A scanning and transmission electron microscopic study was made of material from the surface of a Foley catheter removed from an 87-year-old woman with antibiotic-resistant bacteriuria. A thick, adherent bacterial biofilm was found. The sessile adherent bacteria were surrounded by an extensive exopolysaccharide glycocalyx that appears to be fundamental in the pathogenesis of catheter-associated urinary tract infections and their resistance to systemic antibiotic therapy.
对一名患有耐抗生素菌尿症的87岁女性所使用的Foley导尿管表面材料进行了扫描电子显微镜和透射电子显微镜研究。发现了一层厚厚的、附着的细菌生物膜。固着的附着细菌被广泛的胞外多糖糖萼所包围，这似乎在导尿管相关尿路感染的发病机制及其对全身抗生素治疗的耐药性中起着重要作用。
