Abstract

Carbapenem-resistant Acinetobacter baumannii (CRAB) is a top-priority pathogen causing a nosocomial infection that increases morbidity and mortality. Treatment options for CRAB are relatively limited by pharmacokinetic restrictions, such as substantial toxicity. Therefore, we must better understand this pathogen to develop new treatments and control strategies. The review aims to provide an overview of the current understanding of acquired, adaptive, and intrinsic Carbapenem-resistant pathways in A. baumannii, as well as its consequences on healthcare systems, particularly critical care units. The review also provides insights into how CRAB infections are currently managed worldwide and why novel therapeutic regimens are needed. The peculiarity of A. baumannii and its often reported virulence factors have been discussed further. In conclusion, the purpose of this review is to emphasize the current knowledge on CRAB, as it causes major worry in the field of nosocomial infections as well as overall public health.

耐碳青霉烯类鲍曼不动杆菌引起全球对新抗生素方案的警惕

耐碳青霉烯类鲍曼不动杆菌（CRAB）是引起院内感染的首要病原体，会增加发病率和死亡率。由于药代动力学的限制，CRAB 的治疗方案相对有限，例如严重的毒性。因此，我们必须更好地了解这种病原体，以开发新的治疗方法和控制策略。本综述旨在概述目前对鲍曼不动杆菌的获得性、适应性和固有卡巴培南耐药途径的了解，以及其对医疗保健系统（尤其是重症监护病房）的影响。本综述还深入探讨了目前全球是如何处理 CRAB 感染的，以及为什么需要新的治疗方案。此外，还进一步讨论了鲍曼不动杆菌的特殊性及其经常报道的毒力因子。总之，这篇综述的目的是强调目前有关 CRAB 的知识，因为它在医院内感染领域和整个公共卫生领域都引起了极大的担忧。

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
