We characterized 29 bla CTX-M-27 -harboring plasmids of Escherichia coli sequence type 131 (ST131) sublineage C1/ H 30R isolates from healthy individuals and long-term-care facility (LTCF) residents. Most (27/29) plasmids were of the FIA, FIB, and FII multireplicon type with the same plasmid multilocus sequence typing (pMLST). Several plasmids (7/23) from LTCF residents harbored only bla CTX-M-27 as the resistance gene; however, their fundamental structures were very similar to those of previously isolated bla CTX-M-27 /F1:A2:B20 plasmids, suggesting their prevalence as a newly arising public health concern.
