The emergence of Qnr-resistance among Klebsiella pneumoniae spp in Zahedan

, 2018
Although quinolone resistance results mostly from chromosomal mutations in Klebsiella pneumoniae, it may also be mediated by plasmid – encoded qnr determinants.

QNR/v-src^ts/ICN cells secrete and respond to mature TGF-β3.

, 2013
(A) Media were collected after a 30-hour incubation of QNR/v-srcts (v-srcts medium) and QNR/v-srcts/ICN (ICN medium) cells at 37°C or 41°C. QNR/v-srcts cells were incubated at 37°C in normal medium (BME) or conditioned media for 1 hour, before lysis ...

Plasmid-mediated quinolone resistance in expanded spectrum beta lactamase producing enterobacteriaceae in Morocco

Journal of Infection in Developing Countries, 2010
Introduction: Although independently acquired, plasmid-mediated quinolone resistance appears to be linked with extended-spectrum or AmpC-type beta-lactamases.

Wastewater‐Based Assessment of Antimicrobial Resistance and Bacterial Communities in Urban and Rural Areas in the Province of Trento (Italy)

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Wastewater from urban and rural areas was analyzed to investigate antimicrobial‐resistant bacteria and resistance genes. ESBL‐Escherichia coli and genes coding for clinically relevant resistances, namely, those to macrolides, carbapenems, and vancomycin, were higher in urban than in rural areas.
