1. Normal Microbiota: Veillonellaceae bacteria, particularly Veillonella species, are commonly found in the oral cavity, gastrointestinal tract, and other mucosal surfaces. They are part of the normal microbial community in humans.

2. Oral Health: Veillonella species are often associated with the oral microbiota and can be found in dental plaque. While some species of Veillonella are considered commensal and part of the normal oral flora, their abundance and interactions with other bacteria can contribute to oral health or, in some cases, dental diseases.

3. Gut Microbiota: Veillonellaceae members are also present in the gut microbiota. They play a role in the complex microbial community of the digestive tract, contributing to fermentation processes and the production of metabolites.

4. Fermentation: Veillonella bacteria are known for their ability to ferment lactate. They participate in the conversion of lactate produced by other bacteria into end-products, such as short-chain fatty acids (SCFAs) like propionate. SCFAs have been associated with various health benefits, including anti-inflammatory effects and maintenance of gut barrier function.

5. Influence on Disease States: Changes in the abundance of Veillonellaceae, including Veillonella species, have been observed in different disease states. For example, alterations in the relative abundance of Veillonellaceae have been reported in individuals with inflammatory bowel diseases (IBD), such as Crohn's disease and ulcerative colitis. However, the specific role of Veillonellaceae in these conditions is complex and requires further investigation.

6. Dietary Influences: The abundance of Veillonellaceae in the gut microbiota may be influenced by dietary factors. Certain studies have suggested associations between the presence of Veillonellaceae and dietary patterns, including the consumption of specific nutrients.
