Enterotoxin gene profile of Staphylococcus aureus isolates recovered from bovine milk produced in central Ethiopia

open access: yesJournal of Infection in Developing Countries, 2016
Introduction: Staphylococcal food intoxication is dependent on the production of enterotoxins, the single most important virulence factors. Various studies conducted in Ethiopia have depicted the prevalence of S. aureus in bovine milk.

Resistance of Bacillus cereus and its enterotoxin genes in ready-to-eat foods to γ-irradiation

open access: yes, 2012
This research article published by Springer Nature Switzerland AG., 2012This study was investigated the resistance of Bacillus cereus ATCC 13752 and its enterotoxin coding genes in cereals, vegetables, and tryptic soy broth to γ-irradiation.

Identification of Enterotoxin E [PDF]

open access: yesInfection and Immunity, 1971
Identification of a new enterotoxin was accomplished by purification of the enterotoxin produced by staphylococcal strain FRI-326 and by preparation of specific antitoxin to the enterotoxin. Toxicity of the preparations was determined in rhesus monkeys, and specificity of the enterotoxin-antitoxin reaction was determined in gel diffusion plates.

Production of a mouse antiserum to Bacteroides fragils using a recombinant enterotoxin precursor

open access: yes, 2001
The precursor of the Bacteroides fragilis metalloprotease enterotoxin was cloned and expressed in Escherichia coli, which was not able to process the precursor into the biologically active enterotoxin.

Effects of Bile Acids and Nisin on the Production of Enterotoxin by Clostridium perfringens in a Nutrient-Rich Medium

open access: yesInternational Journal of Microbiology, 2018
Clostridium perfringens is the second most common cause of bacterial foodborne illness in the United States, with nearly a million cases each year. C. perfringens enterotoxin (CPE), produced during sporulation, damages intestinal epithelial cells by pore

The Biochemical Activity of Enterotoxin and Non-Enterotoxin Producing Staphylococci

open access: yesActa Veterinaria Scandinavica, 1977
One hundred and sixty-nine staphylococcal strains of human origin have been tested for production of enterotoxin A, B or Ci, coagulase activity, DNase activity, typical growth on ETGP-agar, hemolysin production and the breakdown of mannitol under aerobic conditions.

Salmonella enterica serovar typhi limits the potency of typhoid toxin and ADP‐ribosylating toxin AB to establish a persistent infection

open access: yesFEBS Open Bio, EarlyView.
The two catalytic subunits of typhoid toxin dissociate from the holotoxin in the ER of an intoxicated cell, but only CdtB exits the ER to generate immunosuppressive effects. PltA is retained in the ER and sequestered from its cytosolic target, thus allowing the anti‐inflammatory effects of CdtB to promote intestinal colonization.

A Drug‐Gated, Modular STAb‐T Immunotherapy With External Control

open access: yesAdvanced Science, EarlyView.
Engineered STAb‐TON cells act as programmable living factories that continuously secrete inactive antibody modules, which assemble extracellularly into a functional T cell engager only upon small‐molecule administration. This externally controlled platform enables reversible, on‐demand regulation of antitumor immunity, establishing a new paradigm for ...

Plesiomonas shigelloides exports a lethal cytotoxic-enterotoxin (LCE) by membrane vesicles

open access: yesBrazilian Journal of Infectious Diseases, 2016
Plesiomonas shigelloides isolated from water in Brazil was previously described as a hemorrhagic heat-labile cytotoxic-enterotoxin producer. We purified this toxin from culture supernatants using ion metallic affinity chromatography (IMAC) followed by ...

Effect of (−)-Epigallocatechin Gallate to Staphylococcal Enterotoxin A on Toxin Activity

open access: yesMolecules, 2020
Staphylococcal enterotoxin A (SEA) functions both as superantigens that stimulate non-specific T cell proliferation as well as potent gastrointestinal toxins. We previously reported that (−)-epigallocatechin gallate (EGCG) binds to SEA.
