Abstract: The ability of Lactobacillus to adhere to the intestinal epithelium is one of the most important criterion in the selection of probiotic strains. Adherence allows microorganisms to survive and temporarily colonize the digestive system, which is necessary to induce beneficial effects on the host. Adhesion is a very complex, multistep process and, although there are many proposed theories, the exact mechanism is still not fully understood. A crucial role in the formation of the adhesive interactions plays the bacterial cell wall and its components, such as exopolisaccharydes, lipoteichoic acids and various proteins e.g. S-layer proteins.
