Two groups of previously undescribed anaerobic, gram-positive cocci recovered from human clinical infections were characterized using phenotypic and molecular genotypic methods. Comparative genotypic analysis showed that the strains within each of these two groups were homogeneous within the group and that each group was unique within the genus Peptoniphilus. The first group is most closely related to Peptoniphilus ivorii and the second group to Peptoniphilus harei. Based on these findings we propose two novel species, Peptoniphilus coxii sp. nov. and Peptoniphilus tyrrelliae sp. nov. The type strains are P. coxii sp. nov., RMA 16757(T) (= JCM 16892(T) = CCUG 59622(T) = ATCC BAA-2106(T)) and P. tyrrelliae sp. nov., RMA 19911(T) (= JCM 16893(T) = CCUG 59621(T) = ATCC BAA-2105(T)).
两组先前未被描述的来自人类临床感染的厌氧、革兰阳性球菌，使用表型和分子基因分型方法进行了特征描述。比较基因分析表明，这两组内的菌株在组内是同质的，并且每组在消化链球菌属内都是独特的。第一组与伊沃氏消化链球菌最为密切相关，第二组与哈雷氏消化链球菌最为密切相关。基于这些发现，我们提出了两个新种，即考克斯氏消化链球菌（Peptoniphilus coxii）sp. nov. 和泰氏消化链球菌（Peptoniphilus tyrrelliae）sp. nov.。模式菌株为 Coxi 氏消化链球菌（Peptoniphilus coxii）sp. nov.，RMA 16757（T）（=JCM 16892（T）=CCUG 59622（T）=ATCC BAA-2106（T））和泰氏消化链球菌（Peptoniphilus tyrrelliae）sp. nov.，RMA 19911（T）（=JCM 16893（T）=CCUG 59621（T）=ATCC BAA-2105（T））。
