Adhesins are protein cell surface components or appendages of bacteria that enable adhesion to host cell receptors and adhesion surfaces. The most common targets (receptors) are various glycoproteins and sugar residues such as the mannose receptor. The aim of this work was to compare different adhesins between pathogenic bacteria Salmonella, Escherichia and Campylobacter. Fimbrial adhesins are the most abundand and play the major role in ireversible adhesion to the surface. Bacteria of the genus Campylobacter do not have fimbriae (they have not yet been discovered), so the comparison between them was not possible. The similarity between adhesins that adhere to target molecules such as fibronectin, laminin and mannose was discovered. We concluded that adhesins represent a new potential control strategy to interfere with pathogenic bacteria. The target molecules can be replaced by different substances. Furthermore, we discovered that all the mentioned bacteria have expressed flagella, which contributes to adhesion. All adhesins represent a specific expression of individual bacteria.
