- The phenotypic and genotypic characteristics of fourteen human clinical Achromobacter strains representing four genogroups which were delineated by sequence analysis of nusA, eno, rpoB, gltB, lepA, nuoL and nrdA loci, demonstrated that they represent four novel Achromobacter species. The present study also characterized and provided two additional reference strains for Achromobacter ruhlandii and Achromobacter marplatensis, species for which, thus far, only single strains are publicly available, and further validated the use of 2.1% concatenated nusA, eno, rpoB, gltB, lepA, nuoL and nrdA sequence divergence as a threshold value for species delineation in this genus. Finally, although most Achromobacter species can be distinguished by biochemical characteristics, the present study also highlighted considerable phenotypic intraspecies variability and demonstrated that the type strains may be phenotypically poor representatives of the species. We propose to classify the fourteen human clinical strains as Achromobacter mucicolens sp. nov. (with strain LMG 26685(T) [=CCUG 61961(T)] as the type strain), Achromobacter animicus sp. nov. (with strain LMG 26690(T) [=CCUG 61966(T)] as the type strain), Achromobacter spiritinus sp. nov. (with strain LMG 26692(T) [=CCUG 61968(T)] as the type strain), and Achromobacter pulmonis sp. nov. (with strain LMG 26696(T) [=CCUG 61972(T)] as the type strain).

- The phenotypic and genotypic characteristics of seventeen Achromobacter strains representing MLST genogroups 2, 5, 7 and 14 were examined. Although genogroup 2 and 14 strains shared a DNA-DNA hybridization level of about 70%, the type strains of both genogroups differed in numerous biochemical characteristics and all genogroup 2 and 14 strains could by distinguished by nitrite reduction, denitrification and growth on acetamide. Given the MLST sequence divergence which identified genogroups 2 and 14 as clearly distinct populations, the availability of nrdA sequence analysis as a single locus identification tool for all Achromobacter species and genogroups, and the differential phenotypic characteristics, we propose to formally classify Achromobacter genogroups 2, 5, 7 and 14 as four novel Achromobacter species for which we propose the names Achromobacter insuavis sp. nov. (with strain LMG 26845(T) [=CCUG 62426(T)] as the type strain), Achromobacter aegrifaciens sp. nov. (with strain LMG 26852(T) [=CCUG 62438(T)] as the type strain), Achromobacter anxifer sp. nov. (with strain LMG 26857(T) [=CCUG 62444(T)] as the type strain), and Achromobacter dolens sp. nov. (with strain LMG 26840(T) [=CCUG 62421(T)] as the type strain).
