Query: NC_009674:2551759 Bacillus cytotoxicus NVH 391-98 chromosome, complete genome Lineage: Bacillus cytotoxicus; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria General Information: Isolated from a food poisoning outbreak in a nursing home for elderly people in France in March 1998. Under starvation conditions this group of bacteria initiate a pathway that leads to endospore formation, a process that is thoroughly studied and is a model system for prokaryotic development and differentiation. Spores are highly resistant to heat, cold, dessication, radiation, and disinfectants, and enable the organism to persist in otherwise inhospitable environments. Under more inviting conditions the spores germinate to produce vegetative cells. Bacillus cytotoxicus is a member of the Bacillus cereus group, which represents sporulating soil bacteria containing pathogenic strains which may cause food poisoning outbreaks.

General Information: This strain was isolated from commercial yogurt in 1974 in the United Kingdom. Lactic acid producing bacterium used in cheese and yogert production. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes. Serologic grouping is based on antigenic differences in cell wall carbohydrates, in cell wall pili-associated protein, and in the polysaccharide capsule in group B streptococci. This organism is a lactic acid bacteria often used as a starter culture for fermented dairy products including yogurt and cheese.
