The predominance of Shiga toxin-producing E. coli in the Southeast Coast of India

open access: yesMarine Pollution Bulletin, 2022
In this study, we reported Shiga toxin-producing Escherichia coli (STEC) in 847 samples, including those in coastal waters, sediments, and fish samples in the Southeast Coast of India. A total of 3742 E. coli strains were identified using conventional and molecular identification methods. Of these, 1518 isolates expressed virulent genes Stx1, Stx2, and

The Occurrence of Shiga Toxin-Producing E. coli in Aquaponic and Hydroponic Systems [PDF]

open access: yesHorticulturae, 2020
Food safety concerns have been raised over vegetables and herbs grown in aquaponics and hydroponics due to the reuse of wastewater and spent nutrient solutions. This study was conducted to determine the occurrence of foodborne pathogens in greenhouse-based aquaponic and hydroponic systems. Fish feces, recirculating water, roots, and the edible portions

Nanobody-Based Bispecific Neutralizer for Shiga Toxin-Producing E. coli

open access: yesACS Infectious Diseases, 2022
Currently, no specific therapeutics are available for foodborne Shiga toxin-producing Escherichia coli (STEC) infections that cause severe gastroenteritis and life-threatening complications of hemolytic uremic syndrome (HUS). As STEC attachment to intestinal epithelium might increase the host absorption of Shiga toxins and severity of the disease, we ...

Inhibition of development of Shiga toxin-converting bacteriophages by either treatment with citrate or amino acid starvation [PDF]

open access: yes, 2012
Objectives: Shiga toxin–producing Escherichia coli (STEC) are pathogenic strains, whose virulence depends on induction of Shiga toxin–converting prophages and their subsequent lytic development.

Characterizing RecA-Independent Induction of Shiga toxin2-encoding Phages by EDTA Treatment [PDF]

open access: yes, 2012
The bacteriophage life cycle has an important role in Shiga toxin (Stx) expression. The induction of Shiga toxin-encoding phages (Stx phages) increases toxin production as a result of replication of the phage genome, and phage lysis of the host cell also

Characteristics of Bacteriophage Isolates and Expression of Shiga Toxin Genes Transferred to Non Shiga Toxin-Producing E. coli by Transduction. [PDF]

open access: yesJ Microbiol Biotechnol, 2021
A risk analysis of Shiga toxin (Stx)-encoding bacteriophage was carried out by confirming the transduction phage to non-Stx-producing Escherichia coli (STEC) and subsequent expression of the Shiga toxin genes. The virulence factor stx1 was identified in five phages, and both stx1 and stx2 were found in four phages from a total of 19 phage isolates with

Bacteriophages to control Shiga toxin-producing E. coli – safety and regulatory challenges [PDF]

open access: yesCritical Reviews in Biotechnology, 2020
Shiga toxin-producing Escherichia coli (STEC) are usually found on food products due to contamination from the fecal origin, as their main environmental reservoir is considered to be the gut of ruminants. While this pathogen is far from the incidence of other well-known foodborne bacteria, the severity of STEC infections in humans has triggered global ...

Electrochemical nucleic acid-based sensors for detection of E. coli and Shiga toxin-producing E. coli (STEC) – Review of the recent developments [PDF]

open access: yes, 2022
Escherichia coli (E. coli) are a group of bacteria, which are a natural part of the intestinal flora of warm-blooded animals, including humans. Most E.

Intimin, tir, and shiga toxin 1 do not influence enteropathogenic responses to shiga toxin-producing Escherichia coli in bovine ligated intestinal loops [PDF]

open access: yes, 2002
Shiga toxin-producing Escherchia coli (STEC) comprises a group of attaching and effacing (A/E) enteric pathogens of animals and humans. Natural and experimental infection of calves with STEC may result in acute enteritis or subclinical infection ...

Isolation and Characterization of Shiga Toxin-Associated Microvesicles

open access: yes, 2021
Microvesicles are shed from cell surfaces during infectious or inflammatory conditions and may contribute to the pathogenesis of disease. During Shiga toxin-producing Escherichia coli (STEC) infection, microvesicles are released from blood cells.
