WebAdhesins are found on bacterial, viral, fungal, and protozoan pathogens. One example of a bacterial adhesin is type 1 fimbrial adhesin, a molecule found on the tips of fimbriae of enterotoxigenic E. coli ( ETEC ). Recall that fimbriae are … WebBacterial, viral and parasitic pathogens use adhesins to bind to individual host cells and establish interactions with host molecules, thereby initiating colonization. The exact nature of the interaction between pathogen surface molecules and cell receptors defines the cellular or tissue specificity. WebBacteria often express multiple adhesive proteins (adhesins), but it is often unclear whether adhesins have specialized or redundant roles. Here, we show how the model biofilm-forming organism Vibrio cholerae uses two adhesins with overlapping but distinct functions to achieve robust adhesion to diverse surfaces.
