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-C17 : 0, anteiso-C15 : 0 and iso-C15 : 0. In view of phenotypical and biochemical characteristics as well as gene sequencing, strain A1336T 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 A1336T (=DSM 100333T =CCUG 67421T =CCOS 902T).

Studies have confirmed that insomnia is related to gut microbiota. Previous research suggests that immunity and metabolism are also associated with insomnia. However, to our knowledge, the integration of these factors has not been investigated in insomnia.
