A total of 49 consecutive nonduplicate Salmonella isolates collected in a nationwide survey performed in 2009 in Korea were included in this study. Resistance gene, sizes, and replicon sequence types (RSTs) of R plasmids, and sequence types (STs) and XbaI-macrorestriction patterns of extended-spectrum β-lactamase (ESBL)-producing isolates were determined. Six Salmonella enterica serovar Enteritidis isolates of ST11 showed ESBL phenotypes, and the isolates harbored an incompatibility group FII plasmid of RST S1:A-:B- carrying the bla(CTX-M-15) gene.
本研究纳入了 2009 年在韩国进行的全国性调查中收集的 49 株连续非重复的沙门氏菌分离株。本研究测定了 R 质粒的耐药基因、大小和复制子序列类型（RSTs），以及产超广谱β-内酰胺酶（ESBL）分离株的序列类型（STs）和 XbaI 大片段限制模式。6 株血清型为肠炎沙门氏菌 ST11 的分离株表现出 ESBL 表型，这些分离株携带携带 bla(CTX-M-15)基因的 RST S1:A-:B-型 FII 群不相容性质粒。
