qnr prevalence in ceftazidime-resistant Enterobacteriaceae isolates from the United States.

چکیده
We screened 313 ceftazidime-resistant Enterobacteriaceae isolates obtained in the United States from 1999 to 2004 for all three known qnr genes. A qnr gene was present in 20% of Klebsiella pneumoniae isolates, 31% of Enterobacter sp. isolates, and 4% of Escherichia coli isolates. qnrA and qnrB occurred with equivalent frequencies and, except for qnrB in enterobacters, were stable over time. qnrS was absent.

Prevalence of qnr Genes in Extended-Spectrum β-Lactamase Producing Klebsiella pneumoniae Isolated from Clinical Urine Specimens in University Teaching Hospitals, Iran
Background and Aims: Extended-spectrum β-lactamase (ESBL) producing gram negative bacteria are resistant to penicillins, narrow and extended-spectrum cephalosporins, and aztreonam; also they are frequently resistant to trimethoprim-sulfamethoxazole, aminoglycosides, and quinolones. This study aimed to investigate the prevalence of plasmid-mediated quinolone resistance (PMQR) determinants q...

OBJECTIVE Quinolone resistance is usually caused by various chromosomal mutations, but has been more recently associated with plasmids which carry the qnr determinant. The aim of this study is to investigate the prevalence of qnr genes in clinical isolates of Enterobacteriaceae in Jamaica. METHODS A total of 255 non-duplicate fluoroquinolone-resistant Enterobacteriaceae clinical isolates, com...

Background and Aim: Infection by drug resistant Pseudomonas aeruginosa causes important therapeutic problems. The present study was performed to investigate the antibiotic susceptibility and prevalence of antimicrobial resistance genes in P. aeruginosa. Materials and Methods: In this cross sectional study, 61 clinical P. aeruginosa isolates were collected in Sanandaj between April and September...
متن کاملBroader distribution of plasmid-mediated quinolone resistance in the United States.
The plasmid-encoded quinolone resistance gene qnrA confers low-level quinolone resistance, facilitating selection of higher-level resistance. Epidemiologic surveys for qnrA were extended to isolates of Enterobacter spp. and to quinolone-susceptible Enterobacteriaceae. Two (10%) of 20 ceftazidime-resistant quinolone-susceptible Klebsiella pneumoniae strains carried the gene, as did 12 (17%) of 7...
