The 16S rRNA primary structures of Eubacterium suis DSM 20639T (T = type strain) and Bifidobacterium bifidum DSM 20456T were determined by sequencing in vitro amplified rDNA. Sequence comparisons indicated that B. bifidum is moderately related to representatives of the genera Actinomyces and Mobiluncus. The closest relative of E. suis is Actinomyces pyogenes. E. suis and A. pyogenes are more closely related phylogenetically to one another than to the other Actinomyces species that have been investigated by using comparative 16S rRNA analysis. Therefore, we propose that E. suis should be transferred to the genus Actinomyces as Actinomyces suis comb. nov.
通过对体外扩增的核糖体DNA进行测序,确定了猪优杆菌DSM 20639T(T = 模式菌株)和两歧双歧杆菌DSM 20456T的16S rRNA一级结构。序列比较表明,两歧双歧杆菌与放线菌属和动弯杆菌属的代表菌株有中等程度的相关性。猪优杆菌最接近的亲缘种是化脓放线菌。通过比较16S rRNA分析,猪优杆菌和化脓放线菌在系统发育上彼此之间的关系比与其他已研究的放线菌物种更为密切。因此,我们建议将猪优杆菌转移到放线菌属,命名为猪放线菌,新组合。
