Abstract excerpt

Two CMY-2 derivatives, CMY-31 (Gln(215)-->Arg) from Salmonella enterica serotype Newport and CMY-36 (Ala(77)-->Cys and Gln(193)-->Glu) from Klebsiella pneumoniae, were characterized. Both cephalosporinases functionally resembled CMY-2. bla(CMY) alleles occurred as parts of a putative transposon comprising ISEcp1B and a Citrobacter freundii-derived sequence carried by ColE1-like plasmids similar to CMY-5-encoding...
