Diversity and Molecular Characterization of Shiga Toxin-producing Escherichia coli Isolated from Ground Beef at Point of Sale in Hidalgo, Mexico

Journal of Pure and Applied Microbiology
Shiga toxin-producing Escherichia coli (STEC) is the causative agent of several epidemic outbreaks worldwide. STEC infections range from mild diarrhea to fatal outcomes, transmission occurs mainly through the ingestion of contaminated and undercooked ...

Food Safety and Nutritional Aspects of Plant‐Based Dairy and Meat Alternatives: A Review

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
Plant‐based dairy and meat alternatives (PBDA and PBMA) offer sustainability benefits but also introduce chemical and microbiological hazards to the diet. Key concerns include emerging mycotoxins, heavy metals, process contaminants, and heat‐resistant spore‐forming bacteria.

Identification of Novel Biomarkers for Priority Serotypes of Shiga Toxin-Producing Escherichia coli and the Development of Multiplex PCR for Their Detection

Frontiers in Microbiology, 2018
It would be desirable to have an unambiguous scheme for the typing of Shiga toxin-producing Escherichia coli (STEC) isolates to subpopulations. Such a scheme should take the high genomic plasticity of E.

Shiga Toxin-Producing Escherichia coli in Plateau Pika (Ochotona curzoniae) on the Qinghai-Tibetan Plateau, China

Frontiers in Microbiology, 2016
Shiga toxin-producing Escherichia coli (STEC) are an emerging group of zoonotic pathogens. Ruminants are the natural reservoir of STEC. In this study we determined the prevalence and characteristics of the STEC in plateau pika (Ochotona curzoniae) on the

Genomic Characterization of β-Glucuronidase–Positive Escherichia coli O157:H7 Producing Stx2a

Emerging Infectious Diseases, 2018
Among Shiga toxin (Stx)–producing Escherichia coli (STEC) O157:H7 strains, those producing Stx2a cause more severe diseases. Atypical STEC O157:H7 strains showing a β-glucuronidase–positive phenotype (GP STEC O157:H7) have rarely been isolated from ...

Detection of the mcr-1 gene in Enteropathogenic Escherichia coli (EPEC) and Shigatoxigenic E. coli (STEC) strains isolated from broilers

Pesquisa Veterinária Brasileira
: Enteropathogenic Escherichia coli (EPEC) and Shigatoxigenic E. coli (STEC) strains are among the major pathotypes found in poultry and their products, which are capable of causing human enteric infections.

Therapeutic concentrations of antibiotics inhibit Shiga toxin release from enterohemorrhagic E. coli O104:H4 from the 2011 German outbreak

BMC Microbiology, 2012
Background The shiga toxin-producing E. coli (STEC) O104:H4 caused a major outbreak in Germany in spring 2011. STEC are usually susceptible to common antibiotics. However, antibiotic treatment of STEC-infected patients is not recommended because STEC may

Shiga toxin-producingE. coli(STEC) in swine: prevalence over the finishing period and characteristics of the STEC isolates

Epidemiology and Infection, 2014
SUMMARYThis descriptive longitudinal study was conducted to investigate the faecal shedding of Shiga toxin-producingE. coli(STEC) in finishing swine and to characterize the swine STEC isolates that were recovered. Three cohorts of finishing swine (n = 50/cohort; total 150 pigs) were included in the longitudinal study.

Escherichia coli in Chicken Carcasses in Southern Brazil: Absence of Shigatoxigenic (STEC) and Isolation of Atypical Enteropathogenic (aEPEC)

Brazilian Journal of Poultry Science
The aim of this study was to investigate the presence of shiga toxin-producing Escherichia coli (STEC) and atypical enteropathogenic Escherichia coli (aEPEC) in frozen chicken carcasses sold at stores in southern Brazil. Typical E.

Neutralizing antibodies in the intestinal mucosa are essential to control gastrointestinal infection by Shiga toxin‐producing Escherichia coli

mLife
Infections with Shiga toxin (Stx)‐producing Escherichia coli (STEC) strains can result in a wide range of clinical presentations. Despite STEC O157:H7 being the serotype most frequently associated with hemolytic uremic syndrome (HUS), in some patients, a
