An IncX3 epidemic plasmid carrying blaNDM-5 in Escherichia coli from swine in multiple geographic areas in China [PublishAheadOfPrint]

Six imported pigs originating from Guangdong, Henan, and Hunan provinces in China during October 2015-February 2017 were culture positive for meropenem-resistant Escherichia coli. The samples yielded 9 E. coli isolates of diverse sequence types carrying bla_NDM-5 on IncX3 (8 isolates from 5 farms) or IncFII (1 isolate from 1 farm) plasmids. The mcr-1 gene was co-harboured by four isolates. The IncX3 plasmids (~46 kb) carrying bla_NDM-5 were identical or nearly identical to each other.
