Occurrence of Multiple stx1 Genes and Rare Genomic Variation in stx1 Shiga Toxin-Producing Escherichia coli

open access: yesMicroorganisms
Shiga toxin-producing Escherichia coli are important foodborne pathogens. There are several subtypes of the Shiga toxin Stx known, with Stx2 (a–o) being more diverse than Stx1 (a, c, d).

Baicalein Inhibits Stx1 and 2 of EHE: Effects of Baicalein on the Cytotoxicity, Production, and Secretion of Shiga Toxins of Enterohaemorrhagic Escherichia coli [PDF]

open access: yesToxins, 2019
Shiga toxin-producing enterohaemorrhagic Escherichia coli (EHEC) O157:H7 is an important foodborne pathogen. Baicalein (5,6,7-trihydroxylflavone), a flavone isolated from the roots of Scutellaria baicalensis, is considered as a potential antibacterial ...

Antimicrobials resistance patterns and the presence of stx1, stx2 and eae in Escherichia coli [PDF]

open access: yesRevista Brasileira de Saúde e Produção Animal, 2015
The objectives of this study were to investigate whether antimicrobial resistance (AMR) or the presence of resistance genes was associated with the occurrence of the virulence genes, stx1, stx2 andeae. Three virulence genes and 11 AMR phenotypes were examined using polymerase chain reaction (PCR) and antimicrobial susceptibility tests. From 800 samples

Effect of Escherichia coli Stx1 on the cytokine profile of bovine ileal intraepithelial lymphocytes [PDF]

open access: yes, 2006
Escherichia coli Shiga toxin 1 (Stx1) blockiert die Aktivierung boviner peripherer (PBMC) und ilealer intraepithelialer Lymphozyten (iIEL). Ziel dieser Untersuchung war es, den Einfluss von Stx1 auf die Expression ausgewählter Chemokin- und Zytokin-Gene in vitro mit Hilfe der real-time RT-PCR und der intrazellulären Quantifizierung zweier Zytokin ...

A novel transducible chimeric phage from Escherichia coli O157:H7 Sakai strain encoding Stx1 production

open access: yesInfection, Genetics and Evolution, 2015
Shiga toxin-producing Escherichia coli (STEC), and especially enterohaemorrhagic E. coli (EHEC) are important, highly virulent zoonotic and food-borne pathogens. The genes encoding their key virulence factors, the Shiga toxins, are distributed by converting bacteriophages, the Stx phages.

Prevalence, Antimicrobial Susceptibility, and Hygienic Practices of Escherichia coli O157:H7 in Raw Meat, Bahir Dar City, Ethiopia. [PDF]

open access: yesVet Med Sci
Escherichia coli O157:H7 was detected in 28.4% of raw meat samples from Bahir Dar City, with 47.6% of isolates carrying at least one stx1 or eaeA virulence gene. Poor hygiene practices and antimicrobial resistance highlight the need for strengthened meat safety surveillance and intervention. ABSTRACT Introduction Escherichia coli O157: H7 is a globally

Prevalence and distribution of the stx1, stx2 genes in Shiga toxin producing E. coli (STEC) isolates from cattle

open access: yesIranian Journal of Microbiology, 2010
Background and Objectives: Shiga toxin-producing Escherichia coli (STEC) strains are human pathogens linked to hemorrhagic colitis and hemolytic uremic syndrome. Shiga toxins (Stx1 and Stx2) are the major virulence factors of these strains.

Evaluation of ehxA, stx1, and stx2 Virulence Gene Prevalence in Cattle Escherichia coli Isolates by Multiplex PCR [PDF]

open access: yes, 2005
Summary Today, it is nearly 25 years past from investigation of Shiga toxigenic Escherichia coli (STEC) which is able to produce Shiga toxins and cause different gastroenteritis. Since incidence of gastroenteritis due to STEC is increasing, it's necessary to develop rapid, specific and accurate procedures like PCR.

Detection and Zoonotic Implications of Shiga Toxin-Producing Escherichia coli in Black Bengal Goats in Bangladesh. [PDF]

open access: yesVet Med Sci
Low prevalence of STEC was detected in Black Bengal goats in Bangladesh; however, isolates carrying stx2, ehxA, saa, and subA highlight the presence of atypical strains with zoonotic potential. Identified risk factors emphasize the need for enhanced surveillance and improved farm hygiene practices to mitigate public health risks.
