Most of these were clinical isolates, but one was obtained from a hospital environment and one from pet turtles (Table 1). All of these isolates produced MBLs, with the majority of carbapenem-resistant P. rettgeri isolates producing IMP-type or NDM-type MBLs (Table 1). IMP-type MBLs were detected in isolates from Japan, Korea, and the United States, whereas NDM- type MBLs were detected in isolates worldwide. We obtained four clinical isolates of carbapenem- resistant P. rettgeri, which produced IMP-1, IMP-11 or IMP-70.
