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.

Adaptation and validation of a quantitative vanA/vanB DNA screening assay on a high-throughput PCR system

Scientific Reports
Vancomycin resistant enterococci (VRE) are a leading cause of ICU-acquired bloodstream infections in Europe. The bacterial load in enteral colonization may be associated with a higher probability of transmission.

Long PCRs of Transposons in the Structural Analysis of Genes Encoding Acquired Glycopeptide Resistance in Enterococci

BioTechniques, 1998
Glycopeptide-resistant enterococci (GRE) associated with multiple antibiotic resistance present a major challenge to clinical practice and infection control due to limited or nonexistent antimicrobial treatment options.

Glycopeptide resistance in Enterococcus spp. and coagulase-negative staphylococci from hospitalised patients in Germany: occurrence, characteristics and dalbavancin susceptibility

Journal of Global Antimicrobial Resistance, 2022
: Objectives: The aim of this study was to evaluate the occurrence of glycopeptide resistance in enterococci and coagulase-negative staphylococci (CoNS) and to determine the susceptibilities of the identified glycopeptide-resistant isolates to ...

Nanopore Long‐Read Metagenomics Reveals Pollution‐Driven Antibiotic Resistance and Xenobiotic Degradation in Urban Beach Microbiomes

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Using nanopore metagenomics, this study reveals that anthropogenic pollution drives ecological and functional shifts in coastal microbiomes. Pristine island environments act as stable, Prochlorococcus‐dominated baselines, whereas urban beaches function as hotspots for opportunistic taxa, harbouring a robust genomic potential for xenobiotic degradation ...

Moderate‐Temperature Hydrothermal Treatment Removes Detectable DNA and Antibiotic Resistance Genes From Municipal Sludge While Preserving Resource Value

Water and Environment Journal, Volume 40, Issue 3, Page 484-494, August 2026.
This graphical abstract shows the overall study design where dewatered wastewater sludge samples were collected and subjected to a range of HT temperatures. Measurement of nucleic acid concentration and antibiotic resistance gene profiles across temperatures showed that HT at moderate temperatures offers sustainable, scalable sludge sanitation and ARG ...

Clostridium clostridioforme and Atopobium minutum Clinical Isolates with VanB-Type Resistance in France [PDF]

Journal of Clinical Microbiology, 2011
ABSTRACT Acquired vancomycin resistance in Gram-positive anaerobes has been reported only in Australia and Canada from rare vanB -positive stool samples in the absence of vancomycin-resistant enterococci (VRE). We report the emergence of VanB-type resistance in Clostridium clostridioforme

Faster and economical screening for vancomycin-resistant enterococci by sequential use of chromogenic agar and real-time polymerase chain reaction

Journal of Microbiology, Immunology and Infection, 2017
Background/Purpose: Screening for vancomycin-resistant enterococci (VRE) by culture takes days to generate results, while polymerase chain reaction (PCR) testing directly from clinical specimens lacks specificity. The aims of this study were to develop a

Enzymatic DNA Reaction Networks for Orchestrating Stimuli‐Dependent Temporal Molecular Pulse

Advanced Science, Volume 13, Issue 38, 9 July 2026.
We present an enzymatic DNA reaction network (EDRN) that encodes nucleic‐acid targets in time, converting inputs into a universal strand and then into programmable transient fluorescence pulses. With time‐color multiplexing, EDRN enables single‐tube high‐plex nucleic acid detection and shows strong agreement with clinical sequencing across 32 specimens.

Transferable, Plasmid-Mediated VanB-Type Glycopeptide Resistance in Enterococcus faecium [PDF]

Antimicrobial Agents and Chemotherapy, 1998
ABSTRACT An approximately 60-kb transferable, vanB -carrying plasmid has been identified in a clinical Enterococcus faecium strain. A similar plasmid has been observed in an unrelated E. faecium strain, suggesting that plasmid transfer of vanB
