Unlike the uterine, placental and vaginal microbiomes, the types of organisms in the salivary microbiota remain relatively constant. There is no difference between populations of microbes of based upon gender, age, diet, obesity, alcohol intake, race, or tobacco use.[3] Porphyromonas, Solobacterium, Haemophilus, Corynebacterium, Cellulosimicrobium, Streptococcus and Campylobacter are some of the genera found in the saliva.[4]
