Molecular Characterization of Carbapenemase-Producing Pseudomonas aeruginosa of Czech Origin and Evidence for Clonal Spread of Extensively Resistant Sequence Type 357 Expressing IMP-7 Metallo-β-Lactamase.

ABSTRACT: The objective of this study was to perform molecular surveillance for assessing the spread of carbapenemase-producing Pseudomonas aeruginosa in Czech hospitals. One hundred thirty-six carbapenemase-producing isolates were recovered from 22 hospitals located throughout the country. Sequence type 357 (ST357) dominated (n = 120) among carbapenemase producers. One hundred seventeen isolates produced IMP-type (IMP-7 [n = 116] and IMP-1 [n = 1]) metallo-β-lactamases (MβLs), 15 produced the VIM-2 MβL, and the remaining isolates expressed the GES-5 enzyme. The bla_IMP-like genes were located in three main integron types, with In-p110-like being the most prevalent (n = 115). The two other IMP-encoding integrons (In1392 and In1393) have not been de
