Nonfermenting gram-negative bacteria and enterobacteria isolated from various biomaterials of patients of the orthopedic trauma hospital with implant-associated infection demonstrated significantly (p<0.05) higher biofilm formation capacity than the reference strains. The differences in biofilm formation kinetics were revealed: biofilm maturation and the beginning of its dispersion after 48-h incubation in enterobacteria and longer biofilm maturation phase in nonfermenting gram-negative bacteria. It was found that the strains isolated from sonication fluid have reliably (p<0.05) higher propensity to biofilm formation than bacteria isolated from aspirate and wound exudate.

种植体相关感染期间革兰氏阴性细菌生物膜的形成

从骨科创伤医院植入物相关感染患者的各种生物材料中分离出的非发酵革兰氏阴性菌和肠杆菌显示出比参考菌株显着(p<0.05)更高的生物膜形成能力。揭示了生物膜形成动力学的差异:在肠杆菌中培养 48 小时后生物膜成熟及其分散的开始,以及非发酵革兰氏阴性菌中更长的生物膜成熟阶段。发现从超声处理液中分离的菌株与从吸出物和伤口渗出液中分离的细菌相比,具有可靠的 (p<0.05) 更高的生物膜形成倾向。
