Veillonella parvula is a strictly anaerobic, Gram-negative, coccus-shaped bacterium in the genus Veillonella.[2] It is a normal part of the oral flora but can be associated with diseases such as periodontitis and dental caries as well as various systemic infections, including meningitis and osteomyelitis.[3] It has also been isolated from women with bacterial vaginosis and has been associated with hypertension together with Campylobacter rectus and Prevotella melaninogenica.[4]

V. parvula is unable to feed on carbohydrates, but can feed on lactate provided by Streptococcus species also found in the oral cavity.[5] Specifically, Streptococcus mutans and V. parvula can form multispecies biofilms that lead to a lower susceptibility to antimicrobial treatments, resulting in periodontitis and dental caries.[6]
