چکیده
A combined-disk method using imipenem and cloxacillin was evaluated to discriminate between carbapenemase-producing (n = 56) and nonproducing (n = 62) strains of Pseudomonas aeruginosa. With a cloxacillin load of 4,000 μg/disk, this very simple method showed a sensitivity and a specificity of 100%, irrespective of the type of carbapenemase produced.

Evaluation of Carba NP Method for Rapid Detection of Pseudomonas aeruginosa Isolates Producing Carbapenemase Enzymes
Background and purpose: Recently, increased resistance to carbapenem antibiotics among Pseudomonas aeruginosa has raised concerns. The Carba NP test is used for detection of carbapenemase types. This study aimed at applying Carba NP method for rapid detection of P. aeruginosa isolates producing carbapenemase enzymes. Materials and methods: A total of 97 clinical specimens was collected from pa...
متن کاملComparative evaluation of two chromogenic tests for rapid detection of carbapenemase in Enterobacteriaceae and in Pseudomonas aeruginosa isolates.
We compared the performance of the Carba NP test and the Rosco Rapid CARB screen kit for detecting carbapenemase-producing Enterobacteriaceae and Pseudomonas aeruginosa. Both tests are rapid and highly sensitive; however, the Carba NP test showed superior specificity, and several uninterpretable results were observed with the Rapid CARB screen.
متن کاملDetection of KPC Carbapenemase in Pseudomonas aeruginosa Isolated From Clinical Samples Using Modified Hodge Test and Boronic Acid Phenotypic Methods and Their Comparison With the Polymerase Chain Reaction
BACKGROUND Bacterial resistance to antibiotics has become a major source of concern for public health. Pseudomonas aeruginosa strains are important opportunistic pathogens. These bacteria have a high resistance to a wide range of existing antimicrobials and antibiotics. OBJECTIVES The present study was performed to evaluate the frequency of KPC in P. aeruginosa isolated from clinical samples ...

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...
