One day in Denmark: whole-genome sequence-based analysis of Escherichia coli isolates from clinical settings.
J Antimicrob Chemother
January 2025
Technical University of Denmark, National Food Institute, Kongens Lyngby, Denmark.
Background: WGS can potentially be routinely used in clinical microbiology settings, especially with the increase in sequencing accuracy and decrease in cost. Escherichia coli is the most common bacterial species analysed in those settings, thus fast and accurate diagnostics can lead to reductions in morbidity, mortality and healthcare costs.
Objectives: To evaluate WGS for diagnostics and surveillance in a collection of clinical E.
Green synthesis of silver nanoparticles from the endophytic fungus Panax notoginseng and their antioxidant and antimicrobial activities and effects on cherry tomato preservation.

College of Animal Science and Technology, Yangtze University, Jingzhou 434023, China. Electronic address:
This study investigated endophytic fungi isolated from the medicinal plant Panax notoginseng. Among these, the endophytic fungus SQ3, identified as Chaetomium globosum, was capable of reducing silver ions to form metallic silver nanoparticles. The green-synthesized silver nanoparticles (AgNPs) presented a distinct surface plasmon resonance peak at 424 nm, with particle sizes between 2.

Ann Clin Microbiol Antimicrob
January 2025
Laboratoire de Bactériologie, CHU Félix Guyon, Allée des Topazes, 97400, Saint-Denis, La Réunion, France.
Aim: Located in the Southwest Indian Ocean area (SIOA), the two French overseas territories (FOTs) of Reunion and Mayotte islands are heavily impacted by antimicrobial resistance. The aim of this study was to investigate all cases of NDM-5 and OXA-181 carbapenemase-producing Escherichia coli (CPEc) in these two FOTs between 2015 and 2020, to better understand the regional spread of these last-line treatment resistant bacteria.

Prevalence of common diarrheagenic enterobacteriaceae in Iran (2000-2023): a systematic review and meta-analysis.
BMC Gastroenterol
January 2025
Department of Biostatistics, Payame Noor University, Karaj, Iran.
Objective: Bacterial gastroenteritis is a significant public health concern, capable of causing severe infections. Among the various pathogens involved, those belonging to the Enterobacteriaceae family are the most frequently isolated and associated with gastrointestinal disorders. This study aimed to investigate the prevalence of common diarrheagenic Enterobacteriaceae in Iran over the past two decades, from 2000 to 2023.

Universidad San Francisco de Quito, Colegio de Ciencias Biológicas Ambientales, Instituto de Microbiología, Quito, Ecuador.
Aim: To investigate the nucleotide sequences associated with transposable elements carrying bla allelic variants as potential markers for the transmission of antimicrobial resistance genes between domestic animals, humans and the environment.
Materials & Methods: We conducted whole-genome sequencing and analyzed the nucleotide sequences of most abundant bla allelic variants (bla, bla, and bla) in commensal Escherichia coli ( = 20) from household members in Quito and uropathogenic E. coli (UPEC) ( = 149) isolated from nine clinics in Quito, Ecuador.
