Culture-free detection and enumeration of STEC in water

Ecotoxicology and Environmental Safety, 2011
Shiga toxin-producing Escherichia coli (STEC) causes worldwide outbreaks of food and waterborne diseases. Rapid identification of causative agents is critical for early intervention in the case of widespread diarrheal epidemics to prevent mortality.

Molecular confirmation of some virulence genes of E. coli isolated from lambs' colibacillosis [PDF]

Iraqi Journal of Veterinary Sciences
Colibacillosis is an infectious disease caused by pathogenic strains of E. coli, which are considered the most common and significant bacteria that cause dysentery or diarrhea in lambs.

Longitudinal Variation of Ionospheric Irregularities and Response of the Ionosphere During 10–13 May and 10–13 October 2024 Geomagnetic Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We examine the response of the ionosphere to the 10–13 May 2024 and 10–13 October 2024 geomagnetic storms, the two recent great geomagnetic storms of solar cycle 25. We identified the occurrence of ionospheric irregularities during the two geomagnetic storms.

A preliminary study of the use of MinION sequencing to specifically detect Shiga toxin-producing Escherichia coli in culture swipes containing multiple serovars of this species

Scientific Reports, 2023
An important challenge relating to clinical diagnostics of the foodborne pathogen Shiga toxin-producing E. coli (STEC), is that PCR-detection of the shiga-toxin gene (stx) in DNA from stool samples can be accompanied by a failure to identify an STEC ...

Assessing GNSS Reflectometry for High‐Latitude 3D Ionospheric Imaging

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract This study investigates whether Global Navigation Satellite System Reflectometry (GNSS‐R) measurements from low‐Earth‐orbit (LEO) satellites can improve three‐dimensional (3D) ionospheric electron density imaging, with a focus on high‐latitude regions. Conventional ionospheric tomography is limited by sparse ground‐based receiver coverage over

Model‐Based Analysis of Ionospheric TEC Disturbances Over China and Adjacent Regions During the May 2024 Super Geomagnetic Storm

Space Weather, Volume 24, Issue 8, August 2026.
Abstract This study uses observation data from multi‐constellation (GPS/GLONASS/Galileo/BeiDou) ground‐based Global Navigation Satellite Systems (GNSS) networks and a non‐integrated spherical harmonic function modeling methodology to develop an ionospheric Total Electron Content (TEC) model with high spatiotemporal resolution (1° × 1° in longitude and ...

Integration of Blockchain and AI Knowledge Management for Contamination Risk Prediction in Food Logistics

Engineering Reports, Volume 8, Issue 7, July 2026.
An integrated blockchain–AI framework is proposed for proactive contamination risk prediction in food logistics. FSMA Rule 204 traceability records and IoT cold‐chain sensor data are combined with physics‐informed machine learning and federated learning to generate early contamination warnings while preserving data privacy.

Membrane Perturbation and Nutrient Transport Dysregulation Are Conserved Targets of Thyme Essential Oil Against Shiga Toxin‐Producing Escherichia coli on Pea Sprouts

Food Frontiers, Volume 7, Issue 4, July 2026.
ABSTRACT Vegetable sprouts are high‐risk carriers of Shiga toxin‐producing Escherichia coli (STEC), with the emerging “big six” STEC serogroups (e.g., O26, O45, O103, O111, O121, and O145) posing growing threats. Thyme essential oil (EO) is a promising natural sanitizer; however, its effects against different STEC strains remain unclear.

A challenging STEC strain isolation from patients’ stools: an O166:H15 STEC strain with the stx2 gene

Microbiology Spectrum
ABSTRACT Two patients with acute gastroenteritis tested positive for Shiga toxin-producing Escherichia coli (STEC) by polymerase chain reaction (PCR), and both strains carried the Shiga toxin 2 encoding gene. Since routine culture using CHROMagar STEC failed to recover these
