title: Characterisation of atypical biotype 3, serotype O:3 Yersinia and development of a simple identification scheme.
abstract: Five clinical strains of Yersinia isolated in Japan and identified as atypical biotype 3 or biotype 3B, serotype O:3, phage type II (3*/O:3/II) Yersinia enterocolitica were characterised since the biochemical reactions of these strains indicate they might also belong to the species Yersinia bercovieri. Biochemical tests, characterisation of the beta-lactamases and DNA-DNA hybridization studies provided strong evidence indicating that these strains should be classified as Yersinia enterocolitica. A simple scheme combining a disc diffusion test and four biochemical tests was devised for identification of these atypical strains.
