The current study was carried out to investigate the occurrence of multidrug resistant uropathogens among children under school age (six years old) in Soran city, North Iraq. A total number 200 urine samples were taken from six old suffering UTIs, attending Ashti hospital and Childbirth hospitals city July 2017 march 2018. High frequency UTIs less than two (34.3%) incidence significantly higher...

Of 19 environmental Escherichia coli (n = 12) and Klebsiella pneumoniae (n = 7) tested for quinolone resistance-related genes qnrA, qnrB, qnrC, qnrS and qepA, four each of E. coli and K. pneumoniae possessed qnrS, and another E. coli isolate possessed a new variant of qepA. This is the first detection of qepA in environmentally dwelling bacteria in Bangladesh.

Real-time PCR assays were developed for the enumeration of plasmid-mediated quinolone resistance (PMQR) determinants, such as the qnrA, qnrB, and qnrS genes, in different water samples and chicken feces. The results indicate that the developed assays are specific and sensitive for the quantification of qnr genes in complex samples.

Objective(s) Extensive use of quinolones has been associated with raising level of resistance. In the current, we focused on assessing the prevalence of Escherichia coli resistance to quinolones and frequency of qnrA, qnrB and qnrS in non ESBLs (extended spectrum beta-lactamases) and ESBLs producing E. coli with blaSHV and blaTEM. Materials and Methods One hundred and fifty E. coli isolates ...

A novel QnrB-like plasmid-mediated resistance determinant, QnrB19, was identified from an Escherichia coli clinical isolate from Colombia. Its gene was associated with an ISEcp1-like insertion element that did not act as a promoter for its expression. Using an in vitro model of transposition, we showed that the ISEcp1-like element was able to mobilize the qnrB19 gene.

The present study was conducted to investigate the prevalence of genes encoding resistance to aminoglycosides and fluoroquinolones among twenty-five Pseudomonas aeruginosa isolated between 2002 and 2009. In PCR, following genes were detected: ant(2″)-Ia in 9 (36.0%), aac(6')-Ib in 7 (28.0%), qnrB in 5 (20.0%), aph(3″)-Ib in 2 (8.0%) of isolates.
