The gene sequence for the circular chromosomes of twelves pecies of streptococci have been sequenced: Streptococcus pneumoniae, Streptococcus agalactiae 2603 V/R, Streptococcus mutans, Streptococcus thermophilus CNRZ1066, Streptococcus thermophilus LMG 18311, and Streptococcus pyogenes.

 Re: Would this really CURE BB? at Body Odor & Bad Breath Forum
People who suffer from chronic bad breath either lack, or have very low levels, of the normally predominant Streptococcus salivarius, and their tongues are inhabited by undesirable bacteria often responsible for bad breath....
salivarius appears to help digest protein and may assist in the breakdown of any incompletely digested proteins and their undesirable by-products left in the gut which can cause putrefication.
salivarius is classified as a facultative bacterium, which means that it can survive and grow in both anaerobic (without oxygen) and aerobic (with oxygen) environments, although its main effects take place in anaerobic conditions.
