title: Conjugative plasmid conferring resistance to olaquindox.
abstract: A conjugative plasmid, pOLA52, conferring resistance to the antibiotic growth promoter olaquindox has been isolated from Escherichia coli from swine manure. It also confers resistance to ampicillin and chloramphenicol and has a high frequency of transfer between strains of E. coli. Plasmid-borne olaquindox resistance has not been demonstrated before.
