Identification and Characterization of Metallo-β-Lactamases Producing Pseudomonas aeruginosa Clinical Isolates in University Hospital from Zanjan Province, Iran
Background: Infectious by Pseudomonas aeruginosa has spread worldwide and metallo-beta-lactamases (MBL) are being reported with increasing frequency. The aim of this study was to investigate the antibiotic susceptibility and distribution of blaVIM and blaIMP genes in P. aeruginosa isolates from Zanjan Province of Iran. Methods: A total of 70 P. aeruginosa isolates were identified from patients ...
متن کاملFrequency of extended spectrum beta lactamase producer P. aeruginosa strains isolated from burned patients of Motahari hospital, Teharan, Iran
Pseudomonas aeruginosa is an opportunistic pathogen which is naturally resistant to a large range of antibiotics like lots of Beta–Lactams (penicillins, cephalosporins and carbapenems) and may cause additional resistance after unsuccessful treatment. The understanding of beta-lactamase identification and detection in these bacteria is very valuable. In recent years a number of variety of new be...
متن کاملEvaluation of different methods for detection of metallo-beta-lactamases in Pseudomonas aeruginosa clinical isolates.
Metallo-beta-lactamases (MBLs) produced by Pseudomnonas aeruginosa are a serious threat due to their ability to be transmitted between the same as well as different bacterial species. Different methods are applied in the clinical laboratory to detect MBLs. The aim of this study was to compare 4 phenotypic methods and a PCR assay for their ability to detect MBLs in clinical isolates of carbapene...

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...
متن کاملHidden VIM-1 metallo-beta-lactamase phenotypes among Acinetobacter baumannii clinical isolates.
A total of 87 Acinetobacter baumannii nonrepetitive consecutive clinical isolates were tested for the presence of metallo-beta-lactamases (MBLs). Results of phenotypic assays (MBL Etest, imipenem/imipenem-EDTA combined-disk test, and imipenem/EDTA double-disk synergy test) were negative in all cases, but molecular testing revealed the presence of two bla(VIM-1)-carrying isolates. One isolate ha...
