| Abstract |
A Gram-stain-positive, coccus-shaped, non-motile bacterium, designated CF-49T, was isolated from the cloacal content of a snow finch, which was incidentally captured in a plateau pika burrow on the Qinghai-Tibet Plateau, PR China. Analysis of the 16S rRNA gene sequence showed that strain CF-49T was closely related to Vagococcus elongatus CCUG 51432T (96.5 % similarity), Vagococcus fluvialis NCFB 2497T (96.0 %) and Vagococcus lutrae CCUG 39187T (95.9 %), whereas the similarity to another isolate (CF-210) was 99.9 %. Strains CF-49T and CF-210 grew optimally at 37 °C and pH 7.0 and in the presence of 0.5 % (w/v) NaCl. Acid was produced from N-acetylglucosamine, cellobiose, d-fructose, d-glucose, d-mannose, d-mannitol, maltose, d-ribose and salicin. The cell-wall peptidoglycan type was A4α (l-Lys-d-Asp). The major cellular fatty acids (>10 %) were C16 : 0 (35.6 %), C14 : 0 (17.3 %), C18 : 1 ω9c (16.2 %) and C16 : 1 ω9c (10.6 %). The predominant respiratory quinone was menaquinone MK-7 (68.8 %). The G+C content of the genomic DNA was 35.9 mol%. Digital DNA-DNA hybridization of strain CF-49T with V. fluvialis DSM 5731T, V. elongatus CCUG 51432Tand V. lutrae CCUG 39187T resulted in relatedness values of 21.4, 23.3 and 24.6 %, respectively. Based on results from polyphasic analyses, our two isolates are proposed to represent a novel species in the genus Vagococcus, with the name Vagococcus xieshaowenii. The type strain is CF-49T (=CGMCC 1.6436T=GDMCC 1.1588T=JCM 33477T).
