近年来,在尿路感染的发病机制方面进行了广泛深入的研究,取得了不少新进展,尿路细菌的粘附性研究便是其中之一,运用这方面的研究成果,有助于增强机体抗感染力,减弱细菌致病力,从而减少泌尿系感染的发生。细菌对尿路上皮的粘附致病菌不论从血循或由逆行进入泌尿系,不一定导致尿路感染,这是因为肾盂、输尿管和膀胱的蠕动、收缩功能和尿液的稀释冲洗作用,使细菌在泌尿系停留时间很短。病菌要引起泌尿系炎症,首 In recent years, extensive and in-depth research has been carried out on the pathogenesis of urinary tract infection, and many new advances have been made. The study on the adhesion of urinary tract bacteria is one of them. Using the research results in this respect is helpful to enhance Anti-infective body, reducing bacterial pathogenicity, thereby reducing the incidence of urinary tract infection. Bacteria on the urinary tract epithelial adhesion Pathogenic bacteria, either from the blood or from retrograde into the urinary tract, does not necessarily lead to urinary tract infection, which is due to the renal pelvis, ureter and bladder peristalsis, systolic function and dilution of urine flushing effect, Bacteria in the urinary retention time is very short. Pathogens to cause urinary tract inflammation, the first
