Abstract We screened ten CTX-M-55-producing Shigella and Salmonella isolates from a national surveillance in Korea. The blaCTX-M-55 was located on the IncI1 (n = 5), IncA/C (n = 4) and IncZ (n = 1) plasmids, downstream of IS Ecp1 , IS 26 -IS Ecp1 and IS Ecp1 -IS 5 sequences, respectively. These resu...
