Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

open access: yesAnimal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...

Mutational Diversity in the Quinolone Resistance-Determining Regions of Type-II Topoisomerases of Salmonella Serovars

open access: yesAntibiotics, 2021
Quinolone resistance in bacterial pathogens has primarily been associated with mutations in the quinolone resistance-determining regions (QRDRs) of bacterial type-II topoisomerases, which are DNA gyrase and topoisomerase IV. Depending on the position and

Detection of plasmid-mediated quinolone resistance genes in clinical isolates of Enterobacter spp. in Spain [PDF]

open access: yes, 2009
We have studied by PCR and DNA sequencing the presence of the qnrA, qnrB, qnrS, aac(6′)-Ib-cr, qepA, intI1, and ISCR1 genes in 200 clinical isolates of Enterobacter cloacae (n = 153) and E.

Genomic Insights Into Spatiotemporal Dynamics of Acquired Azithromycin Resistance Genes in Salmonella Strains Worldwide

open access: yesFood Safety and Health, EarlyView.
ABSTRACT Azithromycin has been used for clinical invasive infections caused by fluoroquinolone‐ and third‐generation cephalosporin‐resistant Salmonella, and mass drug administration with azithromycin has been used to reduce under‐5 mortality in children in some countries.

Broader Distribution of Plasmid-Mediated Quinolone Resistance in the United States [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 2005
ABSTRACT The plasmid-encoded quinolone resistance gene qnrA confers low-level quinolone resistance, facilitating selection of higher-level resistance. Epidemiologic surveys for qnrA were extended to isolates of Enterobacter spp. and to quinolone-susceptible

Potent monoclonal antibodies against multidrug‐resistant hypervirulent Klebsiella pneumoniae

open access: yesInterdisciplinary Medicine, EarlyView.
A novel immunization strategy using a low‐virulence, multidrug‐resistant strain yields synergistic monoclonal antibodies against hypervirulent Klebsiella pneumoniae. These antibodies provide cross‐serotype protection through a dual‐mechanism of pathogen clearance and immunomodulation, offering a promising non‐antibiotic therapeutic for resistant ...

Phenotypic and Genotypic Characterization of Multidrug-Resistant Enterobacter hormaechei Carrying qnrS Gene Isolated from Chicken Feed in China

open access: yesMicrobiology Spectrum, 2022
Multidrug resistance (MDR) in Enterobacteriaceae including resistance to quinolones is rising worldwide. The plasmid-mediated quinolone resistance (PMQR) gene qnrS is prevalent in Enterobacteriaceae. However, the qnrS gene is rarely found in Enterobacter

qnrB , Another Plasmid-Mediated Gene for Quinolone Resistance [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 2006
ABSTRACT A novel plasmid-mediated quinolone resistance gene, qnrB , has been discovered in a plasmid encoding the CTX-M-15 β-lactamase from a Klebsiella pneumoniae strain isolated in South India. It has less than 40% amino acid identity with the original qnr (

Assessment of a phenotypic algorithm to detect plasmid-mediated quinolone resistance in Enterobacteriaceae

open access: yes, 2016
Quinolone resistance in Gram-negative bacteria is the result of mutations in the quinolone resistance-determining region (QRDR) in chromosomally located genes encoding type II topoisomerases and, to a lesser extent, altered permeability. Plasmid-mediated

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

open access: yesPolymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...
