Class A and D Extended-Spectrum β-Lactamases in Imipenem Resistant Pseudomonas aeruginosa Isolated From Burn Patients in Iran.

Background: Pseudomonas aeruginosa remains a leading cause of severe wound infection and mortality in burn patients.

Objectives: The current study aimed to determine the prevalence of Ambler class A and D β-lactamases among P. aeruginosa isolated from infected burn injuries in Tehran, Iran.

Diversity of β-lactamases produced by imipenem resistant, Pseudomonas aeruginosa isolates from the bloodstream.

Introduction: The emergence of imipenem non-susceptible Pseudomonas aeruginosa isolates is a matter of great concern because these isolates can become resistant to all available antibiotics. This study conducted to characterize β-lactamase genes in imipenem resistant P. aeruginosa isolates from bloodstream.
