Biofilm formation is a major concern in various sectors and cause severe problems to public health, medicine, and industry. Bacterial biofilm formation is a major persistent threat, as it increases morbidity and mortality, thereby imposing heavy economic pressure on the healthcare sector. Bacterial biofilms also strengthen biofouling, affecting shipping functions, and the offshore industries in their natural environment. Besides, they accomplish harsh roles in the corrosion of pipelines in industries. At biofilm state, bacterial pathogens are significantly resistant to external attack like antibiotics, chemicals, disinfectants, etc. Within a cell, they are insensitive to drugs and host immune responses. The development of intact biofilms is very critical for the spreading and persistence of bacterial infections in the host. Further, bacteria form biofilms on every probable substratum, and their infections have been found in plants, livestock, and humans. The advent of novel strategies for treating and preventing biofilm formation has gained a great deal of attention. To prevent the development of resistant mutants, a feasible technique that may target adhesive properties without affecting the bacterial vitality is needed. This stimulated research is a rapidly growing field for applicable control measures to prevent biofilm formation. Therefore, this review discusses the current understanding of antibiotic resistance mechanisms in bacterial biofilm and intensely emphasized the novel therapeutic strategies for combating biofilm mediated infections. The forthcoming experimental studies will focus on these recent therapeutic strategies that may lead to the development of effective biofilm inhibitors than conventional treatments.
生物膜形成是各个领域的主要关注点,会给公共卫生、医学和工业带来严重问题。细菌生物膜的形成是一个主要的持续性威胁,因为它会增加发病率和死亡率,从而给医疗保健部门带来沉重的经济压力。细菌生物膜还会加剧生物污损,影响航运功能以及自然环境中的近海产业。此外,它们在工业管道腐蚀中也起着恶劣作用。在生物膜状态下,细菌病原体对诸如抗生素、化学物质、消毒剂等外部攻击具有显著抗性。在细胞内部,它们对药物和宿主免疫反应不敏感。完整生物膜的形成对于细菌感染在宿主体内的传播和持续存在至关重要。此外,细菌会在每一个可能的基质上形成生物膜,并且已经在植物、牲畜和人类中发现了它们引发的感染。治疗和预防生物膜形成的新策略的出现引起了广泛关注。为了防止抗性突变体的产生,需要一种可行的技术,该技术可以靶向粘附特性而不影响细菌活力。这种激励性的研究是一个快速发展的领域,旨在寻找适用的控制措施来防止生物膜形成。因此,本综述讨论了当前对细菌生物膜中抗生素抗性机制的理解,并着重强调了对抗生物膜介导感染的新型治疗策略。即将开展的实验研究将聚焦于这些最新的治疗策略,这些策略可能会开发出比传统治疗方法更有效的生物膜抑制剂。
