[Biological properties of plasmid-free strains of Salmonella typhimurium and S. dublin].

Abstract

The study of Salmonella virulent strains has revealed that the characteristic feature of such strains is the presence of plasmids with a molecular weight of 90.2-91.5 kb for S. typhimurium and 77.2-78.5 kb for S. dublin. From Salmonella strains harboring only a single plasmid, variants with no plasmid at all have been obtained. These variants possess lower… (More)
