Genome-based reclassification of as a later heterotypic synonym of .

The present study used whole-genome data to clarify the taxonomic assignment of two closely related species. Genomic information for 10 type strains was available at the time of conducting this analysis. One group of type strains was found to be conspecific, namely Kämpfer . 1999 and Pathom-aree . 2006. The 16S rRNA gene sequences showed 99 % similarity between these type strains. Whole-genome-based comparisons showed that DSM 44343 and DSM 44944 shared 98.07 % average nucleotide identity, 98.29 % average amino acid identity and 84.80 % digital DNA-DNA hybridization values. These values exceeded the threshold values for bacterial species delineation. Further, phylogenomic analysis based on the core genomes of the strains under study confirmed that DSM 44343 and DSM 44944 formed a monophyletic clade. Based on this evidence, we propose the reclassification of Pathom-aree . 2006 as a later heterotypic synonym of Kämpfer . 1999.
