Biofilms play a crucial role in persistent infections and antibiotic resistance owing to their structural complexity and protective matrices. This review focuses on current antibiofilm techniques to avoid or inhibit microbial colonisation. Key approaches involve the employing of antimicrobial peptides, quorum sensing inhibitors, quorum quenching agents, matrix-degrading enzymes, nanoparticles, and bacteriophages. These techniques inhibit biofilm formation, increase antimicrobial penetration, and impede biofilm integrity. The focus is on Pseudomonas aeruginosa and Staphylococcus aureus, two clinically relevant biofilm-forming bacteria. Quorum quenching, which interrupts microbial communication networks, has emerged as a viable technique for inhibiting pathogenesis and biofilm growth. Efforts have been made to identify various compounds used for inhibiting quorum Sensing. Various plant extracts and enzymes have been proven to affect quorum sensing profoundly. Another strategy is to inhibit the genes responsible for biofilm formation. Certain genes can be upregulated or downregulated to prevent biofilm formation, or component production can be minimised. A multidisciplinary strategy that incorporates these tactics can give effective approaches for treating biofilm-related illnesses in healthcare and industrial settings.
由于生物膜的结构复杂性和保护性基质,它们在持续性感染和抗生素耐药性中起着至关重要的作用。本综述聚焦于当前避免或抑制微生物定植的抗生物膜技术。关键方法包括使用抗菌肽、群体感应抑制剂、群体猝灭剂、基质降解酶、纳米颗粒和噬菌体。这些技术可抑制生物膜形成、增加抗菌药物的渗透并破坏生物膜的完整性。重点关注铜绿假单胞菌和金黄色葡萄球菌这两种临床上与生物膜形成相关的细菌。群体猝灭通过中断微生物通讯网络,已成为一种抑制发病机制和生物膜生长的可行技术。人们已努力鉴定用于抑制群体感应的各种化合物。各种植物提取物和酶已被证明能深刻影响群体感应。另一种策略是抑制负责生物膜形成的基因。某些基因可被上调或下调以防止生物膜形成,或者其成分的产生可被最小化。结合这些策略的多学科方法可为医疗保健和工业环境中治疗生物膜相关疾病提供有效的途径。
