Ochrobactrum anthropi ATCC 49188T and Ochrobactrum lupini LUP21T are strains isolated from human clinical and plant root nodule samples, respectively, which share high similarity for phylogenetic markers (i.e 100 % for 16S rRNA, 99.9 % for dnaK and 99.35 % for rpoB). In this work, multiple genome average nucleotide identity (ANI) approaches, digital DNA–DNA hybridization (dDDH) and phylogenetic analysis were performed in order to investigate the taxonomic relationship between O. anthropi ATCC 49188T, O. lupini LUP21T, and other five type strains from the genus Ochrobactrum . Whole-genome comparisons demonstrated that O. lupini LUP21T and the Ochrobactrum genus type species, O. anthropi ATCC 49188T, share 97.55 % of ANIb, 98.25 % of ANIm, 97.99 % of gANI, 97.94 % of OrthoANI and 83.9 % of dDDH, which exceed the species delineation thresholds. These strains are also closely related in phylogenies reconstructed from a concatenation of 1193 sequences from single-copy ortholog genes. A review of their profiles revealed that O. anthropi ATCC 49188T and O. lupini LUP21T do not present pronounced differences at phenotypic and chemotaxonomic levels. Considering phylogenetic, genomic, phenotypic and chemotaxonomic data, O. lupini should be considered a later heterotypic synonym of O. anthropi .", }
