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 …

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 …

Acinetobacter baumannii and Pseudomonas aeruginosa are non-fermentative Gram-
negative bacilli with the ability to produce β-lactamase, they are often resistant to β-lactam …

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

Background The increased prevalence of carbapenem-resistant Gram-negative isolates
caused by Metallo-β-lactamase (MBL) is worrisome in clinical settings worldwide. The …

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 …

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

Background Pseudomonas aeruginosa is considered as one of the most emerging threats in
this century. Serious infections caused by this pathogen are often treated by carbapenems …

Introduction: The emergence and rapid spread of bla IMP and bla VIM metallo-beta-
lactamase (MBL) producing Gram-negative bacteria causing nosocomial infections are of …
