Query: NC_009785:1414892 Streptococcus gordonii str. Challis substr. CH1, complete genome

Lineage: Streptococcus gordonii; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria

General Information: Normal human oral flora. 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. Streptococcus gordonii is a commensal member of the human oral flora. It initiates the formation of biofilms on tooth surfaces known as dental plaque, which is strongly associated with the development of dental cavities (caries) and gum disease. It is a frequent causative agent of bacterial endocarditis (inflammation of the membrane lining the heart) which often occurs as a result of oral trauma, allowing S. gordonii to invade the bloodstream and colonize the heart.

Subject: NC_009513:1184000 Lactobacillus reuteri F275, complete genome

Lineage: Lactobacillus reuteri; Lactobacillus; Lactobacillaceae; Lactobacillales; Firmicutes; Bacteria

General Information: This strain (JCM 1112, F275) is the type strain for the species. It is a human isolate, which is unable to colonize the intestinal tract of mice. Normal gut bacterium. They are commonly found in the oral, vaginal, and intestinal tracts of many animals. They are important industrial microbes that contribute to the production of cheese, yogurt, and other products such as fermented milks, all stemming from the production of lactic acid, which inhibits the growth of other organisms as well as lowering the pH of the food product. Industrial production requires the use of starter cultures, which are carefully cultivated, created, and maintained. These cultures produce specific end products during fermentation that impart flavor to the final product, as well as contributing important metabolic reactions, such as the breakdown of milk proteins during cheese production. The end product of fermentation, lactic acid, is also used as a starter molecule for complex organic molecule syntheses. Lactobacillus reuteri is a member of the normal microbial community of the gut in humans and animals. This organism produces antibiotic compounds, such as reutericin and reuterin, which have inhibitory effects on pathogenic microorganisms.
