(Submitter supplied) Streptococcus pyogenes or group A Streptococcus (GAS) is a leading cause of bacterial pharyngitis, skin and soft tissue infections, life-threatening invasive infections, and the post-infectious autoimmune syndromes of acute rheumatic fever and post-streptococcal glomerulonephritis. Genetic manipulation of this important pathogen is complicated by resistance of the organism to genetic transformation. more...

(Submitter supplied) In Streptococcus pyogenes, mutation of GidA results in avirulence despite the same growth rate as the wild type. To understand the basis of this effect, global transcription profiling was conducted. Keywords: Wild type vs. GidA mutant Streptococcus pyogenes

(Submitter supplied) We investigated the covS-regulation of S. pyogenes in a hypervirulent M23 strain using RNA-sequencing. The differential gene expression comparison between the covS- mutant and isogenic wild type covS+ identified altered expression of 349 (18%) genes, including a broad spectrum of virulence genes and diverse metabolic genes. The data showed that the strain achieved hypervirulence by enhancing the expression of genes responsible for invasiveness and antiphagocytosis (i.e., hasABC), by abrogating the expression of toxic genes (i.e., speB), and by compromising gene products with dispensable functions (i.e., sfb1). more...
