表皮葡萄球菌(Staphylococcus epidermidis,Se)是临床医疗中重要的条件致病菌,近年来Se的感染率不断上升,已成为医院感染的重要病原菌之一。导致Se致病的主要原因是其形成可黏附于临床常用的聚合物材料上的生物被膜(bio-film),抵抗抗生素的作用并逃避宿主免疫系统的监控,使感染呈现持续性和反复性的特点[1]。本研究就Se生物被膜形 Staphylococcus epidermidis (Se) is an important opportunistic pathogen in clinical practice. The infection rate of Se has been increasing in recent years and has become one of the important pathogens in nosocomial infections. The main cause of Se’s disease is the formation of bio-films that adhere to the most commonly used polymer materials, resist the effects of antibiotics and evade the surveillance of the host’s immune system, making the infection persistent and recurrent Features [1]. Se biomembrane was studied in this study
