( 2008 ) Naxibacter varians sp. nov. and Naxibacter haematophilus sp. nov., and emended description of the genus Naxibacter. PMID : 18599716 DOI : 10.1099/ijs.0.65516-0 Abstract >>
Six Gram-negative, rod-shaped, non-spore-forming bacteria isolated from clinical specimens and water samples were investigated for their taxonomic allocation. On the basis of 16S rRNA gene sequence similarities, these strains (CCUG 35299(T), CCUG 24677A, CCUG 48018, CCUG 49054, CCUG 48700A and CCUG 38318(T)) were shown to belong to the Betaproteobacteria, closely related to Naxibacter alkalitolerans (97.9-98.8 % sequence similarity to the type strain). Chemotaxonomic data (major ubiquinone Q-8; major polyamines hydroxyputrescine and putrescine; major polar lipids phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol; major fatty acids C(16 : 1)omega7c and C(16 : 0), with 3-OH C(10 : 0) and 2-OH C(12 : 0) as hydroxylated fatty acids) supported the affiliation of the isolates to the genus Naxibacter. The results of DNA-DNA hybridization and physiological and biochemical tests allowed both genotypic and phenotypic differentiation of the isolates from the described Naxibacter species. Isolates CCUG 35299(T), CCUG 24677A, CCUG 48018, CCUG 49054 and CCUG 48700A were closely related on the basis of DNA-DNA reassociation experiments and therefore represent a single novel species, for which the name Naxibacter varians sp. nov. is proposed, with the type strain CCUG 35299(T) (=CCM 7478(T)). Strain CCUG 38318(T) represents a second novel Naxibacter species, for which we propose the name Naxibacter haematophilus sp. nov. (type strain CCUG 38318(T) =CCM 7480(T)).

( 2011 ) Revision of the genus Massilia La Scola et al. 2000, with an emended description of the genus and inclusion of all species of the genus Naxibacter as new combinations, and proposal of Massilia consociata sp. nov. PMID : 20656816 DOI : 10.1099/ijs.0.025585-0 Abstract >>
A Gram-stain-negative, rod-shaped, non-spore-forming bacterium originating from a human clinical specimen was studied for its taxonomic position. 16S rRNA gene sequence similarity studies clearly allocated this strain (CCUG 58010(T)) to the class Betaproteobacteria, closely related to members of the genera Massilia and Naxibacter. Naxibacter varians was shown to be the most closely related species on the basis of 16S rRNA gene sequence similarity (97.5 %), followed by Massilia niastensis (96.8 %) and Massilia aerilata (96.4 %). Similarities to all other species of the genera Naxibacter and Massilia were in the range 93.9-96.2 %. Chemotaxonomic data (major ubiquinone: Q-8; major polar lipids: phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol; and major fatty acids: summed feature 3 (C(16 : 1)�s7c and/or iso-C(15 : 0) 2-OH), C(16 : 0), C(18 : 1)�s7c and C(12 : 0), with C(10 : 0) 3-OH as hydroxylated fatty acid) supported the affiliation of the isolate to these genera, which share these chemotaxonomic traits. DNA-DNA hybridization of strain CCUG 58010(T) with the type strain of N. varians CCUG 35299(T) resulted in a relatedness value of 39.2 % (reciprocal, 50 %) and physiological and biochemical tests also allowed phenotypic differentiation of the isolate from the most closely related species. There is currently no justification for a division of the genera Massilia and Naxibacter and for this reason a proposal is made to transfer all species of the genus Naxibacter to the genus Massilia, as Massilia alkalitolerans comb. nov., Massilia varians comb. nov., Massilia haematophila comb. nov. and Massilia suwonensis comb. nov. Strain CCUG 58010(T) represents a novel species, for which the name Massilia consociata sp. nov. is proposed, with the type strain CCUG 58010(T) (= CCM 7792(T)).
