Molecular Detection of Metallo-Beta Lactamases Among Carbapenem-Resistant Pseudomonas aeruginosa Isolated From Patients With Burn in Baghdad City, Iraq

Abstract

to examine the prevalence of MBL-producing Pseudomonas aeruginosa in burn and non-burn patients, 68 Pseudomonas aeruginosa isolates were collected from different clinical sources from two hospitals in Baghdad. Antibiotic susceptibility tests were PCR performed on carbapenem-resistant isolates, Among the Pseudomonas aeruginosa isolates, 50% were meropenem and 39% were imipenem, Among all Pseudomonas aeruginosa isolates, 63.23% were multidrug-resistant and 51.5% were resistant to carbapenems (meropenem and imipenem), It has been determined blaVIM, blaSPM and blaNDM in 22.9%, 2.9% and 5.7% respectively blaIMP were not observed. For the efficient treatment of carbapenem-resistant P. aeruginosa infections, epidemiological and geographic evaluation of MBL-producing P. aeruginosa should be taken into consideration.
