Hypervirulent (hvKP) has spread globally since first described in the Asian Pacific Rim. It is an invasive variant that differs from the classical (cKP), with hypermucoviscosity and hypervirulence, causing community-acquired infections, including pyogenic liver abscess, pneumonia, meningitis, and endophthalmitis. It utilizes a battery of virulence factors for survival and pathogenesis, such as capsule, siderophores, lipopolysaccharide, fimbriae, outer membrane proteins, and type 6 secretion system, of which the former two are dominant. This review summarizes these hvKP-associated virulence factors in order to understand its molecular pathogenesis and shed light on new strategies to improve the prevention, diagnosis, and treatment of hvKP-causing infection.
自首次在亚太地区被描述以来,高毒力肺炎克雷伯菌(hvKP)已在全球范围内传播。它是一种侵袭性变体,与经典肺炎克雷伯菌(cKP)不同,具有高黏液性和高毒力,可引起社区获得性感染,包括化脓性肝脓肿、肺炎、脑膜炎和眼内炎。它利用一系列毒力因子来生存和致病,如荚膜、铁载体、脂多糖、菌毛、外膜蛋白和6型分泌系统,其中前两者占主导地位。本综述总结了这些与hvKP相关的毒力因子,以了解其分子发病机制,并为改善hvKP所致感染的预防、诊断和治疗的新策略提供思路。
