title: RAPD analysis of Yersinia enterocolitica.
abstract: A total of 87 isolates of Yersinia enterocolitica were examined with randomly amplified polymorphic DNA (RAPD) by use of three different primers. Based on the RAPD profiles, the strains could be divided into three major groups: (1) the pathogenic American serotypes, O:8, O:13ab, O:20 and O:21; (2) the pathogenic European serotypes, O:3, O:5,27 and O:9; and (3) the nonpathogenic serotypes. Five tested strains of the American serotype O:4 gave unique profiles with YCPEL, but did not give reproducible profiles with the other primers. The European serotypes could be further subdivided into a group consisting of strains of O:3 and O:5,27 and a group of strains of O:9. RAPD profiling provides an easy approachable method to divide isolates of Y. enterocolitica into pathogenic and nonpathogenic strains and further to differentiate between the pathogenic isolates.
