Integrated Analysis of Population Genomics, Transcriptomics and Virulence Provides Novel Insights into Streptococcus pyogenes Pathogenesis [50 strains]


ABSTRACT: Purpose: We used GAS as a model bacterial pathogen to investigate the complex relationship between genome, transcriptome, and virulence in a large population of type emm28 strains recovered from humans over 26 years in geographically diverse locations. Methods: We chose a subset of isolates from the sequenced population of 2,101 emm28 strains that would approximately span the genetic variation present in the entire population. Fifty emm28 strains were grown in triplicate, harvested at two time points, mid-exponential (ME) and early-stationary (ES) phases of growth, and assayed in triplicate by RNA-seq. rRNA was depleted using the Ribo-Zero rRNA removal kit for Gram-positive bacteria (Illumina) and libraries were made using the ScriptSeq complete kit for bacteria (Illumina). The cDNA libraries were prepared with indexed reverse primers from the ScriptSeq Index PCR primers kit (Illumina), and purified with AMPureXP beads (Beckman Coulter).
