Very nice strains! There was a lady in, I believe Latin-America, who had terrible oral hygiene and yet never had a cavity. So they analyzed her saliva and found this specific strain. I just spent 30 minutes looking for the study that I'm referring to but I can't find it for the life of me, apologies for that. I believe it was one of the streptococcus salivarius strains that you already included though :)
