Carbapenemase-producing Enterobacteriaceae (CPE) are an important and increasing threat to global health. Both clonal spread and plasmid-mediated transmission contribute to the ongoing rise in incidence of these bacteria. Among the 4 classes of β-lactamases defined by the Ambler classification system, the carbapenemases that confer carbapenem resistance in Enterobacteriaceae belong to 3 of them: Class A (K. pneumoniae carbapenemases, KPC), Class B (metallo-β-lactamases, MBL including New Delhi metallo-β-lactamases, NDM) and Class D (OXA-48-like carbapenemases). KPC-producing CPE are the most commonly occurring CPE in the United States. MBL-producing CPE have been most commonly associated with the Indian Subcontinent as well as with specific countries in Europe, including Romania, Denmark, Spain, and Hungary. The epicenter of OXA-48-like-producing is in Turkey and surrounding countries. Detailed knowledge of the epidemiology and molecular characteristics of CPE is essential to stem the spread of these pathogens.
产碳青霉烯酶肠杆菌科细菌(CPE)对全球健康构成了重要且日益严重的威胁。克隆传播和质粒介导的传播都导致了这些细菌发病率的持续上升。在 Ambler 分类系统定义的 4 类β-内酰胺酶中,赋予肠杆菌科细菌碳青霉烯耐药性的碳青霉烯酶属于其中 3 类:A 类(肺炎克雷伯菌碳青霉烯酶,KPC)、B 类(金属β-内酰胺酶,MBL 包括新德里金属β-内酰胺酶,NDM)和 D 类(OXA-48 样碳青霉烯酶)。在美国,产 KPC 的 CPE 最为常见。产 MBL 的 CPE 最常与印度次大陆以及欧洲的特定国家相关,包括罗马尼亚、丹麦、西班牙和匈牙利。产 OXA-48 样碳青霉烯酶的中心在土耳其及其周边国家。详细了解 CPE 的流行病学和分子特征对于阻止这些病原体的传播至关重要。
