Complete Nucleotide Sequence of <i>cfr</i> -Carrying IncX4 Plasmid pSD11 from Escherichia coli

Abstract

We report the complete nucleotide sequence of a plasmid carrying the multiresistance gene cfr. This plasmid was isolated from an Escherichia coli strain of swine origin in 2011. This 37,672-bp plasmid, pSD11, had an IncX4 backbone similar to those of the IncX4 plasmids obtained from the United States and Australia, in which the cfr gene was flanked by two copies of IS26 and a truncated Tn1331 was inserted.
