BLASTn comparison of the blaOXA-244-containing Escherichia coli chromosomes. The K-12 (GenBank accession number NC_000913), F8111-1SC3 (GenBank accession number NZ_CP024269), and 266917_2 (GenBank accession number NZ_CP026723.1) strains were used as references. At the more external circle is shown the localization of the resistance genes and their putative genetic platforms of mobilization. The positions of the seven identical ISR1 and five IS1-family (89% of identity) sequences are also indicated. The strain positions on the figure are as follow (internal to external) (sequence type/serotype): K12 (ST10/O16:H48), F8111-1SC3 (ST182/O169:H41), 86J1 (ST361/O9:H30) MKGU01, 62D3 (ST1722/O1:H25) MKGY01, 85H4 (ST3541/O53:H18) MKGW01, 73G4 (ST3541/O53:H18) MKGV01, 266917_2 (ST38/O51:H30), 35J9 (ST38/O102:H6) MKGX01, 69E6 (ST38/O102:H6) MKGZ01, 78B5 (ST38/O102:H6) MKGT01, and 28Eco12 (ST38/O102:H6) NZ_CP038505.
