This study aimed to investigate the molecular epidemiology of carbapenem-resistant hypervirulent (CR-hvKP) ST23 in China. We conducted comprehensive searches across five databases (PubMed, Web of Science, MEDLINE, CNKI, and Wanfang) spanning 1980-2024, identifying 30 eligible studies through rigorous screening. Our synthesis documents 120 ST23 CR-hvKP clinical isolates, including the earliest known case from Zhejiang in 2013 which harbored alongside hallmark virulence loci (, , , , and ). Epidemiological analysis of 119 isolates reveals geographic disparities: Hebei (25.2%) and Jiangxi (22.7%) are hotspots, while carbapenemase distribution exhibits a north-south divide ( predominating in northern China versus in the south). Phylogenetic analysis of 584 global ST23 genomes suggests independent plasmid-mediated acquisition of carbapenemase genes, with evidence of clonal transmission both among humans and between humans and environmental niches. This review highlights the urgent need for surveillance to track CR-hvKP's evolving epidemiology, alongside interventions targeting plasmid-driven resistance spread.
本研究旨在调查中国耐碳青霉烯类高毒力肺炎克雷伯菌(CR-hvKP)ST23的分子流行病学。我们对1980年至2024年期间的五个数据库(PubMed、Web of Science、MEDLINE、中国知网和万方)进行了全面检索,通过严格筛选确定了30项符合条件的研究。我们的综合分析记录了120株ST23 CR-hvKP临床分离株,包括2013年来自浙江的最早已知病例,该病例携带了标志性毒力基因座(、、、和)。对119株分离株的流行病学分析揭示了地理差异:河北(25.2%)和江西(22.7%)是热点地区,而碳青霉烯酶分布呈现南北差异(在中国北方占主导地位,而在南方占主导地位)。对584个全球ST23基因组的系统发育分析表明,碳青霉烯酶基因是通过质粒介导独立获得的,有证据表明在人类之间以及人类与环境生态位之间存在克隆传播。本综述强调了迫切需要进行监测以追踪CR-hvKP不断演变的流行病学,同时需要采取针对质粒驱动的耐药性传播的干预措施。
