Most notably the functional categories that were affected include Virulence genes, carbohydrate genes and lipid synthesis genes. Some of the virulence genes were down regulated by more than 16-32 fold. These results indicate that SDH plays an important role in the regulation of virulence.2011/06/15GSE15231GSM380334GSM380322GSM380333GSM380332GSM380310GSM380321GSM380320GSM380331829015231Streptococcus pyogenes[21628503]
