Summarising the pairwise ANI, AAI and estimated DDH values of the S. somaliensis and S. sudanensis type strain genomes compared to genomes in GTDB.

Species thresholds are usually defined by ANI >95%, AAI >95% and DDH >70%. Values that fall below these thresholds are highlighted in grey. Results indicate that GTDB GCF_000258695 (annotated as S. somaliensis) is most closely related to S. sudanensis, though it is a different species.物种分类阈值通常以平均核苷酸同一性（Average Nucleotide Identity, ANI）>95%、平均氨基酸同一性（Average Amino Acid Identity, AAI）>95%以及DNA-DNA杂交（DNA-DNA Hybridization, DDH）>70%作为判定标准。低于上述阈值的数值将以灰色高亮显示。分析结果表明，基因组分类数据库（Genome Taxonomy Database, GTDB）中注释为S. somaliensis的GCF_000258695与S. sudanensis亲缘关系最近，尽管二者属于不同的物种。
