Chronic wound infections present a prevalent medical issue and a multifaceted problem that significantly impacts healthcare systems worldwide. Biofilms formed by pathogenic bacteria are fundamental virulence factors implicated in the complexity and persistence of bacterial-associated wound infections, leading to prolonged recovery times and increased risk of infection. This study aims to investigate the antibacterial effectiveness of commonly employed bioactive wound healing compositions with a particular emphasis on their effectiveness against common bacterial pathogens encountered in chronic wounds - , , and to identify optimal wound product composition for managing chronic wound infections.
This study tested the antibacterial and antibiofilm effectiveness of four bioactive wound healing materials by performing in vitro antibacterial assays and measuring ion release profiles.
The anti-biofilm effectiveness differed extensively among the biomaterials tested and slightly among the bacterial species. Particularly, copper and zinc-doped borate bioactive glass wound healing compositions inhibited the three clinically relevant bacteria in both planktonic and biofilm forms, which were found to be ascribed to the copper and zinc gradual release.
The findings suggest that copper and zinc-doped bioactive glasses hold great promise for improving chronic wound management by providing strong antibacterial action and promoting faster healing.
慢性伤口感染是一个普遍存在的医学问题,也是一个多方面的难题,对全球医疗系统产生重大影响。由致病细菌形成的生物膜是细菌相关伤口感染的复杂性和持续性的基本毒力因子,导致恢复时间延长和感染风险增加。本研究旨在调查常用的生物活性伤口愈合组合物的抗菌效果,特别强调其对慢性伤口中常见细菌病原体—— 、 和 的有效性,并确定用于管理慢性伤口感染的最佳伤口产品组合物。
本研究通过进行体外抗菌试验和测量离子释放曲线,测试了四种生物活性伤口愈合材料的抗菌和抗生物膜效果。
在所测试的生物材料中,抗生物膜效果差异很大,而在细菌种类之间差异较小。特别是,掺杂铜和锌的硼酸盐生物活性玻璃伤口愈合组合物在浮游和生物膜形式下均抑制了三种临床相关细菌,这被发现归因于铜和锌的逐渐释放。
研究结果表明,掺杂铜和锌的生物活性玻璃通过提供强大的抗菌作用和促进更快愈合,在改善慢性伤口管理方面具有巨大潜力。
