摘要
我们在此报道一种携带mcr-1基因的新型质粒，pMCR-1-P3质粒携带在从中国养猪场分离的大肠埃希氏菌菌株中。 pMCR-1-P3属于IncY不相容组，并且是含有大部分噬菌体相关序列的噬菌体样质粒。 该质粒的骨架不同于先前报道的其他携带mcr-1的质粒的骨架。
We report here a new type of plasmid that carries the mcr-1 gene, the pMCR-1-P3 plasmid, harbored in an Escherichia coli strain isolated from a pig farm in China. pMCR-1-P3 belongs to the IncY incompatibility group and is a phage-like plasmid that contains a large portion of phage-related sequences. The backbone of this plasmid is different from that of other mcr-1-carrying plasmids reported previously.
