taxonomic characterization of ochrobactrum sp. isolates from soil samples and wheat roots, and description of ochrobactrum tritici sp. nov. and ochrobactrum grignonense sp. nov.a large collection of bacterial strains, immunotrapped from soil and from the wheat rhizoplane, was subjected to polyphasic taxonomy by examining various pheno- and genotypic parameters. strains were grouped on (inter) repetitive extragenic palindromic dna (rep) pcr profiles at the intraspecies level. pheno- and genotypic characters were assessed for representatives from 13 different rep groups. strains of nine rep groups constituting two physiological biolog clusters fell in the coherent dna-dn ...200011155998
towards a standardized format for the description of a novel species (of an established genus): ochrobactrum gallinifaecis sp. nov.a format for the description of single novel species is proposed, which should facilitate the reviewing process by assisting the provision of data in a standardized form. the abstract must be short and concise, highlighting phylogenetic position, morphology and chemotaxonomy for genus affiliation, the genotypic and phenotypic basis for species differentiation, and the name and deposition numbers from two public culture collections in different countries for the type strain: a gram-negative, rod- ...200312807218
pulsed-field gel electrophoresis to study the diversity of whole-genome organization in the genus ochrobactrum.the alpha-proteobacterial genus ochrobactrum groups together organisms that display varied life-styles, such as free-living bacteria, members of rhizosphere and soil, nitrogen-fixing bacteria in plant nodules, xenobiotic-degrading bacteria, colonizers of nematodes and insects, and opportunistic human pathogens. the genomes of nine strains of ochrobactrum anthropi and eight strains of ochrobactrum intermedium were analyzed by pulsed-field gel electrophoresis of the whole genome and of i-ceui dige ...200515995979
genetic and phenotypic microdiversity of ochrobactrum spp.the diversity of ochrobactrum anthropi, ochrobactrum intermedium, ochrobactrum tritici and ochrobactrum grignonense in agricultural soil and on the wheat rhizoplane was investigated. o. anthropi was isolated both from soil and from the rhizoplane, o. intermedium and grignonense only from bulk soil, and o. tritici only from the wheat rhizoplane. on the genetic level, the immunotrapped isolates and a number of strains from culture collection mainly of clinical origin were compared with rep-pcr pro ...200616629756
ochrobactrum haematophilum sp. nov. and ochrobactrum pseudogrignonense sp. nov., isolated from human clinical specimens.three gram-negative, rod-shaped, non-spore-forming bacteria were isolated from clinical specimens between 1992 and 2000. on the basis of 16s rrna gene sequence similarities, these strains (ccug 30717t, ccug 43892 and ccug 38531t) were shown to belong to the alphaproteobacteria, most closely related to ochrobactrum grignonense (99.0 and 98.2% similarity to the type strain). chemotaxonomic data (major ubiquinone q-10; major polyamines spermidine, sym-homospermidine and putrescine; major polar lipi ...200717978211
ochrobactrum pituitosum sp. nov., isolated from an industrial environment.strain ccug 50899, a gram-negative, rod-shaped, non-spore-forming, motile bacterium isolated from industrial environment in sweden and tentatively assigned to the species ochrobactrum anthropi, was studied in order to clarify its taxonomic status. 16s rrna gene sequence similarities placed the strain in the genus ochrobactrum, sharing highest similarity with the type strains of ochrobactrum rhizosphaerae (99.3 %), ochrobactrum thiophenivorans (98.7 %), ochrobactrum pseudogrignonense (98.6 %) and ...201019651740
