Enterohemorrhagic Escherichia coli O157:H7: case report

The Turkish Journal of Pediatrics, 2008
Enterohemorrhagic Escherichia coli (EHEC) is a significant bacterial pathogen of bloody diarrhea. Not only does it cause systemic complications, such as hemolytic uremic syndrome (HUS) (the most common cause of potentially preventable pediatric ...

Enterococcus faecalis Enhances Expression and Activity of the Enterohemorrhagic Escherichia coli Type III Secretion System

mBio, 2019
The gut microbiota can significantly impact invading pathogens and the disease they cause; however, many of the mechanisms that dictate commensal-pathogen interactions remain unclear.

Intimate Attachment of Escherichia coli O157:H7 to Urinary Bladder Epithelium in the Gnotobiotic Piglet Model

Microorganisms, 2020
Enterohemorrhagic Escherichia coli (EHEC), a pathogenic subset of Shiga toxin-producing E. coli (STEC), is an important cause of hemorrhagic colitis and hemolytic−uremic syndrome (HUS), and a rare cause of urinary tract infections (UTIs) with ...

YkgM and ZinT proteins are required for maintaining intracellular zinc concentration and producing curli in enterohemorrhagic Escherichia coli (EHEC) O157:H7 under zinc deficient conditions

, 2016
Zn2+ uptake systems are required for many enteric pathogens to survive and form biofilm in zinc-deficient conditions. ykgM and zinT (formerly yodA), regulated by Zur (zinc uptake regulator), have been reported as being highly induced during zinc shortage.

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

Comprehensive 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.

Pathogenic Escherichia coli Hijacks GTPase-Activated p21-Activated Kinase for Actin Pedestal Formation

mBio, 2019
Enteropathogenic Escherichia coli and enterohemorrhagic E. coli (EPEC and EHEC, respectively) are extracellular pathogens that reorganize the host cell cytoskeleton to form “actin pedestals” beneath the tightly adherent bacteria, a critical step in ...

IGLR-2, a Leucine-Rich Repeat Domain Containing Protein, Is Required for the Host Defense in Caenorhabditis elegans

Frontiers in Immunology, 2020
Enterohemorrhagic Escherichia coli (EHEC), a human pathogen, also infects Caenorhabditis elegans. We demonstrated previously that C. elegans activates the p38 MAPK innate immune pathway to defend against EHEC infection. However, whether a C.

Beer Production With Umbu (Spondias tuberosa) Using Conventional and Nonconventional Yeast

Journal of Food Science, Volume 91, Issue 1, January 2026.
ABSTRACT This study evaluated the fermentation performance and bioactive properties of beers produced by Pichia kluyveri L131 and commercial Saccharomyces pastorianus, individually and in coculture, in wort enriched with umbu pulp. Fermentation profiles were assessed over 12 days, focusing on yeast population dynamics, carbohydrate consumption, and ...

Data_Sheet_1_Persistent Circulation of Enterohemorrhagic Escherichia coli (EHEC) O157:H7 in Cattle Farms: Characterization of Enterohemorrhagic Escherichia coli O157:H7 Strains and Fecal Microbial Communities of Bovine Shedders and Non-shedders.docx

, 2022
Cattle are carriers, without clinical manifestations, of enterohemorrhagic Escherichia coli (EHEC) O157:H7 responsible for life-threatening infections in humans. A better identification of factors playing a role in maintaining persistence of such strains

The yad and yeh fimbrial loci influence gene expression and virulence in enterohemorrhagic Escherichia coli O157:H7

mSphere
Fimbriae are essential virulence factors for many bacterial pathogens. Fimbriae are extracellular structures that attach bacteria to surfaces. Thus, fimbriae mediate a critical step required for any pathogen to establish infection by anchoring a ...
