Abstract

Lactococcus muris was published in Cell Host & Microbe in November 2022 and validated in validation list no. 213 in October 2023. Lactococcus intestinalis was published in Antonie van Leeuwenhoek in May 2023 and validated in validation list no. 216 in March 2024. Both of them were isolated from the mouse gut. Previous studies indicated that L. muris DSM 109779^T had the highest 16S rRNA gene sequence identity to Lactococcus garvieae (96.7%), and that L. intestinalis M2458^T had the highest 16S rRNA gene sequence similarities to Lactococcus formosensis NBRC 109475^T (97.6%) and L. garviae NBRC 100934^T (97.1%). However, the taxonomic relationship between L. muris and L. intestinalis has not yet been investigated and therefore is the focus of the present study. In the present study, the relationship between L. muris and L. intestinalis was evaluated. The type strains of L. muris and L. intestinalis shared 100% 16S rRNA gene sequence similarity, 100% pheS sequence similarity, 100% rpoA sequence similarity, 99.9% average nucleotide identity (ANI) value and 98.5% digital DNA-DNA hybridization (dDDH) value, indicating that they represented the same species. On the basis of the results present here, we propose L. intestinalis Sun et al. 2024 as a later heterotypic synonym of L. muris Afrizal et al. 2023.

无肠乳球菌Sun等人2024作为muris Afrizal等人的后异型同系物的提议。

乳酸菌于2022年11月发表在《细胞宿主与微生物》杂志上，并在第1号验证清单中得到验证。2023年10月。肠乳球菌于2023年5月发表于Antonie van Leeuwenhoek，并在验证清单no. 1中得到验证。2024年3月216号。它们都是从小鼠肠道中分离出来的。既往研究表明，L. muris DSM 109779T与garvieae乳球菌16S rRNA基因序列相似性最高（96.7%），L. n肠肠alis M2458T与台湾乳球菌NBRC 109475T（97.6%）和L. garviae NBRC 100934T (97.1%) 16S rRNA基因序列相似性最高。然而，鼠乳杆菌和肠乳杆菌的分类学关系尚未被研究，因此是本研究的重点。本研究对鼠乳杆菌和肠乳杆菌的关系进行了评价。鼠乳杆菌和肠乳杆菌类型菌株的16S rRNA基因序列相似性为100%，pheS序列相似性为100%，rpoA序列相似性为100%，平均核苷酸同源性（ANI）值为99.9%，数字DNA-DNA杂交（dDDH）值为98.5%，表明它们属于同一物种。在此基础上，我们提出L. ninteinalis Sun et al. 2024是L. muris Afrizal et al. 2023的后异型同义种。
