species of spherical, gram-positive bacteria Streptococci (from phylum Firmicutes) that forms chains and colonizes the mouth and upper respiratory tract of humans just a few hours after birth, making further exposure to the bacteria harmless in most circumstances. It is considered to be a "good" oral bacteria fighting bad odor and disease-causing species yet, if it gets into bloodstream (what, fortunately, rarely happens), it could be associated with sepsis in people with neutropenia (a deficiency in white blood cells). Streptococcus salivarius secretes a glucosltransferase (Gtf) which forms a glucan from sucrose and it uses sucrose (but not glucose) to build a capsule around itself. This bacteria can ferment the glucose yielding lactic acid. S. salivarius is also known to secrete an enzyme called urease. Urease can catalyze the hydrolysis of urea to ammonia and carbon dioxide
S. salivarius is a pioneer colonizer of the human oral cavity and lives there as a most prevalent member of the native microbiota throughout the life of its human host. In saliva, it is typically present at levels of up to 1 × 107 colony forming units (cfu)/ml. Strain K12 used in probiotic Blis K12 was originally introduced to counter Streptococcus pyogenes infections, ranging from mild superficial skin infections to life-threatening systemic diseases. It is now used to control many other bacterial infections including ear infections, oral Candida albicans infection, bad breath, and tooth cavities.
