To describe a clinical case of sequence type (ST) 32 harbouring a New Delhi metallo-β-lactamase (NDM) in Ecuador.
We used multilocus sequence typing (MLST) to confirm the bacterial species and the sequence type of an isolate. We used synergy with the imipenem-EDTA disc method and the carbapenem inactivation method (CIM) to determine carbapenemase production; the presence of a carbapenemase gene was confirmed by PCR amplification and amplicon sequencing.
Molecular characterization revealed the presence of . ST32 harbouring the gene in Ecuador. The gene was isolated through PCR and amplified from a purified plasmid.
To the best of our knowledge, this is the first report of . ST32 harbouring the gene.
描述在厄瓜多尔发现的携带新德里金属β-内酰胺酶(NDM)的序列类型(ST)32的临床病例。
我们使用多位点序列分型(MLST)来确认分离株的细菌种类和序列类型。我们采用亚胺培南-EDTA纸片协同法和碳青霉烯酶灭活法(CIM)来确定碳青霉烯酶的产生;通过PCR扩增和扩增子测序确认碳青霉烯酶基因的存在。
分子特征显示在厄瓜多尔存在携带该基因的ST32。该基因通过PCR从纯化质粒中分离并扩增得到。
据我们所知,这是首次报道携带该基因的ST32。
