Bacterial adhesion sites and biofilm surfaces

Bacterial adhesion sites and biofilm surfaces represent a complex set of therapeutic targets involved in the establishment and persistence of microbial infections. Adhesion sites are primarily composed of bacterial adhesins, such as fimbriae and pili, which facilitate attachment to host cell receptors or abiotic surfaces (PubMed: 29026254). Biofilms are structured communities of bacteria embedded within a self-produced extracellular polymeric substance (EPS) matrix, which includes polysaccharides, proteins, and extracellular DNA (eDNA) (NIH: PMC3183659). This matrix acts as a protective barrier against antibiotics and the host immune system, contributing to the chronicity of infections like cystic fibrosis and medical device-related complications (PubMed: 21884612). Drugs targeting these sites include adhesin inhibitors like mannosides and matrix-degrading enzymes like dornase alfa (PubChem: CID 60196). Effective management of biofilms is a major challenge in modern medicine due to the high level of tolerance exhibited by sessile bacterial populations compared to their planktonic counterparts.
