Staphylococcus aureus and Staphylococcus epidermidis are a frequent cause of biofilm-associated infections that are a tremendous burden on our healthcare system. Staphylococcal biofilms exhibit extraordinary resistance to antimicrobial killing, limiting the efficacy of antibiotic therapy, and surgical intervention is often required to remove infected tissues or implanted devices. Recent work has provided new insight into the molecular basis of biofilm development in these opportunistic pathogens. Extracellular bacterial products, environmental conditions, and polymicrobial interactions have all been shown to influence profoundly the ability of these bacteria to colonize and disperse from clinically relevant surfaces. We review new developments in staphylococcal biofilm disassembly and set them in the context of potential strategies to control biofilm infections.
金黄色葡萄球菌和表皮葡萄球菌是生物膜相关感染的常见原因,给我们的医疗保健系统带来了巨大的负担。葡萄球菌生物膜表现出非凡的抗微生物杀伤能力,限制了抗生素治疗的效果,通常需要手术干预来去除感染的组织或植入的设备。最近的研究工作为这些机会性病原体生物膜发育的分子基础提供了新的见解。已经证明,细胞外细菌产物、环境条件和多微生物相互作用都深刻地影响了这些细菌在临床上相关表面定植和分散的能力。我们综述了葡萄球菌生物膜解体的新进展,并将其置于控制生物膜感染的潜在策略的背景下。
