Non-M1 covRS-intact and -mutant GAS vs M1 controls

ABSTRACT: Microarray was performed on RNA extracted from mid-logarithmic phase in vitro grown non-M1 Streptococcus pyogenes isolates, with either intact or mutant covRS operons. These isolates were compared with corresponding M1 covRS intact and mutant forms to link the expression prolfiles of these non-M1 isolates with invasive pathogenesis.

non-M1 covRS-intact and -mutant GAS vs M1 controls

Project description:Microarray was performed on RNA extracted from mid-logarithmic phase in vitro grown non-M1 Streptococcus pyogenes isolates, with either intact or mutant covRS operons. These isolates were compared with corresponding M1 covRS intact and mutant forms to link the expression prolfiles of these non-M1 isolates with invasive pathogenesis. A dye-swapped cyclic design was used in this study in order that each strain could be compared across all samples in silico. For each strain treated, 2 biological replicates were each analysed in dye-swapped technical replicates, giving a total of n=4 peplicates for each strain.

Transcriptomic comparison of serotype M1 S. pyogenes

Project description:S. pyogenes strains were compared with the intact covRS form of the globally disseminated M1T1 clone to track transcriptomic changes engendered during the emergence of the M1T1 clone. The mutant covRS form of the M1T1 clone was included as a transcriptomic outlier and to provide a context for the magnitude of transcriptional shifts detected within the isolate set examined. Microarray was performed on RNA extracted from mid-logarithmic phase S. pyogenes grown in Todd-Hewitt with 1% yeast extract in vitro. Experiments were performed using a single color method. Each sample was labelled with Cy3 and hybridized to separate arrays. Each strain was analysed in 3 biological replicates. cDNA hybridized to JCVI PFGRC Streptococcus pyogenes v2 oligo arrays. Only probed representing the core M1 genome were used for analysis.

Whole genome transcritptional comparison of Group A Streptococcus (Streptococcus pyogenes) serotype M1 pre-epidemic and epidemic isolates

Project description:This transcriptional analysis is a follow up to a population genomic investigation of 3615 Streptococcus pyogenes serotype M1 strains whch are responsible for an epidemic of human invasive infections (www.pnas.org/cgi/doi/10.1073/pnas.1403138111), The goal was to assess gene expression differences between predecessor pre-epidemic M1 strains and their descendent epidemic M1 strains to gain insights into the underlying genetic basis for the shift in the frequency and severity of human infections caused by these pathogenic bacteria The transcriptomes of 7 GAS M1 strains, 4 pre-epidemic and 3 epidemic, were compared at two phases of growth, mid-exponential and early-stationary, using 3 biologial replicates, to identify genes differentially expressed between the pre-epidemic and epidemic isolates with the goal of to gaining insight into the underlying genetic basis for the evolutionary emergence, increased frequency and severity of the epidemic strains relative to the pre-epidemic strains
