Aztreonam/avibactam is a promising therapy against metallo-β-lactamase (MBL)-producing and other CRE, but emerging resistance threatens its effectiveness. Insertions in penicillin-binding protein 3 (PBP3), which are well described in Escherichia coli, are linked to reduced aztreonam/avibactam susceptibility but remain poorly characterized in Klebsiella pneumoniae. We report clinical K. pneumoniae carbapenemase-producing K. pneumoniae sequence type 11 isolates carrying a novel PBP3 YRIT insertion, conferring reduced susceptibility to aztreonam/avibactam and ceftazidime/avibactam. Functional and genetic studies suggest that the PBP3 insertion impairs β-lactam binding and, in combination with bla<sub>KPC-2</sub> and other β-lactamases, contributes to reduced susceptibility. Those findings demonstrate the emergence of a PBP3 insertion in a high-risk K. pneumoniae clone, underscoring the expansion of this resistance mechanism and the critical need for genomic surveillance and novel therapeutics to identify and treat such infections.</p>","PeriodicalId":11595,"journal":{"name":"Emerging Infectious Diseases","volume":"32 6","pages":""},"PeriodicalIF":6.6,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147856140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Median pairwise single-nucleotide polymorphism distances indicated lower intraclade relatedness for clades I (91), III (43), and IV (43), compared with clade II (1,455). Phylogenetic analysis showed regional clusters with varying predominant clades. Of 809 isolates that underwent antifungal susceptibility testing, 53 were echinocandin resistant, distributed across 3 clades; 92% (49/53) had FKS1 hotspot mutations, which varied regionally. Our findings corroborate ongoing transmission and clonal expansion of C. auris, likely propagated by multiple introductions within and between geographic regions. Echinocandin resistance in multiple clades highlights the need to increase awareness, improve treatment practices, and engage in rapid public health response.","PeriodicalId":11595,"journal":{"name":"Emerging Infectious Diseases","volume":"1 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147753292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
