Analysis of the plasmid deoxyribonucleic acid complement of high– and low– virulent strains of the fish pathogen Vibrio anguillarum showed a correlation between enhanced virulence and the presence of a 50–megadalton plasmid class.  All 50–megadalton plasmids isolated from different high–virulent V. anguillarum strains were homologous as judged by the analysis of plasmid deoxyribonucleic acid–deoxyribonucleic acid hybridization.  The 50–megadalton plasmid class did not have polynucleotide sequences in common with plasmids of different incompatibility groups.
