The Gram-positive coccus, Staphylococcus aureus, is the leading etiologic agent of limb and life-threatening biofilm-related infections in the patients following the orthopaedic implantations. The aim of the present paper is to estimate the ability of S. aureus to form biofilm on titanium alloy (Ti-6Al-7Nb) scaffolds produced by Selective Laser Melting (SLM) and subjected to the different types of surface modifications, including ultrasonic cleaning and chemical polishing. The results obtained indicate significantly the decreased ability of S.aureus to form biofilm on the surface of scaffolds subjected to the chemical polishing in comparison to the scaffolds cleaned ultrasonically. The data provided can be useful for future applications of the SLM technology in production of Ti-6Al-7Nb medical implants.
革兰氏阳性球菌金黄色葡萄球菌是骨科植入术后患者肢体及危及生命的生物膜相关感染的主要病原体。本文旨在评估金黄色葡萄球菌在通过选择性激光熔化（SLM）制备并经过不同类型表面改性（包括超声清洗和化学抛光）的钛合金（Ti-6Al-7Nb）支架上形成生物膜的能力。所得结果表明，与超声清洗的支架相比，经过化学抛光的支架表面上金黄色葡萄球菌形成生物膜的能力显著降低。所提供的数据对于SLM技术在Ti-6Al-7Nb医用植入物生产中的未来应用可能有用。
