Species
Veillonella parvula
- Strain:Veillonella parvula DSM 2008
Description and significance
V. parvula is one of the six species belonging to the genus Veillonella which are gram-negative cocci and obligate anaerobes lacking capsule, spore or flagella [1]. This pathogen has been isolated from the periodontal pocket and has a role in dental plaque biofilm formation in the human oral cavity. V. parvula requires lactate as a nutrient source so it is commonly found in association with lactic-acid-producing species thus contributing to the cause of dental caries. Therefore it is established as the predominant species in subjects that have poor oral hygiene compared to those with moderate or good hygiene [1]. Moreover, it is found in the subgingival biofilm of patients with chronic periodontitis [2].
