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 immunoelec‐trophoretic 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.
