Bacteria have their own language through which they communicate with one another like all higher organisms. So, many researchers are working hard to identify and comprehend the components of this bacterial communication, known as quorum sensing (QS). In quorum sensing, bacteria use signaling molecules called autoinducers (AIs) to exchange information. Many natural compounds and extraction techniques have been intensively studied to disrupt bacterial signaling and examine their effectiveness for bacterial pathogenesis control. Quorum sensing inhibitors can interfere with QS and block the action of AI signaling molecules. Recent research indicates that quorum sensing inhibitors (QSIs) and quorum quenching enzymes (QQEs) show great promise in reducing the pathogenicity of bacteria and inhibiting biofilm synthesis. In addition, the effectiveness of QQEs and QSIs in experimental animal models was demonstrated. These are taken into account in the development of innovative medical devices, such as dressings and catheters, to prevent bacterial infections. The present review highlights this aspect with a prospective vision for its development and application.
细菌通过自身的语言与其他高等生物一样相互交流。因此,许多研究人员正在努力识别和理解这种细菌间的通讯方式,即群体感应(QS)。在群体感应中,细菌使用被称为自诱导物(AIs)的信号分子来交换信息。许多天然化合物和提取技术已经被深入研究,以干扰细菌信号传递并研究它们在控制细菌发病机制方面的有效性。群体感应抑制剂可以干扰 QS 并阻断 AI 信号分子的作用。最近的研究表明,群体感应抑制剂(QSIs)和群体感应淬灭酶(QQEs)在降低细菌致病性和抑制生物膜合成方面显示出巨大的潜力。此外,还在实验动物模型中证明了 QQEs 和 QSIs 的有效性。这些都被考虑用于创新型医疗器械的开发,如敷料和导管,以预防细菌感染。本综述以前瞻性的视角突出了这一方面,并对其发展和应用进行了展望。
