Illustration of the molecular handshake that drives Staphylococcus aureus adhesion to human skin. The bacterial adhesin SdrD (purple) binds tightly to the host receptor desmoglein-1 (DSG-1, orange) on keratinocytes, with calcium ions (Ca²⁺) stabilizing the interaction. This calcium-dependent binding allows S. aureus to attach strongly to the skin surface, providing a molecular explanation for the bacterium's ability to resist mechanical forces and establish infection.
