context_page_description: The Salivary microbiome is the nonpathogenic, commensal bacteria present in the healthy human salivary glands. It is distinct from bacteria that may cause infection in the glands. It differs from the oral microbiome which is located in the oral cavity. Oral microorganisms tend to adhere to teeth. The oral microbiome possesses its own characteristic microorganisms found there. Resident microbes of the mouth adhere to the teeth and gums. "[T]here may be important interactions between the saliva microbiome and other microbiomes in the human body, in particular, that of the intestinal tract."
context_section_description: Organisms of the salivary microbiome reside in the three major salivary glands: parotid, submandibular, and sublingual. These glands secrete electrolytes, proteins, genetic material, polysaccharides, and other molecules. Most of these substances enter the salivary gland acinus and duct system from surrounding capillaries via the intervening tissue fluid, although some substances are produced within the glands themselves. The level of each salivary component varies considerably depending on the health status of the individual and the presence of pathogenic and commensal organisms.
