In an investigation of bacterial colonisation of intravascular cannulae, 16 peripheral venous cannulae of the Venflon variety and 24 chronic haemodialysis cannulae were studied after removal from patients. Studies of colonisation included semi-quantitative microbiological culture and scanning electronmicrographic (SEM) observations. The microbiological findings indicated colonisation of the intravascular portion of the catheter in 4 of 16 Venflon cannulae and 18 of 26 haemodialysis cannulae, largely with skin commensal organisms. The results of the SEM studies were in broad agreement with the microbiological observations. Surface defects on the cannulae were shown to be associated with microbial colonisation which occurred either as isolated colonies or in association with a cellular fibrinous matrix. These observations are illustrated and discussed.
在一项关于血管内插管细菌定植的调查中，从患者身上移除了16根Venflon型外周静脉插管和24根慢性血液透析插管并进行研究。定植研究包括半定量微生物培养和扫描电子显微镜（SEM）观察。微生物学研究结果表明，16根Venflon插管中有4根以及26根血液透析插管中有18根的导管血管内部分发生了定植，主要是皮肤共生菌。SEM研究结果与微生物学观察结果基本一致。插管表面缺陷显示与微生物定植有关，微生物定植以孤立菌落形式出现或与细胞纤维蛋白基质相关。文中对这些观察结果进行了说明和讨论。
