Origin of Plasmid-Mediated Quinolone Resistance Determinant QnrA [PDF]
Antimicrobial Agents and Chemotherapy, 2005 ABSTRACT 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.

Interaction of the plasmid-encoded quinolone resistance protein QnrB19 with Salmonella Typhimurium DNA gyrase [PDF]
, 2020 Background: Plasmid-encoded quinolone resistance protein Qnr is an important factor in bacterial resistance to quinolones. Qnr interacts with DNA gyrase and reduces susceptibility to quinolones.

HOW DOES QUINOLONES ANTIBOTIC RESISTANCE DEVELOP? [PDF]
Bulletin of Pharmaceutical Sciences. Assiut University, 2020 The quinolone antibiotics arose in the early 1960s, with the first example having a narrow spectrum of activity with unfavourable pharmacokinetics. Over time, the development of new quinolone antibiotics has led to improved equivalents with an expanded ...

Extensive DNA mimicry by the ArdA anti-restriction protein and its role in the spread of antibiotic resistance [PDF]
, 2009 The ardA gene, found in many prokaryotes including important pathogenic species, allows associated mobile genetic elements to evade the ubiquitous Type I DNA restriction systems and thereby assist the spread of resistance genes in bacterial populations ...

Investigation of the Frequency of Plasmid-Dependent Quinolone Resistance Genes in Klebsiella Pneumoniae, Pseudomonas Aeruginosa and Escherichia Coli Isolated from Surgical Site Infections [PDF]
Armaghane Danesh Bimonthly Journal, 2022 Background & aim: In recent years, the rate of antibiotic resistance has been increasing which has led to the limitation of ways to control hospital infections (especially surgical site infections) and accurate treatment options.

PLASMID MEDIATED RESISTANCE TO QUINOLONES IN SALMONELLA
Archives of Veterinary Medicine, 2012 Plasmid mediated resistance to quinolones in Salmonella enterica is briefly presented. World wide spread of qnr determinants is evident, indicating the necessity for prudent use of antimicrobials in human and veterinary medicine. In discovering plasmid mediated resistance to quinolones antimicrobial resistance monitoring for β-lactam antibiotics is ...

Inhibition of R-plasmid transfer in Escherichia coli by 4-quinolones [PDF]
Antimicrobial Agents and Chemotherapy, 1987 Inhibition of transfer of four conjugative R plasmids by ciprofloxacin, enoxacin, norfloxacin, ofloxacin, and pipemidic acid was investigated in an Escherichia coli mating system. The absolute concentrations needed for inhibition of conjugation varied from 0.12 microgram/ml for ciprofloxacin to 16 micrograms/ml for pipemidic acid, but the relationship ...

Presence of plasmid-mediated quinolone resistance in klebsiella pneumoniae isolates possessing blaKPC in the United States [PDF]
, 2008 The presence of plasmid-mediated quinolone resistance genes [i.e., qnrA, qnrB, qnrS, aac(6')-Ib-cr, and qepA] was evaluated among 42 bla(KPC)-containing Klebsiella pneumoniae isolates collected in the eastern United States.
