Exosporium Morphogenesis in Bacillus Cereus and Bacillus Anthracis
<p>Bacillus cereus is a Gram-positive spore-forming bacteria that can cause food poisoning and its close relative, Bacillus anthracis is the etiological agent of anthrax. In both cases, the spore, a differentiated cell type in a dormant state, starts the infection process. Thus, the exosporium, …

Molecular typing of virulence genes in enterotoxigenic Bacillus cereus
Bacillus cereus causes emesis and/or diarrhea following ingestion of contaminated food due to the production of emetic toxins and enterotoxins. SYBR Green I is used as an intercalating dye and its florescence increases as a result of DNA amplification during real-time PCR. A second-derivative plot …

Untersuchungen zu Bacillus cereus Enterotoxin-Komplexen auf zellulärer Ebene
… paper deals with the in vitro activity of the B. cereus enterotoxin-complexes Hemolysin BL (HBL) and non-hemolytic enterotoxin (Nhe) on cells. For that purpose the cytotoxic and hemolytic activity of crude B. cereus culture supernatants was analyzed in cell culture assays and on blood agar plates. …

A Role of Intracellular Polysaccharide in the Sporulation of "Bacillus Cereus"
The problem. "Bacillus cereus" accumulates an intracellular polysaccharide under conditions of nutritional stress. The polysaccharide is then degraded as the organism begins sporulation. This study concerns intracellular polysaccharide and its possible involvement in sporulation as a source of …

Molecular analysis of GerP and spore-associated proteins of Bacillus cereus
Spores of various strains of Bacillus cereus are the causative agents of emetic and diarrheal foodborne illnesses. Typically, spores will survive thermal treatments that destroy vegetative cells, and then go on to germinate to form the vegetative cells that are associated with toxin production. The …

Oil palm residue biodelignification by bacillus cereus ligninase from coptotermus curvignathus gut for handsheet production
… with declined wood fibres. In this study, Bacillus cereus isolated from termite species Coptotermes curvignathus gut’s bacteria was tested for biodelignification capability on palm oil biomasses: oil palm leaves (OPL), oil palm trunk (OPT) and empty fruit bunch (EFB). The biopulp was …

Molecular analyses of YhcN/YlaJ and spore-associated proteins involved in germination of Bacillus cereus spores
… kill their vegetative cellular counterparts. Bacillus cereus is one such spore-forming organism, and is a significant vector in food-borne toxigenesis. The spore form of the organism is important in surviving food processing procedures, but germination and subsequent formation of a new …

Effects of high hydrostatic pressure processing on Bacillus cereus spores in fresh blue crab meat (Callinectes sapidus)
… products. One of the concerns is the presence of Bacillus cereus in fresh blue crab meat. Bacillus cereus is a spore-forming pathogen whose spores survive the customary thermal treatments applied during cooking and pasteurization; therefore it could potentially present a health concern to …

An Intracellular Polysaccharide that Serves as a Carbon and Energy Source for Sporulation in "Bacillus Cereus" Strain T
The Problem. "Bacillus cereus" strain T accumulates an intracellular polysaccharide during late logarithmic and early stationary phases of the growth cycle. The polysaccharide is subsequently degraded during the sporulation phase of the growth cycle. Initial research suggested that the …

Fatores de virulência de Bacillus cereus isolado na cadeia produtiva do leite na microrregião de Viçosa, Minas Gerais
A ocorrência de Bacillus cereus na cadeia produtiva do leite cru e de fatores de virulência associados a intoxicação diarréica foi avaliada em dois sistema de produção, um tecnificado e outro, não. Inicialmente o isolamento do micro-organismo foi feito no meio seletivo MYP (Manitol-Egg …
