The genus comprises 261 species (at March 2020) that are extremely diverse at phenotypic, ecological and genotypic levels. This study evaluated the taxonomy of and on the basis of whole genome sequences. Parameters that were evaluated included core genome phylogeny, (conserved) pairwise average amino acid identity, clade-specific signature genes, physiological criteria and the ecology of the organisms. Based on this polyphasic approach, we propose reclassification of the genus into 25 genera including the emended genus , which includes host-adapted organisms that have been referred to as the group, and 23 novel genera for which the names , , , , , , , , , , , , , , , , , , , , , and are proposed. We also propose to emend the description of the family to include all genera that were previously included in families and . The generic term 'lactobacilli' will remain useful to designate all organisms that were classified as until 2020. This reclassification reflects the phylogenetic position of the micro-organisms, and groups lactobacilli into robust clades with shared ecological and metabolic properties, as exemplified for the emended genus encompassing species adapted to vertebrates (such as , , , , and ) or invertebrates (such as and ).
包含 261 个物种（截至 2020 年 3 月），在表型、生态和基因型水平上具有极高的多样性。本研究基于全基因组序列评估了 和 的分类学。评估的参数包括核心基因组系统发育、（保守）成对平均氨基酸同一性、类群特异性特征基因、生理标准和生物体的生态学。基于这种多相方法，我们建议将属重新分类为 25 个属，包括经过修正的属 ，其中包括被称为 组的宿主适应性生物体，以及 23 个新属，它们的名称分别为 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 ， 。我们还建议对科的描述进行修正，以包括以前包含在科 和 中的所有属。通用术语“乳杆菌”将继续用于指定所有被归类为 2020 年之前的微生物。这种重新分类反映了微生物的系统发育位置，并将乳杆菌分为具有共同生态和代谢特性的稳健进化枝，例如经过修正的属 ，它包含适应脊椎动物（如 、 、 、 和 ）或无脊椎动物（如 和 ）的物种。
