Adhesion to the human gut epithelium is essential for the beneficial effects of probiotics.
A human organoid-derived intestinal epithelial cell (IEC) monolayer model recapitulateskey features of the gut epithelium and overcomes limitations of three-dimensionalcultures, providing a suitable platform for assessing bacterial adhesion. In this study, weevaluated the adhesion capacity of the probiotic strain Lactobacillus gasseri BNR17 to humanIECs using fluorescence-based analysis and colony-forming unit assays. BNR17 retainedhigh fluorescence intensity after washing and exhibited approximately 20-fold greaterviable adhesion than the control strain Limosilactobacillus fermentum ACE21. These resultsdemonstrate the strong adhesive capacity of L. gasseri BNR17, supporting its potential foreffective gut colonization and health promotion.
