Abstract

In this study, the progenitors of MCR-3, MCR-7 and MCR-5, namely NMCR-3, NMCR-4 and NMCR-5, were firstly discovered and indicating Aeromonas was a natural reservoir for MCR-3 and MCR-7. Furthermore, different evolutionary models for MCR-3, MCR-7 and MCR-5 were proposed.

摘要

在这项研究中,MCR-3、MCR-7 和 MCR-5 的前体,即 NMCR-3、NMCR-4 和 NMCR-5,首次被发现,表明气单胞菌是 MCR-3 和 MCR-7 的天然储库。此外,还提出了 MCR-3、MCR-7 和 MCR-5 的不同进化模型。
