从波多黎各返回多米尼加共和国的旅行者中携带的耐多药肺炎克雷伯菌 ST307。

We report bla-harboring carbapenem-resistant Klebsiella pneumoniae in an emerging sequence type 307 lineage in a traveler returning from Puerto Rico to the Dominican Republic. Phylogenetic analyses indicate regional dissemination of this highly drug-resistant clone across the Americas, underscoring the need for adequate surveillance and infection control efforts to prevent further spread.
