Bacterial adhesion is the process by which bacteria attach to surfaces, such as host tissues or medical devices, in order to colonize and form biofilms. This adhesion is a crucial step in the pathogenesis of bacterial infections, as it allows bacteria to resist removal by natural defenses or antimicrobial agents. Understanding the mechanisms of bacterial adhesion can help in developing strategies to prevent or disrupt these interactions, thereby reducing the incidence of bacterial infections. Research in this area often focuses on identifying the specific adhesion molecules involved, the factors that influence adhesion, and potential therapeutic targets for intervention.
