Article Summary: Most Gram-negative bacteria have fimbriae; hair-like projections, external to the cell wall, that allow bacteria to stick to the cells they infect.t the end of each fimbria are special proteins called adhesins. The specific type of adhesin varies by type of bacteria, but regardless of the type, adhesin molecules allow bacteria with fimbriae to adhere to host cells by docking, like a lock and key, with receptor proteins on the surface of host epithelial cells.
