Bacterial adhesion and colonization

Bacterial adhesion and colonization on the skin is a multi-step biological process where microorganisms, particularly Staphylococcus aureus, establish a persistent presence on the cutaneous surface. This process is primarily mediated by a family of bacterial surface proteins known as Microbial Surface Components Recognizing Adhesive Matrix Molecules (MSCRAMMs), which bind to host extracellular matrix proteins such as fibronectin, collagen, and fibrinogen (Source: Foster et al., Nature Reviews Microbiology, 2014). Successful colonization is a critical virulence factor, serving as a prerequisite for invasive infections and contributing to the pathogenesis of chronic inflammatory skin conditions like atopic dermatitis (Source: Geoghegan et al., 2018, PMID: 29331318). In these diseases, the density of S. aureus often correlates with the severity of skin barrier impairment and inflammation (Source: NIH, National Institute of Allergy and Infectious Diseases). Therapeutic strategies targeting this process aim to reduce bacterial load or prevent the initial attachment of pathogens to host tissues. Topical antibiotics such as mupirocin and retapamulin are commonly employed to decolonize the skin by inhibiting bacterial protein synthesis (Source: StatPearls, Mupirocin). Additionally, antiseptic agents like chlorhexidine provide a broad-spectrum approach to reducing microbial colonization through physical and chemical disruption of bacterial membranes (Source: PubChem). Emerging research is also focused on anti-adhesive therapies, such as monoclonal antibodies or small molecules that specifically block MSCRAMM-ligand interactions, offering a potential way to prevent infection without the selective pressure associated with traditional antibiotics (Source: Nature Reviews Microbiology, 2014).
