New approaches to control infections: Anti-biofilm strategies against gramnegative bacteria

Abstract

Hospital-acquired bacterial infections, especially with Gram-negative pathogens, present a major threat due to the rapid spread of antibiotic-resistant strains. Targeting mechanisms of bacterial virulence has recently appeared as a promising new therapeutic paradigm. Biofilm formation is a bacterial lifestyle, which offers a survival advantage through its protective matrix against host immune defense and antibiotic treatment. Interfering with biogenesis of adhesive organelles, bacterial communication or carbohydrate-mediated adhesion as anti-biofilm strategies are reviewed. © Schweizerische Chemische Gesellschaft.
