Abstract

ABSTRACTNine carbapenem-resistantEnterobacteriaceaeisolates collected from eight patients in five German hospitals were investigated. Six isolates produced the OXA-48 carbapenemase, and three isolates produced OXA-162, which is a point mutant form of OXA-48. Both carbapenemase genes were located on IncL/M-type conjugative plasmids. Insertion sequence IS1999(truncated or not by IS1R) was located upstream of theblaOXA-48andblaOXA-162genes in all of the isolates. Pulsed-field gel electrophoresis typing indicated the clonal transmission of an OXA-48-producingKlebsiella pneumoniaestrain in two hospitals.
