Salmonella typhimurium LT2 and its mutants carry a large plasmid of molecular weight 60×106. Strains lacking autonomous plasmid DNA have been isolated. No plasmiddetermined functions have been identified, other than replication and a possible involvement in gene duplication. The plasmid neither co-transfers non-transmissible plasmids nor is itself co-transferred by F with which it does not exhibit superinfection immunity. Its replication, like that of F, is dependent on some host functions and on continuing protein synthesis.
