Impacts of anthropogenic activity on the ecology of class 1 integrons and integron-associated genes in the environment [PDF]

The ISME Journal, 2011
Abstract The impact of human activity on the selection for antibiotic resistance in the environment is largely unknown, although considerable amounts of antibiotics are introduced through domestic wastewater and farm animal waste. Selection for resistance may occur by exposure to antibiotic residues or by co-selection for mobile genetic ...

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 ...

Iran's Escherichia coli AMR Landscape (2010–2025): A One Health Systematic Review and Meta‐Analysis

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
This One Health systematic review and meta‐analysis of 368 studies (2010–2025) reveals that 47.2% of E. coli isolates in Iran are ESBL‐producers, with alarming resistance to penicillins, cephalosporins, and fluoroquinolones. Critically, resistance to last‐resort antibiotics—colistin and ertapenem—is significantly increasing over time.

First Report of blaCTX‐M‐15 in a Marine Thermotolerant Enterobacter Isolate From Bangladesh: Genomic Insights Into Halotolerance and Antimicrobial Resistance

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Marine‐derived Enterobacter kobei, exhibiting thermotolerance and salt tolerance, is ESBL‐producing and harbors AMR genes (blaCTX‐M‐15, qnrS1) and mobile genetic elements, indicating environmental spread of antimicrobial resistance. ABSTRACT Marine ecosystems are becoming important reservoirs for antimicrobial resistance (AMR). However, genomic data on

Integrons in the Acid Mine Drainage Enironment

, 2022
Integrons are a two-part gene capture and expression system found in a wide diversity of bacterial lineages. The Integron is implicated in the spread and development of multiple-antibiotic resistance in clinical and animal production environments.

Metagenomic Characterisation of Antibiotic Resistance in Anaerobic Digesters and Their Implications for Environmental Health

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Anaerobic digester metagenomes revealed diverse resistance‐associated annotations and antibiotic target loci, highlighting their potential role in environmental AMR surveillance. The findings emphasise the need for cautious interpretation of resistome profiles and further host‐resolved analyses to determine the mobility and clinical relevance of ...

N‐(1H‐Indazolyl) Aryl Sulfonamide Hybrids as Potential Dihydropteroate Synthase Inhibitors: In Vitro Antibacterial Activity Against Escherichia coli and Staphylococcus aureus and Computational Modeling

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Sixteen indazole–sulfonamide hybrids exhibit species‐dependent antibacterial activity against E. coli and S. aureus, with the lead compound displaying an eightfold lower MIC than sulfathiazole against E. coli. Molecular docking against wild‐type and Sul1‐resistant dihydropteroate synthase identifies a candidate retaining binding affinity toward the ...
