Veillonella are Gram-negative bacteria (Gram stain pink) anaerobic cocci, unlike most Bacillota, which are Gram-positive bacteria.[1] This bacterium is well known for its lactate fermenting abilities. It is a normal bacterium in the intestines and oral mucosa of mammals. In humans they have been implicated in cases of osteomyelitis and endocarditis, for example with the species Veillonella parvula.
Veillonella dispar is the most nitrate-reducing bacterium in the oral cavity, which is beneficially anti-bacterial.[2]
When Veillonella is responsible for clinical infections in humans, it should be kept in mind that more than 70% of the strains are resistant to penicillin, while more than 95% of the strains are susceptible to amoxicillin/clavulanate.[3]
Fermentation
Lactate is fermented to propionate and acetate by the methylmalonyl-CoA pathway. Little ATP is produced in this fermentation. High substrate affinity is suggested to be the reason.
3 Lactate → acetate + 2 propionate + CO2+ H2O
A study of Veillonella in endurance athletes found that a relative abundance of the bacteria in the gut is associated with increased treadmill run time performance. This effect was demonstrated to be due to the organism's propionate metabolite produced from lactic acid.[4]
