Abstract
Escherichia coli bacteria with extended-spectrum β-lactamase (ESBL) type CTX-M resistance were isolated from water samples collected close to research stations in Antarctica. The isolates had bla(CTX-M-1) and bla(CTX-M-15) genotypes and sequence types (ST) indicative of a human-associated origin. This is the first record of ESBL-producing enterobacteria from Antarctica.
摘要
从靠近南极洲研究站采集的水样中分离出具有 CTX-M 型扩展谱β-内酰胺酶（ESBL）耐药性的大肠杆菌。这些分离株具有 bla(CTX-M-1)和 bla(CTX-M-15)基因型和序列型（ST），表明其来源于人类。这是南极洲产 ESBL 肠杆菌的首次记录。
