We compared association of Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa and Enterococcus faecalis with nine vascular implants after co-culture. Vascular implants were composed of various materials such as warp knitted polyester (with or without gelatin and silver ions), expanded polytetrafluoroethylene and biological materials - surface treated porcine pericardial patch and Omniflow II. The lowest overall number of associated bacteria was detected for polytetrafluoroethylene implants and porcine pericardial patch. The highest overall number of associated bacteria was detected for Omniflow II implant. The major source of variation, i.e. primary factor influencing colonization, is the implant type (56.22%), bacterial species is responsible for only 1.81%, and interaction of those two factors - 13.09% of variation.
我们比较了金黄色葡萄球菌、表皮葡萄球菌、铜绿假单胞菌和粪肠球菌与九种血管植入物共培养后的关联情况。血管植入物由多种材料制成，如经编聚酯（含或不含明胶和银离子）、膨体聚四氟乙烯以及生物材料——表面处理的猪心包补片和Omniflow II。聚四氟乙烯植入物和猪心包补片检测到的相关细菌总数最低。Omniflow II植入物检测到的相关细菌总数最高。变异的主要来源，即影响定植的主要因素，是植入物类型（56.22%），细菌种类仅占1.81%，这两个因素的相互作用占变异的13.09%。
