Phylogenetic tree illustrates that CA16 clusters with strains of A. calcoaceticus. The accession numbers for non-type strains are from the NCBI. DDH values are between the indicated strain and CA16. Strains with the same color in the “cluster” column are predicted to be of the same species based on a DDH value of ≥70%. The tree was inferred with FastME 2.1.6.1 from the GBDP distances calculated based on their genome sequences. The branch lengths are scaled in terms of GBDP distance formula d5. The numbers above branches are GBDP pseudo-bootstrap support values > 60% from 100 replications, with an average branch support of 68.2%. The tree was trimmed to include only the Acb complex species with Acinetobacter brisouii as the outgroup
