Cross-reactions between antigens from Yersinia enterocolitica serogroup 0:3 and 5 other members of the same species as well as 34 other bacterial species were studied by means of quantitative immunoelectrophoretic methods. A sonicated Y. enterocolitica antigen preparation and corresponding purified rabbit antibodies were used in a reference system that presented 58 regularly visible immunoprecipitates. One antigen was identified as specific for the Y. enterocolitica 0:3 serogroup and two antigens for the species Y. enterocolitica. Y. enterocolitica antigens cross-reacted widely with antigens from other Enterobacteriaceae, but only a few cross-reactions were registered with Gram-negative bacteria outside the Enterobacteriaceae. A partial cross-reaction between all Gram-positive bacteria included in our study and two Y. enterocolitica antigens was demonstrated.
采用定量免疫电泳方法研究了小肠结肠炎耶尔森菌0:3血清群抗原与同一菌种的其他5个成员以及34种其他细菌菌种之间的交叉反应。在一个呈现58个规则可见免疫沉淀物的参考系统中，使用了超声处理的小肠结肠炎耶尔森菌抗原制剂和相应的纯化兔抗体。一种抗原被鉴定为小肠结肠炎耶尔森菌0:3血清群所特有，两种抗原为小肠结肠炎耶尔森菌种所特有。小肠结肠炎耶尔森菌抗原与其他肠杆菌科细菌的抗原广泛交叉反应，但与肠杆菌科以外的革兰氏阴性菌仅有少数交叉反应被记录。在我们研究中纳入的所有革兰氏阳性菌与两种小肠结肠炎耶尔森菌抗原之间显示出部分交叉反应。
