Deciphering the virulence factors, regulation, and immune response to infection is a gram-negative multidrug-resistant nosocomial pathogen and a major cause of hospital acquired infetions. Carbapenem resistant has been categorised as a Priority1 critial pathogen by the World Health Organisation. is responsible for infections in hospital settings, clinical sectors, ventilator-associated pneumonia, and bloodstream infections with a mortality rates up to 35%. With the development of advanced genome sequencing, molecular mechanisms of manipulating bacterial genomes, and animal infection studies, it has become more convenient to identify the factors that play a major role in infection and its persistence. In the present review, we have explored the mechanism of infection, virulence factors, and various other factors associated with the pathogenesis of this organism. Additionally, the role of the innate and adaptive immune response, and the current progress in the development of innovative strategies to combat this multidrug-resistant pathogen is also discussed.
解析其毒力因子、调控机制以及感染免疫应答,该菌是一种革兰氏阴性、多重耐药的医院获得性病原体,也是医院获得性感染的主要原因。耐碳青霉烯肠杆菌科细菌已被世界卫生组织列为第一类关键病原体。该菌可导致医院环境、临床科室、呼吸机相关性肺炎和血流感染,死亡率高达 35%。随着先进基因组测序技术、细菌基因组操作的分子机制以及动物感染研究的发展,鉴定在感染及其持续存在中起主要作用的因素变得更加便捷。本综述探讨了该菌的感染机制、毒力因子以及与该病原体发病机制相关的各种其他因素。此外,还讨论了固有和适应性免疫应答的作用,以及开发创新策略来对抗这种多重耐药病原体的最新进展。
