Pathogenic microorganisms at intestinal mucosal adhesion sites

Pathogenic microorganisms at intestinal mucosal adhesion sites represent a complex biological interface rather than a single molecular entity. This site involves the interaction between microbial adhesins, such as pili or fimbriae, and host-cell surface receptors, including glycoproteins and glycolipids [Pizarro-Guajardo et al., 2016, Frontiers in Cellular and Infection Microbiology]. The adhesion process is a critical initial step for enteric pathogens like Escherichia coli, Salmonella, and Clostridioides difficile to colonize the gut, deliver toxins, and invade host tissues [Oelschlaeger, 2010, International Journal of Medical Microbiology]. Therapeutic strategies targeting this interface, known as anti-adhesion therapies, aim to prevent infection by blocking these specific binding interactions using decoy receptors, small molecule inhibitors, or competitive probiotics [Ofek et al., 2003, Trends in Microbiology]. Unlike traditional antibiotics, these interventions often focus on neutralizing virulence factors without killing the bacteria, which may help preserve the commensal microbiota and reduce the selection pressure for antibiotic resistance [Asadi et al., 2019, Microbial Pathogenesis]. Consequently, this target area is of significant interest for treating diarrheal diseases and managing chronic conditions like Crohn's disease where bacterial adhesion plays a role in pathogenesis [Enterome, 2023].
