Determination of Trace Rare Earth Elements in Tungsten-Molybdenum Ore by Inductively Coupled Plasma-Mass Spectrometry with Microwave Digestion System

open access: yesYankuang ceshi, 2023
BACKGROUNDTungsten-molybdenum ore and rare earth are both important strategic resources. It is of great significance to evaluate the contents of rare earth elements in tungsten-molybdenum ore for the development of rare earth resources in minerals ...

Trends in ExPEC serogroups in the UK and their significance [PDF]

open access: yesEuropean Journal of Clinical Microbiology & Infectious Diseases, 2016
Extra-intestinal pathogenic Escherichia coli are a significant cause of urinary tract infection and bacteraemia within the UK. We sought to identify the serogroups of 658 E. coli isolates collected in the UK between January 2011 and March 2012, to better understand the ExPEC population and understand the relevance of serogroups in this pathotype ...

Global Extraintestinal Pathogenic Escherichia coli (ExPEC) Lineages [PDF]

open access: yesClinical Microbiology Reviews, 2019
Extraintestinal pathogenic Escherichia coli (ExPEC) strains are responsible for a majority of human extraintestinal infections globally, resulting in enormous direct medical and social costs. ExPEC strains are comprised of many lineages, but only a subset is responsible for the vast majority of infections.

Selection and characterization of siderophores of pathogenic Escherichia coli intestinal and extraintestinal isolates

open access: yesOpen Agriculture, 2021
Microorganisms adopt a unique mechanism for sequestration and transport of bound iron by producing iron-chelating molecules called siderophores. Siderophores play an important role in colonization of microbes in iron-deficient sites of the host, hence ...

Virulence potential of antimicrobial-resistant extraintestinal pathogenic Escherichia coli from retail poultry meat in a Caenorhabditis elegans model

open access: yesJournal of Food Protection, 2023
Healthy poultry can be a reservoir for extraintestinal pathogenic Escherichia coli (ExPEC), some of which could be multidrug resistant to antimicrobials.

Deep Learning and Time-Series Analysis for the Early Detection of Lost Circulation Incidents During Drilling Operations

open access: yesIEEE Access, 2021
Drilling operations consist of breaking the rock to deepen a wellbore for oil or gas extraction. A drilling fluid, circulating from the surface through the drill pipe and from the annulus to the surface, is used to remove rock cuttings and maintain ...

Hybrid Atypical Enteropathogenic and Extraintestinal Escherichia coli (aEPEC/ExPEC) BA1250 Strain: A Draft Genome [PDF]

open access: yesPathogens, 2021
Diarrheagenic Escherichia coli is the major bacterial etiological agent of severe diarrhea and a major concern of public health. These pathogens have acquired genetic characteristics from other pathotypes, leading to unusual and singular genetic combinations, known as hybrid strains and may be more virulent due to a set of virulence factors from more ...

Reductions in bacterial viability stimulate the production of Extra-intestinal Pathogenic Escherichia coli (ExPEC) cytoplasm-carrying Extracellular Vesicles (EVs).

open access: yesPLoS Pathogens, 2022
Extra-intestinal Pathogenic Escherichia coli (ExPEC) is defined as an extra-intestinal foodborne pathogen, and several dominant sequence types (STs) ExPEC isolates are highly virulent, with zoonotic potential.

Extraintestinal Pathogenic Escherichia coli Utilizes Surface-Located Elongation Factor G to Acquire Iron from Holo-Transferrin

open access: yesMicrobiology Spectrum, 2022
Extraintestinal pathogenic Escherichia coli (ExPEC) can cause systemic infections in both humans and animals. As an essential nutrient, iron is strictly sequestered by the host. Circumventing iron sequestration is a determinant factor for ExPEC infection.
