Prevalence of Extended-Spectrum β-Lactamases Genes in Clinical Isolates of Pseudomonas aeruginosa
ABSTRACT Background and Objectives: Pseudomonas aeruginosa is an opportunistic pathogen resistant to various antibiotics. The aim of the present study was to study resistant patterns in clinical isolates of P. aeruginosa, classify them into pandrug resistance (PDR), extensive drug resistance (XDR) and multidrug resistance (MDR)...
متن کاملDetection of Ampc and Extended-Spectrum Beta-Lactamases in Clinical Isolates of Pseudomonas Aeruginosa from Patients with Cystic Fibrosis
ABSTRACT Background and Objectives: Pseudomonas aeruginosa is the most frequent opportunistic pathogen isolated from the sputum of patients with cystic fibrosis (CF). Resistance to β -lactam antibiotics may arise from over expression of the naturally occurring AmpC cephalosporinases or acquired extended-spectrum β-lactamases (ESBL). The aim of...
متن کاملExtended Spectrum Beta Lactamases Producing Pseudomonas aeruginosa Expressing Amp C Beta-Lactamase Enzyme
This study determined the presence of Amp C beta lactamase producing Pseudomonas aeruginosa among the seventy four uropathogens studied using standard techniques. Results obtained revealed that the studied isolates show an alarming rate of resistance to the extended spectrum beta lactam antibiotics and the penicillin derivatives tested. The combination of piperacillin and tazobactam was however...
متن کاملDetection of extended spectrum beta lactamases, ampc beta lactamases and metallobetalactamases in clinical isolates of ceftazidime resistant Pseudomonas Aeruginosa
We studied the prevalence of ceftazidime resistance in Pseudomonas aeruginosa and the rates of extended-spectrum β-lactamase (ESBL), AmpC β-lactamase (AmpC) and metallo-β-lactamase (MBL) production among the ceftazidime resistant Pseudomonas aeruginosa. A very high rate of MBL production was observed, which suggested it to be an important contributing factor for ceftazidime resistance among Pse...
متن کاملCo Existence of Ampc and Extended Spectrum Beta Lactamases Resistance in Metallo Beta Lactamases Producing Strains of Pseudomonas Aeruginosa
Pseudomonas aeruginosa is one of the commonest multi drug resistant bacteria causing nosocomial infection and Metallo-Beta-Lactamase production is one of the important reasons. The following study was conducted to determine incidence of MBL producing P.aeruginosa. and co existence of AmpC and ESBL production. Screening for MBL was done using imipenem disk and all the isolates found resistant we...
