We report the first OXA-181-producing strain in China. blaOXA-181 was found in sequence type 410 (ST410) Escherichia coli strain WCHEC14828 from a Chinese patient without recent travel history. Genome sequencing and conjugation experiments were performed. blaOXA-181 was carried on a 51-kb self-transmissible IncX3 plasmid and was linked with qnrS1, a quinolone resistance gene. blaOXA-181 was introduced onto the IncX3 plasmid from a ColE2-type plasmid, and IncX3 plasmids have the potential to mediate the dissemination of blaOXA-181.
我们报告了中国首例产 OXA-181 菌株。blaOXA-181 存在于一位无近期旅行史的中国患者携带的序列型 410(ST410)大肠埃希菌 WCHEC14828 中。进行了基因组测序和接合实验。blaOXA-181 位于一个 51kb 的可自我传播的 IncX3 质粒上,与喹诺酮类耐药基因 qnrS1 相连。blaOXA-181 由 ColE2 型质粒引入 IncX3 质粒,而 IncX3 质粒有可能介导 blaOXA-181 的传播。
