Plasmid-Mediated Quinolone Resistance Genes in Escherichia coli Strains Isolated from Healthy Dogs [PDF]

Veterinary Sciences
Knowledge about the potential roles of pets as reservoirs for plasmid-mediated quinolone resistance is still limited in Türkiye. Thus, in our study, the presence of plasmid-mediated quinolone genes (qnrA, qnrB and qnrS) was examined by multiplex ...

Quinolone resistance in Riemerella anatipestifer from Thai ducks: Mutation analysis of gyrA, parC, and plasmid-mediated quinolone resistance genes [PDF]

Veterinary World
Background and Aim: Riemerella anatipestifer is a Gram-negative bacterium causing systemic infections in ducks, often treated with quinolones. However, increasing resistance to quinolones poses a threat to effective treatment, and the molecular ...

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

Genetic Background and Expression of the New qepA4 Gene Variant Recovered in Clinical TEM-1- and CMY-2-Producing Escherichia coli [PDF]

, 2017
A new QepA4 variant was detected in an O86:H28 ST156-fimH38 Escherichia coli, showing a multidrug-resistance phenotype. PAβN inhibition ofqepA4-harboring transconjugant resulted in increase of nalidixic acid accumulation.

Clerocidin selectively modifies the gyrase-DNA gate to induce irreversible and reversible DNA damage [PDF]

, 2008
Clerocidin (CL), a microbial diterpenoid, reacts with DNA via its epoxide group and stimulates DNA cleavage by type II DNA topoisomerases. The molecular basis of CL action is poorly understood.

The phenazine pyocyanin is a terminal signalling factor in the quorum sensing network of Pseudomonas aeruginosa [PDF]

, 2006
Certain members of the fluorescent pseudomonads produce and secrete phenazines. These heterocyclic, redox-active compounds are toxic to competing organisms, and the cause of these antibiotic effects has been the focus of intense research efforts.

Shigella sonnei genome sequencing and phylogenetic analysis indicate recent global dissemination from Europe [PDF]

, 2012
Shigella are human-adapted Escherichia coli that have gained the ability to invade the human gut mucosa and cause dysentery1,2, spreading efficiently via low-dose fecal-oral transmission3,4. Historically, S.
