for H. pylori. In the volunteer with H. pylori infection, DNA fragments of LG21- and H. pylori-specific regions from both antrum and corpus were amplified, whereas in a non-infected volunteer, only the LG21 DNA from the antrum was amplified. The present study demonstrated that LG21 strains administered through a yogurt drink can enter into the gastric mucus layer. Our novel method may be useful in studying gastric probiotics for H. pylori infection.
