Shiga toxin production and translocation during microaerobic human colonic infection with Shiga toxin-producing E. coli O157:H7 and O104:H4 [PDF]

open access: yes, 2014
Haemolytic uraemic syndrome caused by Shiga toxin-producing E. coli (STEC) is dependent on release of Shiga toxins (Stxs) during intestinal infection and subsequent absorption into the bloodstream.

Clinical surveillance of thrombotic microangiopathies in Scotland, 2003-2005 [PDF]

open access: yes, 2007
The prevalence, incidence and outcomes of haemolytic uraemic syndrome (HUS) and thrombotic thrombocytopaenic purpura (TTP) are not well established in adults or children from prospective studies. We sought to identify both outcomes and current management

Molecular Characterization of Virulent Genes and Antimicrobial Resistance Patterns of Escherichia coli Isolated From Calf Scours in Western Iran

open access: yesVeterinary Medicine and Science, Volume 12, Issue 1, January 2026.
This study in Western Iran analysed E. coli in diarrhoeic neonatal calves and identified 307 isolates from 350 faecal samples. The pathotypes included EHEC (36.59%), EPEC (20.42%), ETEC (14.46%), STEC (12.34%) and NTEC (11.48%), with four STEC O157:H7 isolates. Serotypes O103 and O15 were the most common.

Comparative Pathogenicity of Wildlife and Bovine Escherichia coli O157:H7 Strains in Experimentally Inoculated Neonatal Jersey Calves

open access: yesVeterinary Sciences, 2018
Shiga toxin-producing Escherichia coli, like E. coli O157:H7, are important human and animal pathogens. Naturally-acquired E. coli O157:H7 infections occur in numerous species but, particularly, cattle have been identified as a significant reservoir for ...

Facing the D‐Ilemma of Heat Resistance Parameters: From Pathogen Risk Assessment to Surrogate Selection Challenges in the Fruit Juice and Nectar Production

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 1, January 2026.
ABSTRACT Over the years, numerous D‐ and z‐values have been published in the scientific literature. While these values initially appear to be valid criteria for assessing and comparing the heat resistance of different microorganisms under the same conditions or the same microorganism under different conditions, this is not always the case.

Day-to-day dynamics of commensal Escherichia coli in Zimbabwean cows evidence temporal fluctuations within a host-specific population structure [PDF]

open access: yes, 2017
To get insights into the temporal pattern of commensal Escherichia coli populations, we sampled the feces of four healthy cows from the same herd in the Hwange District of Zimbabwe daily over 25 days. The cows had not received antibiotic treatment during

Recent Advances in Lemongrass Essential Oil: Food Safety, Preservation, and Bioactivity in Food Systems

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 1, January 2026.
ABSTRACT Lemongrass essential oil (LGEO) has gained recognition as a natural preservative in food systems due to its distinctive phytochemical composition and multifunctional bioactivities. Dominated by citral and complemented by terpenes and phenolic compounds, LGEO demonstrates potent antibacterial, antifungal, antiviral, antibiofilm, and antioxidant
