Abstract

Thirty-two carbapenem-resistant Klebsiella pneumoniae isolates, representative of different resistance mechanisms and clonal lineages, were analyzed with the Pathogenica HAI BioDetection system, based on targeted next-generation sequencing (NGS) technology. With most strains, the system simultaneously yielded comprehensive information on relevant β-lactam resistance determinants and accurate discrimination of clonal lineages, in a shorter time frame and in a less labor-intensive manner than currently available methods for molecular epidemiology analysis. Results supported the usefulness of targeted NGS-based technologies for similar applications.

摘要

基于靶向新一代测序(NGS)技术,使用Pathogenica HAI生物检测系统对32株耐碳青霉烯类肺炎克雷伯菌分离株进行了分析,这些分离株代表了不同的耐药机制和克隆谱系。对于大多数菌株,该系统能在更短的时间内,以比目前分子流行病学分析方法更低的劳动强度,同时提供有关相关β-内酰胺耐药决定因素的全面信息,并准确区分克隆谱系。结果支持了基于靶向NGS的技术在类似应用中的实用性。
