title: The virulence plasmid of Salmonella dublin: detailed restriction map and analysis by transposon mutagenesis.
abstract: A detailed restriction map of the virulence plasmid of Salmonella dublin has been determined and used for comparison with the virulence plasmid from S. typhimurium. Two regions were identified which appeared to be similar based on blotting and restriction data. One, of about 22 kb, encompassed the virulence region; the other, of about 8 kb, was outside it. The locations of 259 transposon insertions on the S. dublin plasmid were determined and related to their effect on virulence. One gene involved in virulence but outside the essential virulence region was shown to affect citrate metabolism.
