چکیده

Pseudomonas aeruginosa isolates (n=183), collected from bacteraemic patients hospitalised in Sao Paulo Hospital (Brazil) during 2000-2001, were screened for susceptibility to antimicrobial agents. The polymyxins were the most active compounds (100% susceptibility), followed by amikacin and cefepime (59.0%), meropenem (57.4%), and imipenem and gentamicin (55.2%). Imipenem-resistant isolates were ribotyped and screened for production of metallo-beta-lactamases (MBLs) by PCR with primers for bla(IMP), bla(VIM) and bla(SPM). MBL production was detected in 36 isolates (19.7% of the entire collection; 43.9% of the imipenem-resistant isolates) and the MBLs included SPM-1-like (55.6%), VIM-2-like (30.6%) and IMP-1-like (8.3%) enzymes.

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...

Background and Objective: Pseudomonas aeruginosa is a causative agent of nosocomial infections. Metallo-beta-lactamases (MBLs) are considered among the most crucial resistant agents of Pseudomonas aeruginosa to carbapenem. Because of the important role of carbapenemes in the treatment of Pseudomonas infections, in this study, the Pseudomonas aeruginosa producing metallo-beta-lactamases were inv...

Endemic Carbapenem-resistant Pseudomonas aeruginosa with Acquired Metallo-β-lactamase Determinants in European Hospital

Acquired metallo-beta-lactamases (MBLs) can confer broad-spectrum beta-lactam resistance (including carbapenems) not reversible by conventional beta-lactamase inhibitors and are emerging resistance determinants of remarkable clinical importance. In 2001, multidrug-resistant Pseudomonas aeruginosa carrying bla(VIM) MBL genes were found to be widespread (approximately 20% of all P. aeruginosa iso...
