Partial 16S rRNA gene sequences (16S rDNA) of Gemella morbillorum and Gemella haemolysans were determined by sequencing polymerase chain reaction-amplified DNA. A phylogenetic analysis of 53 eubacterial 16S rRNA sequences grouped the gemellae on a distinct branch separate from the 18 members of the genus Streptococcus. DNA-DNA hybridization results indicate that the two gemellae are related at the genus level but are not a single species.
通过对聚合酶链反应扩增的 DNA 进行测序，确定了麻疹孪生球菌和溶血孪生球菌的部分 16S rRNA 基因序列（16S rDNA）。对 53 种真细菌 16S rRNA 序列进行的系统发育分析将孪生球菌归为一个与链球菌属的 18 个成员不同的独立分支。DNA-DNA 杂交结果表明，这两种孪生球菌在属水平上相关，但不是单一物种。
