Biofilm-associated infections persist as a therapeutic challenge in contemporary medicine. The efficacy of antibiotic therapies is ineffective in numerous instances, necessitating a heightened focus on exploring novel anti-biofilm medical strategies. Among these, iminosugars emerge as a distinctive class of compounds displaying promising biofilm inhibition properties.
This study employs an wound infection mouse model to evaluate the effectiveness of PDIA in treating biofilm-associated skin wound infections caused by and . Dermic wounds in mice were infected with biofilm-forming strains, specifically 48 and 5, which were isolated from patients with diabetic foot, and are well-known for their strong biofilm formation. The subsequent analysis included clinical, microbiological, and histopathological parameters. Furthermore, an exploration into the susceptibility of the infectious strains to hydrogen peroxide was conducted, acknowledging its potential presence during induced inflammation in mouse dermal wounds within an model.
The findings revealed the efficacy of PDIA iminosugar against the strain, evidenced by a reduction in bacterial numbers within the wound and the inflammatory focus.
This study suggests that PDIA iminosugar emerges as an active and potentially effective antibiofilm agent, positioning it as a viable treatment option for staphylococcal infections.
生物膜相关感染在当代医学中仍然是一个治疗挑战。在许多情况下,抗生素治疗的效果并不理想,因此需要更加关注探索新型抗生物膜医学策略。其中,亚氨基糖作为一类具有独特结构的化合物,显示出具有前景的抗生物膜特性。
本研究采用皮肤感染小鼠模型,评估 PDIA 在治疗由 和 引起的生物膜相关皮肤伤口感染的效果。将生物膜形成菌株 48 和 5 感染到小鼠的皮肤伤口中,这些菌株是从糖尿病足患者中分离出来的,它们以强生物膜形成能力而闻名。随后分析了临床、微生物学和组织病理学参数。此外,还研究了感染菌株对过氧化氢的敏感性,因为在 模型中,诱导的炎症可能会导致小鼠真皮伤口中存在过氧化氢。
研究结果表明,PDIA 亚氨基糖对 菌株有效,表现为伤口和炎症焦点内细菌数量减少。
本研究表明,PDIA 亚氨基糖作为一种有效的抗生物膜剂,为葡萄球菌感染提供了一种可行的治疗选择。
