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.

Molecular Detection of Class 1 Integrons in Burkholderia pseudomallei

Проблемы особо опасных инфекций, 2011
PCR with primers specific to flanking sequences of gene cassette insertion region and 3'-conservative segment of integrons was used for class 1 integron detection in Burkholderia pseudomallei, B. mallei and B. thailandensis.

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.

Widespread dissemination of class 1 integron components in soils and related ecosystems as revealed by cultivation-independent analysis

Frontiers in Microbiology, 2014
Class 1 integrons contribute to the emerging problem of antibiotic resistance in human medicine by acquisition, exchange, and expression of resistance genes embedded within gene cassettes.

Temporal dynamics of class 1 and class 3 integron pools in treated wastewater

Water Research
Wastewater is a hotspot for the spread and evolution of antimicrobial resistance (AMR), with integrons playing a key role in the dissemination of AMR. However, there is limited information available regarding the integron pool of wastewater environments.

Antimicrobial Resistance, Class 1 Integrons, and Genomic Island 1 in Salmonella Isolates from Vietnam

PLoS ONE, 2010
The objective was to investigate the phenotypic and genotypic resistance and the horizontal transfer of resistance determinants from Salmonella isolates from humans and animals in Vietnam.The susceptibility of 297 epidemiologically unrelated non-typhoid Salmonella isolates was investigated by disk diffusion assay.

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).
