A mutant of the antibiotic resistance factor R124 with altered copy number.

J J Pritchard, R J Rowbury.   

Abstract

A mutation conferring increased antibiotic resistance on Salmonella typhimurium strain 11G carrying R124 was plasmid determined; strains harbouring the mutant plasmid contained more DNA as ccc plasmid than those harbouring R124. The increased copy number was manifested at all growth rates tested.
