Veillonella is a genus of anaerobic, gram-negative bacteria that inhabit various parts of the human body, including the oral cavity, gastrointestinal tract, respiratory tract, and vagina. This genus is among the most prevalent and abundant bacterial groups found in the human gut microbiota, and recent research has revealed their potential roles in human health and disease.
Basics: Veillonella bacteria have unique metabolic capabilities that allow them to metabolize lactate, a byproduct of anaerobic glycolysis, as their primary energy source. This feature makes them a key player in the gut microbial ecosystem by enabling them to scavenge lactate produced by other gut bacteria, thereby reducing lactate accumulation, which can cause inflammation and gut dysbiosis. Veillonella bacteria also produce short-chain fatty acids (SCFAs), including propionate, which is known to have anti-inflammatory properties and regulate host metabolism.
Functions: Recent research has suggested that Veillonella bacteria have a number of important functions in human health, including:
Research: Recent studies have demonstrated the importance of Veillonella bacteria in human health and disease. In a study published in the journal Nature Medicine, researchers found that Veillonella bacteria were present in higher levels in the gut microbiota of elite athletes compared to sedentary individuals. Another study published in the journal Cell Host & Microbe found that Veillonella bacteria were associated with reduced risk of inflammatory bowel disease (IBD) in a mouse model.
How to boost Veillonella: There are several ways to boost the levels of Veillonella bacteria in the gut microbiota:
