Prevotella colorans sp nov., isolated from a human wound

A strain of obligately anaerobic, Gram-stain-negative and non-spore-forming rod-shaped bacterium was isolated from a human wound and characterized both phenotypically and genotypically. The strain was moderately saccharolytic and proteolytic. Phylogenetic analysis was based on full-length 16S rRNA gene sequence analysis and revealed the strain to represent a member of the genus Prevotella, but to be different from the described species, with the closest relationship to Prevotella bergensis and Prevotella multisaccharivorax. The genomic DNA G+C content was 43.2 mol%. The most abundant cellular long-chain fatty acids were 3-OH iso-C-17:0, anteiso-C-15:0 and iso-C-15:0. In view of phenotypical and biochemical characteristics as well as gene sequencing, strain A1336(T) is considered to represent a novel species within the genus Prevotella, for which the name Prevotella colorans sp. nov. is proposed. The type strain is A1336(T) (= DSM 100333(T) = CCUG 67421(T) = CCOS 902(T)).
