<i>Staphylococcus</i> Efflux <i>msr</i> (A) Gene Characterized in <i>Streptococcus</i> , <i>Enterococcus</i> , <i>Corynebacterium</i> , and <i>Pseudomonas</i> Isolates

Abstract

The staphylococcal msr(A) gene, coding for a macrolide efflux protein, was identified in three new gram-positive genera and one gram-negative genus. These msr(A) genes shared 99 to 100% identity with each other and the staphylococcal gene. This study demonstrates that the msr(A) gene has a wider host range than previously reported.
