ISEcp1-mediated transposition and homologous recombination can explain the context of bla(CTX-M-62) linked to qnrB2.

ABSTRACT: bla(CTX-M-62), a C508T variant of bla(CTX-M-3b), was transferred from Klebsiella pneumoniae JIE137 on a conjugative plasmid together with a class 1 integron containing the dfrA12-gcuF-aadA2 cassette array, ISCR1, and qnrB2. bla(CTX-M-62) lies between intact and rearranged copies of ISEcp1 in a configuration that can be explained by a combination of transposition and homologous recombination and which also illustrates the ability of ISEcp1 to mobilize an adjacent gene as part of transposition units of different sizes.
