is a leading cause of nosocomial infections due to its increased antibiotic resistance and virulence. The ability of to form biofilms contributes to its survival in adverse environmental conditions including hospital environments and medical devices. has undoubtedly propelled the interest of biomedical researchers due to its broad range of associated infections especially in hospital intensive care units. The interplay among microbial physicochemistry, alterations in the phenotype and genotypic determinants, and the impact of existing ecological niche and the chemistry of antimicrobial agents has led to enhanced biofilm formation resulting in limited access of drugs to their specific targets. Understanding the triggers to biofilm formation is a step towards limiting and containing biofilm-associated infections and development of biofilm-specific countermeasures. The present review therefore focused on explaining the impact of environmental factors, antimicrobial resistance, gene alteration and regulation, and the prevailing microbial ecology in biofilm formation and gives insights into prospective anti-infective treatments.
由于其抗生素耐药性和毒力增加,它是医院感染的主要原因。它形成生物膜的能力有助于其在包括医院环境和医疗设备在内的不利环境条件下生存。由于其广泛的相关感染,尤其是在医院重症监护病房,它无疑激发了生物医学研究人员的兴趣。微生物物理化学、表型和基因型决定因素的改变,以及现有生态位和抗菌剂化学的影响之间的相互作用导致生物膜形成增强,从而使药物难以到达其特定靶点。了解生物膜形成的触发因素是限制和控制生物膜相关感染以及开发生物膜特异性对策的一步。因此,本综述着重解释环境因素、抗菌耐药性、基因改变和调控以及当前微生物生态学对生物膜形成的影响,并深入探讨前瞻性抗感染治疗方法。
