Abstract Introduction: Infections caused by Pseudomonas aeruginosa are difficult to treat as
the majority of isolates exhibit varying degrees of beta-lactamase mediated resistance to …

AmpC are not routinely tested. Non-duplicate 245 isolates comprising 187 (76.3%) P.
aeruginosa and 58 (23.7%) P. mirabilis were tested for AmpC and ESBL production using …

Background Pseudomonas aeruginosa (P. aeruginosa) represents a great threat to public
health worldwide, due to its high ability to acquire resistance to different antibiotic classes …

Background: Widespread use and misuse of anti-infective agents have resulted in problems
of drug resistance linked to treatment of infectious diseases caused by worrisome pathogens …

Background There are various phenotypic methods for identifying class B and class A β-
lactamase enzymes in Pseudomonas aeruginosa. The purpose of this study was to compare …

Background: Pseudomonas aeruginosa is one of the most common causes of nosocomial
infections. Resistance of P. aeruginosa to β-lactam antibiotics may be the result of acquired …

Background: Resistance to broad-spectrum beta-lactams, mediated by extended-spectrum
beta-lactamases (ESBL), AmpC beta-lactamase, and metallo-beta-lactamase (MBL) …

This study was conducted to identify the β-lactamase content of 30 metallo-β-lactamase-
producing Pseudomonas aeruginosa isolated in 2007 from two Tunisian hospitals and to …

Methods: A total of 213 P. aeruginosa isolates were collected from two tertiary care centres
and tested against anti-pseudomonal antibiotics by antimicrobial susceptibility testing …

Extended-spectrum beta-lactamase production has been reported as one of the
mechanisms that contribute to acquired beta-lactam resistance in Pseudomonas …
