Origin of plasmid-mediated quinolone resistance determinant QnrA.
Plasmid-mediated resistance to quinolones is increasingly reported in studies of Enterobacteriaceae. Using a PCR-based strategy, a series of gram-negative species were screened for qnrA-like genes. Shewanella algae, an environmental species from marine and fresh water, was identified as its reservoir. This is a one of the very few examples of progenitor identification of an acquired antibiotic ...
متن کاملHigh prevalence of the plasmid-mediated quinolone resistance determinant qnrA in multidrug-resistant Enterobacteriaceae from blood cultures in Liverpool, UK.
OBJECTIVES To determine the prevalence of the plasmid-mediated quinolone resistance qnrA gene in a selected collection of blood culture isolates of Enterobacteriaceae resistant to both ciprofloxacin and cefotaxime. METHODS Over a 29 month period, a total of 47 non-repetitive isolates of Enterobacteriaceae resistant to both ciprofloxacin and cefotaxime were identified. Isolates were screened f...
متن کاملEmergence of plasmid-mediated quinolone resistance genes in Enterobacteriaceae isolated from chickens in China.
increase in the number of different qnr-positive serotypes was observed in 2007, although the total number of positive isolates was evenly distributed between 2003 and 2007 (Table 1). The qnrS1 variant was highly prevalent in Salmonella Corvallis supporting the results recently published from Denmark, the Netherlands and the UK. 2,6,8 The Danish study included a restricted set of Salmonella Cor...
متن کاملPlasmid-mediated quinolone resistance in expanded spectrum beta lactamase producing enterobacteriaceae in Morocco.
INTRODUCTION Although independently acquired, plasmid-mediated quinolone resistance appears to be linked with extended-spectrum or AmpC-type beta-lactamases. Since no data are available in African countries, the prevalence of qnr genes at the University Hospital Ibn Rochd, Casablanca, Morocco, was investigated. METHODOLOGY Between October 2006 and March 2007, the following 39 randomly selecte...
متن کاملDetection of plasmid-mediated quinolone resistance determinants and qnrS expression in Enterobacteriaceae clinical isolates.
INTRODUCTION Rapid dissemination of plasmid-mediated quinolone resistance (PMQR) has been reported in clinical isolates. METHODOLOGY A total of 149 clinical isolates of Enterobacteriaceae were collected in Beijing and screened for PMQR genes using polymerase chain reaction (PCR). Real-time quantitative PCR was used to study the expression of qnrS. RESULTS The rates of qnr and aac(6')-Ib-cr ...
