A novel dodecadepsipeptide, cereulide, is an emetic toxin of Bacillus cereus.

A vacuole-formation substance, cereulide of Bacillus cereus, is an emetic toxin in animals. Both oral administration and intraperitoneal injection of cereulide caused dose-dependent emesis in Suncus murinus, a new animal model of emesis. Vagotomy or a 5-HT3 receptor antagonist completely abolished this emetic effect. Therefore, cereulide causes emesis through the 5-HT3 receptor and stimulation ...

Quantification of the emetic toxin cereulide in food products by liquid chromatography-mass spectrometry using synthetic cereulide as a standard.

Bacillus cereus produces the emetic toxin cereulide, a cyclic dodecadepsipeptide that can act as a K(+) ionophore, dissipating the transmembrane potential in mitochondria of eukaryotic cells. Because pure cereulide has not been commercially available, cereulide content in food samples has been expressed in valinomycin equivalents, a highly similar cyclic potassium ionophore that is commercially...

Calcium requirement for syncytium formation in HEp-2 cells by respiratory syncytial virus.

Respiratory syncytial virus (RSV) grown in HEp-2 cells in the absence of calcium did not induce cell fusion and syncytium formation. Although the infected cells contained viral antigens, the cytopathic effect (giant cell formation) typical for RSV was not observed in calcium-free cultures. Infectious virus yield was also slightly reduced (less than a one log10 reduction) in the absence of calci...

association between efficient adhesion to hep-2 cells and severity of gastritis in helicobacter pylori strains isolated from children

background and objectives: helicobacter pylori causes chronic gastritis, peptic ulceration, and is a risk factor for gastric cancer. more than half of the world`s population is infected with this pathogen, however the disease outcome varies. among the virulence factors of h. pylori, specific adhesions to gastric epithelium may be an important step in the induction of active inflammation. h. pyl...

Benchmarking HEp-2 Cells Classification Methods

In this paper we report on the first edit ion of the HEp-2 Cells Classificat ion contest , held at the 2012 edit ion of the Internat ional Conference on Pattern Recognit ion, and focused on Indirect Immunofluorescence (IIF) image analysis. The IIF methodology is used to detect autoimmune diseases by searching for ant ibodies in the pat ient serum but, unfortunately, it is st ill a subject ive m...
