The species Yersinia (Y.) enterocolitica consists of biochemically and serologically heterogeneous strains. A vernacular nomenclature divides these strains in 'European' and 'American' bioserotypes. We investigated six strains of each group by DNA-DNA hybridization, determination of G + C mol% content and sequence alignment studies. Based on different DNA-DNA hybridization values and the 16S rRNA gene sequences a division into two Yersinia enterocolitica subspecies is justified. We propose the names Yersinia enterocolitica subsp. enterocolitica for strains belonging to the 16S rRNA gene type represented by the Type strain ATCC 9610 and Yersinia enterocolitica subsp. palearctica for strains belonging to the 16S rRNA gene type of strain Y11 (DSMZ13030).
小肠结肠炎耶尔森氏菌（Yersinia (Y.) enterocolitica）种由生化和血清学上异质的菌株组成。通俗的命名法将这些菌株分为“欧洲”和“美洲”生物血清型。我们通过DNA-DNA杂交、G + C摩尔%含量的测定以及序列比对研究，对每组的六个菌株进行了调查。基于不同的DNA-DNA杂交值和16S rRNA基因序列，将小肠结肠炎耶尔森氏菌分为两个亚种是合理的。我们建议将属于以模式菌株ATCC 9610为代表的16S rRNA基因类型的菌株命名为小肠结肠炎耶尔森氏菌小肠结肠炎亚种（Yersinia enterocolitica subsp. enterocolitica），将属于菌株Y11（DSMZ13030）的16S rRNA基因类型的菌株命名为小肠结肠炎耶尔森氏菌古北区亚种（Yersinia enterocolitica subsp. palearctica）。
