Interpretive Summary: This study clarifies the taxonomy of two bacterial strains. These two strains we erroneously described as separate species, but new research shows them to be the same species. Understanding the correct taxonomy and nomenclature of these strains improves the communication of ideas, prevents duplication of research and may have regulatory implications. Novel bacteria such as these may possess unique and unusual biochemical properties that make them attractive candidates to explore their potential for new uses in agriculture or biotechnology.

Technical Abstract: Acinetobacter lactucae and Acinetobacter dijkshoorniae were recently described as new species, in which both were reported to be closely related to Acinetobacter pittii. Because they were reviewed and published almost concurrently, their descriptions did not include a specific comparison between these species. Genomic data were provided in both initial descriptions and simplifies the comparisons. Genome comparisons based on in silico DNA-DNA hybridizations, average nucleotide identity and core genome phylogeny of the type strain genomes establish these strains are conspecific. Based on the rules of priority, A. dijkshoorniae should be reclassified as a later heterotypic synonym of A. lactucae.
