Ubiquitous occurrence of virR and scpA genes in group A streptococci

Abstract

Until now a few serotypes of M-class I group A streptococci (GAS) have been shown to encode VirR, a positive regulatory factor for the coordinate expression of the M protein (emm) and C5a peptidase (scpA) genes. The polymerase chain reaction technique has been applied to the genomic template of 36 GAS serotypes to demonstrate the general presence of VirR… (More)
