Genome-based reclassification of Chhetri . 2023 as a later heterotypic synonym of Gao . 2023 No Access

Abstract

DHUNG17 was compared with XHP0097 to examine the taxonomic relationship between the two type strains. The 16S rRNA gene sequence of DHUNG17 shared high similarity (99.9 %) to that of XHP0097. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus . The average amino acid identity, average nucleotide identity and digital DNA–DNA hybridization values between DHUNG17 and XHP0097 were below 99.0, 99.1 and 92.2±1.7 %, respectively, all of which were greater than the species delineation threshold for AAI (95.5 %), ANI (95–96 %) and dDDH (70 %), strongly indicating that the two strains represented a single species. Based on the combined phylogenetic, genomic and phenotypic characterization presented here, we propose as a later heterotypic synonym of .
