A review on the characterization of a novel oral Veillonella species, V. Tobetsuensis, and its role in oral biofilm formation

摘要

The genus Veillonella consists of small, strictly anaerobic, gram-negative cocci that lack flagella, spores, and a capsule. Although 11 species have been established in the genus Veillonella, five species, namely V. atypica, V. denticariosi, V. dispar, V. parvula, and V. rogosae, are recognized as oral Veillonella. The main habitats of oral Veillonella are the tongue, dental biofilm, and the buccal mucosa, and correspondingly it has been suggested that oral Veillonella contributes to oral biofilm formation and may lead to the formation of dental disease such as periodontitis. Recently, unknown strains displaying all phenotypic characteristics of the genus Veillonella were isolated from human tongue biofilm. The production of a major cellular fatty acid (C13:0 and C17:1
