| Abstract: | A total of 75 Vibrio anguillarum serogroup O1 strains were studied with respect to their plasmid contents, ribotypes, and pulsed-field gel electrophoresis (PFGE) patterns. Eight plasmid profiles and six ribotypes were demonstrated, and one profile was dominant by both typing methods. In contrast, PFGE had very high discriminatory power, demonstrating 35 profiles. On the basis of PFGE patterns, a similarity matrix and a dendrogram were constructed. The results indicated that Scandinavian strains and southern European isolates (with some exceptions) belong to two different clonal lineages. A few strains from the United States and United Kingdom deviated considerably from each other and from Scandinavian and southern European strains. |
