Food Science &Nutrition, Volume 11, Issue 1, Page 228-235, January 2023., 2023 Escherichia coli serogroup O157 is the main causative agent of several intestinal and extra‐intestinal foodborne diseases in human through consumption of low‐dose contaminated foods such as milk, beef and vegetables. To date, studies regarding the quantitative prevalence of E. coli O157 in foods are so limited.

Transcriptomic Analysis of Shiga-Toxigenic Bacteriophage Carriage Reveals a Profound Regulatory Effect on Acid Resistance in Escherichia coli [PDF]
, 2015 Shiga-toxigenic bacteriophages are converting lambdoid phages that impart the ability to produce Shiga toxin to their hosts. Little is known about the function of most of the genes carried by these phages or the impact that lysogeny has on the ...

Antimicrobial Resistance and Infection Control, 2018 Background Shiga-toxigenic Escherichia coli strains are one of the most important foodborne bacteria with an emergence of antibiotic resistance. Foodborne STEC strains are mainly associated with presence of certain virulence factors and O-seogroups.

Laboratory Practices and Incidence of Non-O157 Shiga Toxin–producing Escherichia coli Infections
Emerging Infectious Diseases, 2012 We surveyed laboratories in Washington State, USA, and found that increased use of Shiga toxin assays correlated with increased reported incidence of non-O157 Shiga toxin–producing Escherichia coli (STEC) infections during 2005–2010.

A toxin hunter in the microworld of bacteria: a project on novel inhibitors against bacterial AB5 toxins [PDF]
, 2016 [要旨] 病原性細菌が産生する蛋白性のAB5型トキシンは1個のAサブユニットと5個のBサブユニットから構成される外毒素である。両サブユニットはそれぞれ特徴的な役割を持ち，互いに巧妙に機能分担をして一つのトキシンを形成している。Aサブユニットは主に毒性に直接関与する特異的な酵素活性を有する。一方，Bサブユニットは標的細胞のレセプターに対する結合能を有し，AB5型トキシンを標的細胞に吸着させる。ここでは毒性が全く異なるAB5型トキシンとして，コレラ菌が産生するコレラトキシン（CT ...

Identification of the long polar fimbriae gene variants in the locus of enterocyte effacement-negative Shiga toxin-producing Escherichia coli strains isolated from humans and cattle in Argentina [PDF]
, 2010 The long polar fimbriae (Lpf) is one of few adhesive factors of Shiga toxin-producing Escherichia coli (STEC) and it is associated with colonization of the intestine. Studies have demonstrated the presence of lpf genes in several pathogenic E.
