Abstract The structural relation of YOP-1 of “european” and “american” Yersinia enterocolitica serotypes O∶3, O∶9, O∶5, 27, and O∶8 and O∶20, respectively, and Y. pseudotuberculosis serotypes I, II, and III was compared by sodium dodecyl sulfate polyacrylamide gel electrophoresis and peptide mapping using Staphylococcus aureus protease V8. Apparent molecular weights of YOP-1 ranged from 206,000 (O∶3) to approx. 180,000 (O∶8). According to their respective peptide maps YOP-1 of the “european” and “american” Y. enterocolitica serotypes and Y. pseudotuberculosis serotypes could be assigned to three different groups. Evaluation of several isolates of Y. enterocolitica serotypes O∶3, O∶9, and O∶8 by peptide mapping indicated that YOP-1 is conserved within a serotype. However, one serotype O∶8 isolate differed from the consensus peptide pattern of the other serotype O∶8 and O∶20 isolates. The similarity of the peptide patterns of Yersinia serotypes which predominate in certain geographical locations, i. e., “european” and “american” Y. enterocolitica serotypes, suggest common evolution of YOP-1 of these serotypes independent of the evolution of the other serotypes.
