Abstract Background and Aim: Class B beta-lactamases, termed metallo-beta-lactamases
(MBLs) such as VIM, IMP and SPM are an increasingly serious clinical problems. They have …

Background: Metallo-β-lactamase (MBL) producing Pseudomonas aeruginosa is
responsible for many important nosocomial outbreaks including pneumonia and septicemia …

Results: Out of 236 examined isolates, 122 isolates (51.4%) were resistant to imipenem. The
IMP-EDTA combination test showed that among 122 imipenem resistant strains, 110 strains …

Abstract Introduction: Imipenem-resistant Pseudomonas aeruginosa is an organism
expressing metallo-β-lactamase (MBL) enzyme, and is a serious agent of hospital infection …

Materials and Methods: In this cross-sectional study, 300 P. aeruginosa isolates were
collected from different clinical specimens in two provinces of Qazvin and Alborz hospitals …

Background: Pseudomonas aeruginosa is an opportunistic human pathogen that causes
serious problems, especially in people, who have immunodeficiency. In recent times …

Objectives: Unraveling mechanisms whereby Pseudomonas aeruginosa becomes resistant
to carbapenems through testing 114 non-duplicate P. aeruginosa clinical isolates for their …

Background: One of the major clinical problems regarding Pseudomonas aeruginosa is
attributed to metallo-beta-lactamases (MBL). This group of enzymes is a subset of beta …

Metallo-beta-lactamases (MBLs) are being reported with increasing frequency worldwide.
The aim of this study was to investigate the prevalence of blaIMP-1, blaVIM-1, 2 andblaSPM …

Materials and Methods: In this cross-sectional study, the antibiotic resistance profile of 122
clinical NFGNB isolates was determined by the Kirby-Bauer disk diffusion and microdilution …
