Two CMY-2 derivatives, CMY-31 (Gln215 →Arg) fromSalmonella enterica serotype Newport and CMY-36 (Ala77 →Cys and Gln193 →Glu) fromKlebsiella pneumoniae , were characterized. Both cephalosporinases functionally resembled CMY-2.bla CMY alleles occurred as parts of a putative transposon comprising ISEcp1B and aCitrobacter freundii -derived sequence carried by ColE1-like plasmids similar to CMY-5-encoding pTKH11 fromKlebsiella oxytoca .
