Characterization of a Plasmid Determining Resistance to Erythromycin, Lincomycin, and Vernamycin B _α in a Strain of <i>Streptococcus pyogenes</i>

Abstract

A plasmid determining resistance to erythromycin, lincomycin, and vernamycin B(alpha) was isolated from a strain of Streptococcus pyogenes. The plasmid has a molecular weight of approximately 17 x 10(6) and is present to the extent of one to two copies per chromosomal genome equivalent.
