Draft genome sequences of colistin-resistant MCR-1-producing Escherichia coli ST1850 and ST74 strains isolated from commercial chicken meat

We present here the draft genome sequences of two colistin-resistant mcr-1 -carrying Escherichia coli strains belonging to sequence type 74 (ST74) and ST1850, isolated from commercial chicken meat in Brazil. Assembly of this draft genome resulted in 5,022,083 and 4,950,681 bp, respectively, revealing the presence of the IncX4 plasmid-mediated mcr-1 gene responsible for resistance to colistin.
