Clinical strains of Acinetobacter classified by DNA‐DNA hybridization
Ingela Tjernberg,Jan Ursing +1 more
TL;DR: A collection of Acinetobacter strains consisting of 168 consecutive clinical strains and 30 type and reference strains was studied by DNA‐DNA hybridization and a few phenotypic tests, finding that hemolytic activity of this species has previously been regarded as non‐hemolytic.
Journal ArticleDOI
Characterization ofYersinia enterocolitica sensu stricto
H. Bercovier,Don J. Brenner,Jan Ursing,Arnold G. Steigerwalt,G. Richard Fanning,Jean Michel Alonso,Geraldine P. Carter,H. H. Mollaret +7 more
TL;DR: The speciesYersinia enterocolitica is definedsensu stricto on the bases of biochemical and other phenotypic characteristics, and was separable biochemically and by DNA relatedness from the two newly proposed rhamnose-positive species, yersinia intermedia and Yersinia frederiksenii.
Journal ArticleDOI
Yersinia frederiksenii: A new species of enterobacteriaceae composed of rhamnose-positive strains (formerly called atypicalyersinia enterocolitica orYersinia enterocolitica-Like)
Jan Ursing,J. Don Brennert,H. Bercovier,G. Richard Fanning,Arnold G. Steigerwalt,Jacqueline Brault,H. H. Mollaret +6 more
TL;DR: Yersinia kristensenii sp.
Journal ArticleDOI
Taxonomic Note: A Pragmatic Approach to the Nomenclature of Phenotypically Similar Genomic Groups
TL;DR: Sometimes, genomic groups (DNA groups, genomic species) that have been delimited by DNA-DNA pairing may be phenotypically so similar that they cannot be differentiated for the time being and to refer to genomic groups of a nomenspecies as genomovars.
Journal ArticleDOI
Genotypic and phenotypic diversity of pseudomonas stutzeri
TL;DR: There is still no sound basis for division of P. stutzeri at the species level, and it is proposed that the term ‘genomovar’ be used to denote genomic groups of a nomenspecies.
