Emergence of plasmid-mediated quinolone-resistant determinants in Klebsiella pneumoniae isolates from Tehran and Qazvin provinces, Iran [PDF]

, 2015
Background. Plasmid-mediated quinolone resistance is an increasing clinical concern, globally. The major objective of the present study was to identify the qnr-encoding genes among the quinolone non-susceptible K.

The Landscape of Salmonella enterica Serovar Gallinarum–Pullorum Antimicrobial Resistance in Bangladesh's Poultry Industry: A Combined Phenotypic and Molecular Study

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Salmonella enterica serovar Gallinarum–Pullorum isolated from chickens reveals a critical 89.13% prevalence of multidrug resistance. High phenotypic resistance to amoxicillin and tetracycline is genetically underpinned by a robust presence of resistance‐conferring genes (notably tetA, sul1, and blaCMY), highlighting a significant zoonotic threat to ...

Association of Transferable Quinolone Resistance Determinant qnrB19 with Extended-Spectrum β-Lactamases in Salmonella Give and Salmonella Heidelberg in Venezuela

International Journal of Microbiology, 2013
Four nontyphoidal Salmonella strains with resistance to extended-spectrum cephalosporins and nonclassical quinolone resistance phenotype were studied. Two S. Give were isolated from pediatric patients with acute gastroenteritis, and two S.

Genetic markers associated with resistance to beta-lactam and quinolone antimicrobials in non-typhoidal Salmonella isolates from humans and animals in central Ethiopia

Antimicrobial Resistance and Infection Control, 2017
Background Beta-lactam and quinolone antimicrobials are commonly used for treatment of infections caused by non-typhoidal Salmonella (NTS) and other pathogens. Resistance to these classes of antimicrobials has increased significantly in the recent years.
