Development of a TaqMan multiplex PCR assay for detection of plasmid-mediated ampC β-lactamase genes.
A multiplex, real-time TaqMan assay was designed to identify clinical isolates carrying plasmid-mediated ampC genes. The specificity and sensitivity of this assay were 100% when testing characterized AmpC/non-AmpC-producing isolates and randomly selected clinical isolates. This is a rapid assay that can be performed in a clinical microbiology laboratory.
متن کاملDetection of plasmid-mediated AmpC beta-lactamase genes in clinical isolates by using multiplex PCR.
Therapeutic options for infections caused by gram-negative organisms expressing plasmid-mediated AmpC beta-lactamases are limited because these organisms are usually resistant to all the beta-lactam antibiotics, except for cefepime, cefpirome, and the carbapenems. These organisms are a major concern in nosocomial infections and should therefore be monitored in surveillance studies. Six families...
متن کاملDetection of plasmid-mediated qnr genes among the quinolone-resistant Escherichia coli isolates in Iran.
INTRODUCTION Plasmid-mediated quinolone resistance, which complicates treatment, has been increasingly identified in Escherichia coli isolates worldwide. The purpose of this study was to identify the plasmid-mediated qnrA and qnrB genes among the quinolone-resistant Escherichia coli isolated from urinary tract infections in Iran. METHODOLOGY A total of 140 Escherichia coli isolates were colle...

Multiplex PCR for detection of three plasmid-borne genes of enteroaggregative Escherichia coli strains.
We developed a novel multiplex PCR assay for enteroaggregative Escherichia coli (EAEC) detection, by using three plasmid-borne genes (the aggregative adherence [AA] probe, aap, and aggR). One or more of the loci were detected in 24 (86%) of 28 patient isolates analyzed. The multiplex PCR assay is a fast, convenient, and sensitive molecular test to detect EAEC.
