On‐site pilot‐scale advanced oxidation pretreatment of hospital wastewater: assessment of pharmaceuticals, pathogens, antibiotic resistance genes and acute ecotoxicity

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1478-1491, August 2026.
Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.

One Health Insights From Pteropus medius: Nipah Virus Spillover, Microbiota, and Antimicrobial Resistance

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Environmental and anthropogenic drivers of antibiotic resistance dissemination. The cycle reinforces how anthropogenic inputs, such as sewage, animal dung, hospital effluent, and agricultural runoff bring resistant bacteria and antibiotic residues into soil and water.

Recent Advances in the Molecular Mechanisms of Bacterial Anti‐Phage Defence Systems

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
Panoptes as an example for an antiphage system consists of OptS producing a cyclic dinucleotide that prevents activation of OptE, a transmembrane protein. Phage T4 infection introduces the sponge protein Acb2 that adsorbs the cyclic dinucleotide thus activating OptE which disrupts the cell membrane aborting phage infection.

Evidence for dynamic exchange of qac gene cassettes between class 1 integrons and other integrons in freshwater biofilms

, 2009
Class 1 integrons carried by pathogens have acquired over 100 different gene cassettes encoding resistance to antimicrobial compounds, helping to generate a crisis in the management of infectious disease.

Occurrence and Distribution of Environmental Pseudomonas aeruginosa From Hospitals in Bangladesh Reveals Diverse Strain Families, Multidrug Resistance, and Biofilm Formation

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Environmental reservoirs in Bangladeshi hospitals harbor phylogenetically diverse, multidrug‐resistant Pseudomonas aeruginosa with extensive biofilm‐forming capacity and class 1 integron‐associated resistance genes. These findings highlight hospital environments as persistent sources of antimicrobial resistance dissemination and underscore the need for

Eco‐Geography Reverses Dominant AMR Reservoirs in Klebsiella pneumoniae: Integron‐Rich Mobilomes and Cross‐Niche Connectivity

Advanced Science, Volume 13, Issue 42, 28 July 2026.
Dominant antimicrobial resistance reservoirs in Klebsiella pneumoniae vary across eco‐geographic settings rather than following a universal pattern. Integrated One Health and global genomic analyses show that lineage structure, integron load, and cross‐niche connectivity shape whether AMR burden accumulates primarily in human or nonhuman compartments ...

Detection of Class 1 and 2 Integrons, β-Lactamase Genes and Molecular Characterization of Sulfonamide Resistance in Escherichia coli Isolates Recovered from Poultry in China [PDF]

Pakistan Veterinary Journal, 2013
This study aimed to detect integrons, β-lactamase genes and to characterize sulfonamide resistant E. coli isolates recovered from poultry. All the isolates (n=38) were investigated for the presence of integrons, Sul1, Sul2, Sul3 genes by PCR. Class 1 and
