Abstract

A Gram-stain-negative, motile, non-spore-forming, coccoid bacterium was isolated from a stool sample of a healthy human subject and formed cream colour colonies on tryptic soy agar. Almost full-length (1500 bp) small subunit rRNA (16S rRNA) gene sequences were generated and a similarity search was conducted by blast. The results of the similarity search indicated that the bacterium belongs to the class Betaproteobacteria, family Alcaligenaceae. It showed maximum sequence similarity (96.5 %) with Pelistega europaea CCUG 39967(T) followed by Advenella mimigardefordensis DSM 17166(T) (96.1 %) and Taylorella asinigenitalis LMG 19572(T) (95.3 %). The DNA G+C content of strain HM-7(T) was 42 mol%. Strain HM-7(T) contained C14 : 0, C16 : 0, C16 : 0 3-OH and C18 : 0 as the dominant fatty acids. Morphological, physiological and biochemical data also indicated that strain HM-7(T) represents a member of the genus Pelistega, but at the same time distinguished it from Pelistega europaea CCUG 39967(T), the only species of the genus with a validly published name. Based on polyphasic characterization we conclude that the bacterium represents a novel species of the genus Pelistega and propose the name Pelistega indica sp. nov., with strain HM-7(T) ( = MCC 2185(T) = DSM 27484(T)) as the type strain of the species.
