Characterization of the variable region in the class 1 integron of antimicrobial-resistant Escherichia coli isolated from surface water

Brazilian Journal of Microbiology, 2016
Fecal bacteria are considered to be a potential reservoir of antimicrobial resistance genes in the aquatic environment and could horizontally transfer these genes to autochthonous bacteria when carried on transferable and/or mobile genetic elements. Such

The European Union Summary Report on Antimicrobial Resistance in zoonotic and indicator bacteria from humans, animals and food in 2023–2024

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract This report presents the main findings of the 2023–2024 harmonised antimicrobial resistance (AMR) monitoring in Salmonella spp., Campylobacter jejuni and Campylobacter coli from humans, food‐producing animals (broilers, laying hens, fattening turkeys, fattening pigs and bovines under 1 year of age), and derived meat.

Integron Prevalence and Diversity in Manured Soil [PDF]

Applied and Environmental Microbiology, 2011
ABSTRACT The levels of integron abundance and diversity in soil amended with pig slurry were studied. Real-time PCR illustrated a significant increase in class 1 integron prevalence after slurry application, with increased prevalence still evident at 10 months after application.

An evaluation of clonal relationship by PFGE method in Acinetobacter baumannii isolates, examining integron presence and antibiotic resistance

Journal of Infection in Developing Countries
Introduction: This study aims to investigate the presence of class 1, 2, and 3 integrons in Acinetobacter baumannii isolates, evaluate the relationship between integrons and antibiotic resistance and determine the clonal relationship between isolates by

Efficiency of integron cassette insertion in correct orientation is ensured by the interplay of the three unpaired features of attC recombination sites

Nucleic Acids Research, 2016
The integron is a bacterial recombination system that allows acquisition, stockpiling and expression of cassettes carrying protein-coding sequences, and is responsible for the emergence and rise of multiresistance in Gram-negative bacteria.

Divergent Evolution and Local Establishment of Multidrug‐Resistant Shigella sonnei in China

MedComm, Volume 7, Issue 1, January 2026.
• Evolutionary history and local establishment of Chinese Shigella sonnei are unclear. • Chinese S. sonnei developed into four clades and ONPG‐negative variants. • The antimicrobial resistance phenotype of Clade I was due to an IncB/O/K/Z plasmid. • Antimicrobial resistance of Clade II was due to IncFII and IncB/O/K/Z plasmids.

IntI2 Integron Integrase in Tn7 [PDF]

Journal of Bacteriology, 2002
ABSTRACTIntegrons can insert and excise antibiotic resistance genes on plasmids in bacteria by site-specific recombination. Class 1 integrons code for an integrase, IntI1 (337 amino acids in length), and are generally borne on elements derived from Tn5090, such as that found in the central part of Tn21. A second class of integron is found on transposon

Antibiotic Resistance Genes in Klebsiella pneumoniae and Heavy Metal Contamination in Tilapia (Oreochromis niloticus): A Public Health Risk Assessment in Bangladesh

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Species‐specific 16S‐23S ITS and antibiotic resistance IntI, blaCTX‐M, blaTEM and blaSHV genes of Klebsiella pneumoniae were detected, and most of the isolates were multidrug‐resistant. Target hazard quotient values of Fe for >1 revealed a higher level of hazard index. Target cancer risk values of Fe exceeded the recommended value (<10−4).

Molecular Characterization of Integrons in Acinetobacter baumannii : Description of a Hybrid Class 2 Integron [PDF]

Antimicrobial Agents and Chemotherapy, 2000
ABSTRACT Twenty Acinetobacter baumannii strains resistant to various antibiotics were analyzed for integron content and sequences of the amplification products. Sixteen clinical isolates had a class 1 integron, 2 contained an additional class 1 or class 2 integron, but no class 3 integron was detected ...

A Novel Integron in the Genome of Escherichia Coli Isolated From Indonesian Monitor Lizard (Varanus Spp). [PDF]

, 2001
The genotype of antibiotic resistance in natural isolates of Escherichia coli was determined through integron detection and characterization of the associated antibiotic resistance. E.
