ABSTRACT
Two strains of Gram-stain-positive, facultatively anaerobic, non-spore-forming short rods (VUL7T and VUL8) were isolated from rectal swabs of Old World vultures, namely Gyps himalayensis, in Tibet-Qinghai Plateau, China. Optimal growth occurred at 37 °C, pH 6-7, with 1â% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences classified the two strains to the genus Actinomyces, with highest 16S rRNA gene sequence similarity (95â%) to type strains of Actinomyces haliotis, Actinomyces radicidentis and Actinomyces urogenitalis. The major cellular fatty acids were C18ââ1ω9c and C16ââ0. MK-10(H4) was the major respiratory quinone. The genomic DNA G+C content of the isolate was 54.4 mol%. DNA-DNA hybridization values with the most closely related species ofthe genusActinomyces was 24.6â%. The two strains can be differentiated from the most closely related species such as A. haliotis, A. radicidentis, A. graevenitzii and A. urogenitalis by a list of carbohydrate fermentations and enzyme activities. On the basis of physiological, biochemical and phylogenetic analysis, strains VUL7T and VUL8 represent novel species of the genus Actinomyces, for which the name Actinomyces vulturis sp. nov. is proposed. The type strain is VUL7T (=CGMCC 4.7366T=DSM 103437T).
