Species-specific PCR assays with primers targeted to D-alanine:D-alanine ligase (ddl) encoding genes were developed for the identification of Enterococcus durans and E. hirae. The specificity of the primers was validated in a multiplex PCR on well characterised E. durans (n = 30) and E. hirae (n = 16) strains, all of which were identified correctly. This PCR procedure offers a reliable and rapid alternative to conventional phenotypic methods for speciation of these enterococci of growing clinical importance.

Abstract

Species-specific PCR assays with primers targeted to D-alanine:D-alanine ligase (ddl) encoding genes were developed for the identification of Enterococcus durans and E. hirae. The specificity of the primers was validated in a multiplex PCR on well characterised E. durans (n = 30) and E. hirae (n = 16) strains, all of which were identified correctly. This PCR procedure offers a reliable and rapid alternative to conventional phenotypic methods for speciation of these enterococci of growing clinical importance.
