M1 MGAS5005 TrxR+ vs. TrxR- mutant


ABSTRACT: The aim of this study was to determine the extent of the trxR regulon in the M1 serotype MGAS5005. Gold, Leday, McIver 2008 Keywords: Wild-type vs trxR- series contains MGAS5005 and MGAS5005.trxR (trxR-) from three independent isolations. cDNA ratios from these isolations as well as their dye swap included

Coordinate regulation of virulence factors by the group A streptococcus (GAS) Streptococcus pyogenes is important in this pathogen's ability to cause disease. To further elucidate the regulatory network in this human pathogen, the CovR-repressed two-component system (TCS) trxSR was chosen for further analysis based on its homology to a virulence-related TCS in Streptococcus pneumoniae. In a murine skin infection model, an insertion mutation in the response regulator gene, trxR, led to a signific  ...[more]
