RivR Is a Negative Regulator of Virulence Factor Expression in Group A Streptococcus

13 Nov 2012

Abstract excerpt

The bacterial pathogen group A Streptococcus (GAS) causes human diseases ranging from self-limiting pharyngitis (also known as strep throat) to severely invasive necrotizing fasciitis (also known as the flesh-eating syndrome). To control virulence factor expression, GAS utilizes both protein- and RNA-based mechanisms of regulation. Here we report that the transcription factor RivR (RofA-like protein IV)...
