Frequency of PER, VEB, SHV, TEM and CTX-M Genes in Resistant Strains of Pseudomonas aeruginosa Producing Extended Spectrum β-Lactamases
BACKGROUND Pseudomonas aeruginosa is the most common pathogen causing nosocomial infections. Resistance of P. aeruginosa strains to broad-spectrum cephalosporins may be mediated by extended-spectrum β-lactamases (ESBLs). OBJECTIVES We intended to investigate the prevalence of ESBLs and antimicrobial susceptibilities of P. aeruginosa isolated from patients in Zahedan, Iran. MATERIALS AND MET...
متن کاملfrequency of per, veb, shv, tem and ctx-m genes in resistant strains of pseudomonas aeruginosa producing extended spectrum β-lactamases
conclusions according to our results, blatem-116 was the most frequent isolated esbl gene among the p. aeruginosa strains isolated from patients. results ciprofloxacin and piperacillin were the most efficient antipseudomonal agents. the results disclosed that 19 (16.37%) of the isolates were multidrug resistant and 8 (6.89%) were esbl-positive. of the 116 isolates, 30 (25.86%) were resistant to...
متن کاملPrevalence 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 TEM, SHV and PER Type Extended-Spectrum ß-Lactamase Genes among Clinical Strains of Pseudomonas aeruginosa Isolated from Burnt Patients at Shafa-Hospital, Kerman, Iran
Objective(s) This study was carried out to evaluate the existence of the TEM, SHV and PER ESBL genes in ESBL producing strains of Pseudomonas aeruginosa isolated from burnt patients at Shafa-hospital, Kerman, Iran. Materials and Methods A total of 120 strains of P. aeruginosa were isolated from 245 patients in burn unit of Shafa-hospital during January 2006 to December 2007. MIC of antibioti...
متن کاملStudy of Antibiotic Susceptibility Pattern and Frequency of Extended Spectrum β-lactamases Genes TEM and SHV in Urinary Tract Isolates of Escherichia coli and Klebsiella pneumoniae in Tabriz
Background & objectives: Urinary tract infection (UTI) is one of the most common types of human infections and Escherichia coli and Klebsiella pneumonia are the main causes of urinary tract infection among the gram negative bacteria. The prevalence of extended-spectrum β-lactamases (ESBLs) among these bacteria and hence resistant strains to β-lactam antibiotics have increased in recent decades...
