Antimicrobial Effect of Spices and Their Phytochemicals: A Novel Approach to Overcoming Antibiotic Resistance

MedComm, Volume 7, Issue 4, April 2026.
This graphical abstract shows the antibacterial potential of phytochemicals from 15 spices, showcasing key compounds, their extraction methods, and mechanisms of action. It highlights membrane disruption, ROS generation, enzyme inhibition, and biofilm prevention as core antibacterial pathways.

Association of phylogenetic distribution and presence of integrons with multidrug resistance in Escherichia coli clinical isolates from children with diarrhoea

Journal of Infection and Public Health, 2020
Background: Escherichia coli strains include both commensal and virulent clones distributed in different phylogenetic groups. Antimicrobial resistance is an increasingly serious public health threat at the global level and integrons are important mobile ...

Replicative resolution of integron cassette insertion [PDF]

Nucleic Acids Research, 2012
Site-specific recombination catalyzed by tyrosine recombinases follows a common pathway consisting of two consecutive strand exchanges. The first strand exchange generates a Holliday junction (HJ), which is resolved by a second strand exchange. In integrons, attC sites recombine as folded single-stranded substrates.

Mechanism and Molecular Design Principles of Cationic Surfactants: From Charge‐Driven Membrane Interactions to Next‐Generation Quaternary Ammonium Compounds

ChemMedChem, Volume 21, Issue 5, 13 March 2026.
Within this review we provide an overview of the social relevance of quaternary ammonium surfactants, different classes of these agents, their interaction mechanism with cellular membranes, structure activity relation, bacterial resistance toward these systems and new approaches to guarantee their long‐term efficiency.

The Integron: Adaptation On Demand

Microbiology Spectrum, 2015
ABSTRACT The integron is a powerful system which, by capturing, stockpiling, and rearranging new functions carried by gene encoding cassettes, confers upon bacteria a rapid adaptation capability in changing environments. Chromosomally located integrons (CI) have been identified in a large number of environmental Gram-negative ...

Integron-Associated Antibiotic Resistance in Salmonella typhi.

Archives of Razi Institute, 2021
Salmonella enteric serovar Typhi (S. typhi) and paratyphi (S. paratyphi) bacteria exclusively found in humans, cause typhoid fever, an acute, and possibly deadly systemic infection. Typhoid fever is caused by a species of rod-shaped, Gram-negative Enterobacteriaceae called S. typhi.

Rapid reconstruction of multidrug‐resistant bacterial genomes using CycloneSEQ nanopore sequencing

iMetaOmics, Volume 3, Issue 1, March 2026.
Multidrug‐resistant (MDR) bacteria commonly harbor highly complex genomes enriched with mobile elements and resistance islands, which are challenging to resolve using short‐read sequencing. Here, we evaluated CycloneSEQ, a newly developed Chinese nanopore sequencing platform, for MDR genome reconstruction.

Multidrug-resistant Salmonella enterica serovar Panama carrying class 1 integrons is invasive in Taiwanese children

Journal of the Formosan Medical Association, 2013
An increase in group D Salmonella isolates with high antimicrobial resistant rates is being seen in Taiwan. This study aimed to determine the multidrug-resistant (MDR, more than three antibiotics) phenotype, genotype, and the correlation between the ...

Integrons inSalmonellaKeurmassar, Senegal

Emerging Infectious Diseases, 2004
To the Editor: Infections caused by Salmonella are the primary cause of foodborne diseases; multidrug resistance to Salmonella enterica subsp. enterica is increasing. The selective pressure created by the widespread use of antimicrobial agents in animals and humans as prophylactic and therapeutic agents may have contributed to the dissemination of ...
