Identification of Potential Vaccine Strains of Escherichia coli Isolates From Diarrhoeic Calves

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study aimed to identify vaccine candidate Escherichia coli strains isolated from diarrheic calves. Faecal samples collected from 500 calves were analysed, and E. coli strains were isolated and characterized phenotypically and genotypically. Antibiotic resistance profiles, virulence‐associated genes and MLVA genotyping were used to select 20 ...

Monoclonal Antibody 11E10, Which Neutralizes Shiga Toxin Type 2 (Stx2), Recognizes Three Regions on the Stx2 A Subunit, Blocks the Enzymatic Action of the Toxin In Vitro, and Alters the Overall Cellular Distribution of the Toxin [PDF]

Infection and Immunity, 2009
ABSTRACT Monoclonal antibody (MAb) 11E10 recognizes the Shiga toxin type 2 (Stx2) A 1 subunit. The binding of 11E10 to Stx2 neutralizes both the cytotoxic and lethal activities of Stx2, but the MAb does not bind to or neutralize Stx1 despite the 61% identity and 75% similarity in the amino acids of the A

Selective Evolution of Ligands by Exponential Enrichment to Identify RNA Aptamers against Shiga Toxins

Journal of Nucleic Acids, 2014
Infection with Shiga toxin- (Stx-) producing E. coli causes life threatening hemolytic uremic syndrome (HUS), a leading cause of acute renal failure in children. Of the two antigenically distinct toxins, Stx1 and Stx2, Stx2 is more firmly linked with the

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

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
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

Detection of stx1 and stx2 Genes in Pennsylvanian White-Tailed Deer

Toxins, 2011
Shiga toxin-producing E. coli carrying the stx1 and/or stx2 genes can cause multi-symptomatic illness in humans. A variety of terrestrial and aquatic environmental reservoirs of stx have been described. Culture based detection of microbes in deer species have found a low percentage of samples that have tested positive for Stx-producing microbes ...

Short communication: Detection of stx2 and elt genes in bovine milk by using a multiplex PCR system [PDF]

Journal of Dairy Science, 2017
The aim of this study was to detect 2 important toxin genes from diarrheagenic Escherichia coli (DEC) in bovine milk using a new multiplex PCR. To standardize the multiplex PCR, the stx2 and elt genes were investigated for the detection of Shiga toxin-producing Escherichia coli (STEC) and enterotoxigenic E. coli (ETEC), respectively.

Functional capacity of Shiga-toxin promoter sequences in eukaryotic cells. [PDF]

PLoS ONE, 2013
Shiga toxins (Stx) are the main virulence factors in enterohemorrhagic Escherichia coli (EHEC) infections, causing diarrhea and hemolytic uremic syndrome (HUS). The genes encoding for Shiga toxin-2 (Stx2) are located in a bacteriophage.
