Carbapenem-resistant Pseudomonas aeruginosa in malaysia producing IMP-7 beta-lactamase.

چکیده
We have isolated and identified a carbapenem-resistant Pseudomonas aeruginosa strain from Malaysia that produces an IMP-7 metallo-beta-lactamase. This isolate showed high-level resistance to meropenem and imipenem, the MICs of which were 256 and 128 micro g/ml, respectively. Isoelectric focusing analyses revealed pI values of >9.0, 8.2, and 7.8, which indicated the possible presence of IMP and OXA. DNA sequencing confirmed the identity of the IMP-7 determinant.

Background and Objective: Pseudomonas aeruginosa is an opportunistic nosocomial pathogen. Evidence suggests that the incidence of enzyme-producing strains of Pseudomonas aeruginosa Metalo Beta Lactamases (MBL) is a major problem in the treatment of infections caused by this organism. The aim of this study was to investigate the frequency of class I and II integrons among metalobetalactamase pro...
متن کاملNosocomial outbreak of carbapenem-resistant Pseudomonas aeruginosa with a new bla(IMP) allele, bla(IMP-7).
Pseudomonas aeruginosa isolates from an outbreak in Canada were highly resistant to carbapenems and ceftazidime but not piperacillin. They produced a novel integron-associated metallo-beta-lactamase, designated IMP-7, with 91% identity to IMP-1. bla(IMP-7) was not detected with standard bla(IMP)-specific primers, owing to mismatches in the forward primer.
