Bacillus cereus and related species.
Bacillus cereus is a gram-positive aerobic or facultatively anaerobic spore-forming rod. It is a cause of food poisoning, which is frequently associated with the consumption of rice-based dishes. The organism produces an emetic or diarrheal syndrome induced by an emetic toxin and enterotoxin, respectively. Other toxins are produced during growth, including phospholipases, proteases, and hemolys...
متن کاملBacillus cereus-induced food-borne outbreaks in France, 2007 to 2014: epidemiology and genetic characterisation
The aim of this study was to identify and characterise Bacillus cereus from a unique national collection of 564 strains associated with 140 strong-evidence food-borne outbreaks (FBOs) occurring in France during 2007 to 2014. Starchy food and vegetables were the most frequent food vehicles identified; 747 of 911 human cases occurred in institutional catering contexts. Incubation period was signi...
متن کاملMolecular epidemiology of Bacillus cereus food poisoning.
OBJECTIVES To investigate the potential use of DNA techniques in epidemiological diagnosis of Bacillus cereus food poisoning. SUBJECTS Fifty six B. cereus isolates from milk were studied. DESIGN The 56 B. cereus isolates were characterised into enterotoxin positive (27 isolates) and enterotoxin negative (29 isolates) using reverse passive latex agglutination technique. SETTING Plasmid and...
متن کاملIncidence and characterization of Bacillus cereus isolates contaminating dairy products.
A total of 293 dairy products purchased from local markets were examined to determine the incidence of and characterize Bacillus cereus. Isolations were made on mannitol-egg yolk-polymyxin B agar medium and confirmed by several staining and biochemical tests. B. cereus occurred in 17% of fermented milks, 52% of ice creams, 35% of soft ice creams, 2% of pasteurized milks and pasteurized fruit- o...
متن کاملBacillus cereus Group Bacteriophage Flapjack Genome Sequence
The Bacillus cereus group bacteriophage Flapjack, a double-stranded DNA (dsDNA) Myoviridae isolate collected from soil collected in Washington, DC, is a member of cluster C3 and encodes an intramolecular chaperone-containing tail fiber protein previously found in Podoviridae and Siphoviridae but not annotated in the Myoviridae.
