Abstract

Carbapenem-resistant Enterobacteriaceae (CRE) are a serious public health threat. Infections due to these organisms are associated with significant morbidity and mortality. Mechanisms of drug resistance in gram-negative bacteria (GNB) are numerous; β-lactamase genes carried on mobile genetic elements are a key mechanism for the rapid spread of antibiotic-resistant GNB worldwide. Transmissible carbapenem-resistance in Enterobacteriaceae has been recognized for the last 2 decades, but global dissemination of carbapenemase-producing Enterobacteriaceae (CPE) is a more recent problem that, once initiated, has been occurring at an alarming pace. In this article, we discuss the evolution of CRE, with a focus on the epidemiology of the CPE pandemic; review risk factors for colonization and infection with the most common transmissible CPE worldwide, Klebsiella pneumoniae carbapenemase-producing K. pneumoniae; and present strategies used to halt the striking spread of these deadly pathogens.

摘要

耐碳青霉烯类肠杆菌科细菌(CRE)是对公共卫生的严重威胁。这些微生物引起的感染与显著的发病率和死亡率相关。革兰氏阴性菌(GNB)的耐药机制众多;移动遗传元件携带的β-内酰胺酶基因是耐药GNB在全球迅速传播的关键机制。肠杆菌科细菌中可传播的碳青霉烯耐药性在过去20年中已得到确认,但产碳青霉烯酶肠杆菌科细菌(CPE)的全球传播是一个较新出现的问题,一旦开始传播,其速度惊人。在本文中,我们讨论CRE的演变,重点关注CPE大流行的流行病学;回顾全球最常见的可传播CPE——产肺炎克雷伯菌碳青霉烯酶的肺炎克雷伯菌的定植和感染风险因素;并介绍用于阻止这些致命病原体惊人传播的策略。
