A review on anti-adhesion therapies of bacterial diseases
In anti-adhesive therapy, sensitive bacteria are still viable, where resistance to antibiotic therapy has been observed to occur at a much slower rate . By attaching to host cells, bacteria can resist the actions of cleaning mechanisms of the body, allowing the bacteria to reach a density whereby an infection can start.

Adhesive mechanism of different Salmonella fimbrial adhesins
The Salmonella fimbriae are assembled in three types of assembly pathways: chaperon-usher, nucleation-precipitation, and type IV fimbriae. These assembly pathways lead to multiple types of fimbriae. Salmonella fimbriae bind to host cell receptors to initiate adhesion. So far, many receptors have been identified, such as Toll-like receptors.
