Widespread distribution of CTX-M and plasmid-mediated AmpC β-lactamases in Escherichia coli from Brazilian chicken meat

Memorias do Instituto Oswaldo Cruz, 2015
The dissemination of plasmid-mediated antimicrobial resistance genes may pose a substantial public health risk. In the present work, the occurrences ofblaCTX-M and plasmid-mediated ampCand qnrgenes were investigated in Escherichia colifrom 16 chicken ...

Frequency of Plasmid-Mediated Quinolone-Resistance (qnr) Genes in Pseudomonas aeruginosa Strains Isolated from Hospitalized Patients [PDF]

Journal of Mazandaran University of Medical Sciences
Background and purpose: Quinolones and fluoroquinolones are used to treat infection with resistant strains of Pseudomonas aeruginosa; however, the inappropriate use of antibiotics regardless of resistance patterns has led to the emergence of new and ...

New qnr Gene Cassettes Associated with Superintegron Repeats in Vibrio cholerae O1

Emerging Infectious Diseases, 2008
A novel qnr determinant emerged in ciprofloxacin-resistant Vibrio cholerae O1 from the Amazon region of Brazil. This qnrVC1 was in a typical class 1 integron. Its attC showed 89% identity with V. parahaemolyticus superintegron repeats. Analysis showed V.

EVALUATION OF PLASMID-MEDIATED QUINOLONE RESISTANCE ASSOCIATED WITH THE QNR GENES IN CLINICAL ISOLATES OF SHIGELLA SPP. IN BAGHDAD

The Iraqi Journal of Medical Sciences, 2016
Background:Although quinolone resistance results mostly from chromosomal mutations in Enterobacteriaceae, it may also be mediated by plasmid-encoded qnr determinants. Shigella harboring the novel qnr plasmid-mediated mechanism of quinolone resistance has

In vitro susceptibility to quinine and microsatellite variations of the Plasmodium falciparum Na⁺/H⁺ exchanger (Pfnhe-1) gene: the absence of association in clinical isolates from the Republic of Congo

Malaria Journal, 2011
Background Quinine is still recommended as an effective therapy for severe cases of Plasmodium falciparum malaria, but the parasite has developed resistance to the drug in some cases.

Presence of qnr gene in Escherichia coli and Klebsiella pneumoniae resistant to ciprofloxacin isolated from pediatric patients in China

BMC Infectious Diseases, 2008
Background Quinolone resistance in Enterobacteriaceae results mainly from mutations in type II DNA topoisomerase genes and/or changes in the expression of outer membrane and efflux pumps.
