JF International Journal of Systematic and Evolutionary Microbiology, VO 65 IS Pt_10 SP 3674 OP 3682 DO https://doi.org/10.1099/ijsem.0.000473 PB Microbiology Society, SN 1466-5034, AB The phenotypic and genotypic characteristics of four Bordetella hinzii-like strains from human respiratory specimens and representing nrdA gene sequence based genogroups 3, 14 and 15 were examined. In a 16S rRNA gene sequence based phylogenetic tree, the four strains consistently formed a single coherent lineage but their assignment to the genus Bordetella was equivocal. The respiratory quinone, polar lipid and fatty acid profiles generally conformed to those of species of the genus Bordetella and were characterized by the presence of ubiquinone 8, of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and several aminolipids, and of high percentages of C16 : 0, cyclo-C17 : 0 and summed feature 2, as major chemotaxonomic marker molecules, respectively. The DNA G+C content was about 66 mol%, which corresponded with that of the high-percentage DNA G+C content genera of the family Alcaligenaceae including the genus Bordetella. DNA–DNA hybridization experiments revealed the presence of three distinct genomospecies and thus confirmed phenotypic differences as revealed by means of extensive biochemical characterization. We therefore propose to formally classify Bordetella genogroups 3, 14 and 15 as Bordetella bronchialis sp. nov. (type strain LMG 28640T = AU3182T = CCUG 56828T), Bordetella sputigena sp. nov. (type strain LMG 28641T = CCUG 56478T) and Bordetella flabilis sp. nov. (type strain LMG 28642T = AU10664T = CCUG 56827T). In addition, we propose to reclassify Achromobacter sediminum into the novel genus Verticia, as Verticia sediminum, gen. nov., comb. nov., on the basis of its unique phylogenetic position, its marine origin and its distinctive phenotypic, fatty acid and polar lipid profile., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000473
