Bacillus ciccensis and Cytobacillus solani were reported to belong to separate genomic species based on a polyphasic taxonomic approach. However, we found that type strains of B. ciccensis and C. solani should belong to the same genomic species based on the clustering patterns resulting from genome phylogenetic analysis. The average nucleotide identity and digital DNA-DNA hybridization values between the genomes of two type strains were 99.6% and 96.9%, respectively, much higher than 95 ~ 96% and 70% cut-off point proposed and generally accepted species boundary. This result was also supported by a comprehensive comparison of phenotypic characteristics between the two type strains. These results suggested that B. ciccensis and C. solani had the same taxonomic position. Consequently, we propose that B. ciccensis is a later heterotypic synonym of C. solani.

Bacillus ciccensis Liu 等人的提议。作为 Cytobacillus solani (Liu et al.) Patel 和 Gupta 使用比较基因组分析的后期异型同义词

据报道，根据多相分类方法，Bacillus ciccensis 和 Cytobacillus solani 属于不同的基因组物种。然而，根据基因组系统发育分析得出的聚类模式，我们发现 B. ciccensis 和 C. solani 的类型菌株应该属于同一基因组物种。两种类型菌株基因组之间的平均核苷酸同一性和数字DNA-DNA杂交值分别为99.6%和96.9%，远高于提出和普遍接受的物种界线的95~96%和70%分界点。这一结果也得到了两种类型菌株之间表型特征的综合比较的支持。这些结果表明 B. ciccensis 和 C. solani 具有相同的分类地位。因此，我们建议 B. ciccensis 是 C. ciccensis 的后来异型同义词。
