pHN1122-1 carryingbla CTX-M-55 , from anEscherichia coli isolate from a dog, was completely sequenced. pHN1122-1 has an IncI2 replicon and typical IncI2-associated genetic modules, includingmok /hok-finO-yafA /B ,nikABC , and two transfer regions,tra andpil , as well as a shufflon.bla CTX-M-55 is found within a 3.084-kb ISEcp1 transposition unit that includes a fragment of IncA/C plasmid backbone. pHN1122-1 and closely related plasmids were identified in otherE. coli isolates from animals in China.
