通过16S核糖体DNA(RDNA)序列测定，发现除红粘葡萄球菌外，该属的5个种(红粘葡萄球菌、蛋白溶解葡萄球菌、耐辐射性葡萄球菌、嗜辐射性葡萄球菌和放射性葡萄球菌)和单种嗜血杆菌(巨型葡萄球菌)的16S核糖体DNA(RDNA)序列是一致的。对其16S rDNA序列的分析表明，该菌是一种放线菌，属于Kacuria属，大变形杆菌属于Kacuria属，在系统发育上可以认为是该属的一个成员。系统发育分析的结果与化学分类学的结果是一致的。根据我们的资料，该属的描述相应地被修改为Deinodicus属，并将其命名为Kocuria red myxcomb，nov.并将一组16S rDNA特征核苷酸命名为该群，根据其独特的系统发育位置和一组16S rDNA特征核苷酸，描述了新目--新球菌目。
16S ribosomal DNA (rDNA) sequences were determined for the five species of the genus Deinococcus (Deinococcus erythromyxa, Deinococcus proteolyticus, Deinococcus radiodurans, Deinococcus radiophilus, and Deinococcus radiopugnans) and the single species of the genus Deinobacter (Deinobacter grandis), With the exception of Deinococcus erythromyxa, the deinococci form a coherent phylogenetic cluster which is related to the Thermus-Meiothermus lineage. An analysis of the 16S rDNA sequence of Deinococcus erythromyxa revealed that this organism is an actinomycete and a member of the genus Kacuria, Deinobacter grandis falls within the radiation of the genus Deinococcus and phylogenetically can be considered a member of this genus, The results of the phylogenetic analyses are consistent with chemotaxonomic data, On the basis of our data, Deinobacter grandis is transferred to the genus Deinococcus as Deinococcus grandis comb, nov., the description of the genus Deinococcus is emended accordingly, and Deinococcus erythromyxa is transferred to the genus Kocuria as Kocuria erythromyxa comb, nov, The description of the family Deinococcaceae is emended to include organisms with rod-shaped cells, and a set of 16S rDNA signature nucleotides is designated for this group, On the basis of the distinct phylogenetic position of the Deinococcus lineage and a set of 16S rDNA signature nucleotides, the order Deinococcales ord, nov, is described.
