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

PLoS 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

Microbiology 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.

High-Risk ExPEC from Commensal Phylogroup A: Genomic Characterization of a Bovine Meningoencephalitis Isolate, BN01. [PDF]

Microorganisms
Extraintestinal pathogenic Escherichia coli (ExPEC) causes severe infections in humans and animals, yet bovine isolates remain poorly characterized. Here, we report the first complete genome of a bovine ExPEC strain, BN01 (serotype O101:H9-ST10-phylogroup A), isolated from calf meningoencephalitis.

Development and evaluation of foam-based conformance control for a high-salinity and high-temperature carbonate

Journal of Petroleum Exploration and Production Technology, 2018
The extreme heterogeneity of carbonate reservoirs in the form of fracture corridors and super-permeability thief zones present challenges to the efficient sweep of oil in both secondary and tertiary recovery operations.

Cyclooxygenase-2 Inhibition Reduces Autophagy of Macrophages Enhancing Extraintestinal Pathogenic Escherichia coli Infection

Frontiers in Microbiology, 2020
Extraintestinal pathogenic Escherichia coli (ExPEC) is one of the top pathogens responsible for bloodstream infection and severe, often fatal, sepsis. Although the virulence factors and host immune responses to ExPEC infection have been investigated, the

TolC Promotes ExPEC Biofilm Formation and Curli Production in Response to Medium Osmolarity [PDF]

BioMed Research International, 2014
While a high osmolarity medium activates Cpx signaling and causes CpxR to represscsgDexpression, and efflux protein TolC protein plays an important role in biofilm formation inEscherichia coli,whether TolC also responds to an osmolarity change to regulate biofilm formation in extraintestinal pathogenicE. coli(ExPEC) remains unknown.

Whole genome sequencing of an ExPEC that caused fatal pneumonia at a pig farm in Changchun, China [PDF]

BMC Veterinary Research, 2017
In recent years, highly frequent swine respiratory diseases have been caused by extraintestinal pathogenic Escherichia coli (ExPEC) in China. Due to this increase in ExPECs, this bacterial pathogen has become a threat to the development of the Chinese swine industry.

A Novel PhoP/PhoQ Regulation Pathway Modulates the Survival of Extraintestinal Pathogenic Escherichia coli in Macrophages

Frontiers in Immunology, 2018
The extraintestinal pathogenic Escherichia coli (ExPEC) is a typical facultative intracellular bacterial pathogen. Sensing the environmental stimuli and undertaking adaptive change are crucial for ExPEC to successfully colonize in specific ...

Evaluation of Escherichia coli isolates from healthy chickens to determine their potential risk to poultry and human health.

PLoS ONE, 2017
Extraintestinal pathogenic Escherichia coli (ExPEC) strains are important pathogens that cause diverse diseases in humans and poultry. Some E. coli isolates from chicken feces contain ExPEC-associated virulence genes, so appear potentially pathogenic ...
