“…Though it is not a member of the mutans streptococci, Streptococcus salivarius is also associated with formation of dental caries (Becker et al, 2002). S. salivarius is one of the earliest colonisers of the oral cavity following birth (Carlsson, Grahnen, Jonsson, & Wikner, 1970), and has long been recognised as a 'potent acid producer' (Shiere, Georgi, & Ireland, 1951). In addition to causing dental caries, microorganisms inhabiting the oral cavity can be introduced into the bloodstream, leading to occurrence of 'focal oral infections', including bacteremia, endocarditis and meningitis (Gendron, Grenier, & Maheu-Robert, 2000;Reif, Roller, Rawling, & Granato, 2009).…”
