Objective: The study is focused on evaluating the efficacy of seaweed flavonoids against staphylococcus enterotoxin A. Methods: drug-likeness and pharmacological properties chosen ligand were evaluated using SWISS ADME. AutoDockTools-1.5.6 was used to carry out docking analysis determine binding parameters with molecular modeling. Docking visualization performed discovery studio. Results: bioac...

The epidemiological and bacteriological investigations on four foodborne outbreaks caused by a new type of enterotoxin-producing Clostridium perfringens are described. C. perfringens isolated from patients of these outbreaks did not produce any known enterotoxin and did not carry the C. perfringens enterotoxin gene. However, the culture filtrates of these isolates induced the accumulation of fl...

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. The enterotoxin was designated enterotoxin E.

Staphylococcal enterotoxin types A and C, were observed by viscosimetry and near-ultraviolet difference spectroscopy to unfold at concentrations of aqueous guanidine hydrochloride greater than 1 M. Apparent rate constants of unfolding calculated from spectral curves differed markedly for the two enterotoxins. Rate constants for the unfolding of enterotoxin A in 2 or 3 M guanidine hydrochloride ...

Sixty-nine strains of Clostridium perfringens of different toxigenic types were investigated for enterotoxin production. Enterotoxin was definitively detected only in strains of types A and C. This is the first report where enterotoxin production has been demonstrated in a toxigenic type other than type A. The exterotoxin-positive type C strains were isolated from cases of enteritis necroticans...

Detection and Frequency of Enterotoxin (cpa,cpe) Genes Clostridium perfringens Isolated from Dehydrated Vegetables by PCR

yersinia enterocolitica is newly included in the classification of both the invasive bacteria, e.g. shigella, and the toxicogenic bacteria, e.g. escherichia coli. five human strains and 45 environmental strains were used to produce y.enterocolitical enterotoxin at 40c, 240c and 370c using infant mouse assay. at 250c enterotoxin was produced by 10 environmental strains and by all of the 3 human ...

elaboration of different toxins by enterotoxigenic e. coli has been considered as one of the main virulence factors contributing to the manifestation of disease caused by these microorganisms. various strategies have been employed to raise antibodies against these toxins as a line of defense. in this study, the 3’ terminus of the gene that codes for the binding subunit of the heat-labile entero...
