Project description:Streptococcus pneumoniae (Spn) is the predominant causative organism of acute otitis media (AOM) in children. A human cDNA microarray comprising 30,968 human genome probes was used to evaluate the transcriptional changes that occur in peripheral blood mononuclear cells (PBMC) at the onset of clinical AOM caused by Spn infection in children after comparison of microarray results with the pre-infection healthy stage of the same children.
Project description:We performed a comparative study of the two control sample options with a Streptococcus pneumoniae microarray designed with three fully sequenced strains. We hybridized two of these strains (R6 and G54) as test samples using the third strain alone (TIGR4) or a mix of the three strains as the control sample.
Project description:This SuperSeries is composed of the following subset Series: GSE31815: ccpA mutant compared to D39 wild-type in Streptococcus pneumoniae in CDM + Glucose at MID-log growth phase GSE31816: ccpA mutant compared to D39 wild-type in Streptococcus pneumoniae in CDM + GLucose at transition-phase of growth (TS) GSE31817: ccpA mutant compared to D39 wild-type in Streptococcus pneumoniae in CDM + Galactose at MID-log growth phase GSE31818: ccpA mutant compared to D39 wild-type in Streptococcus pneumoniae in CDM + galactose at transition-phase of growth (TS) Refer to individual Series
Project description:Three Microarray comparisons have been preformed in this study. 1- Transcriptome comparison of the Streptococcus pneumoniae D39 wild type grown in M17 medium + 0.5 % (w/v) NAGa (NAGaM17) to M17 medium + 0.5 % (w/v) glucose (GM17) (GSM2372597 and GSM2372598). 2- Transcriptome comparison of the Streptococcus pneumoniae D39 ΔagaR to D39 wild type grown in M17 medium + 0.5 % (w/v) glucose (GM17) (GSM2372599 and GSM2372600). 3- Transcriptome comparison of the Streptococcus pneumoniae D39 ΔccpA to D39 wild type grown in M17 medium + 0.5 % (w/v) NAGa (NAGaM17) (GSM2290636 and GSM2290637).
Project description:Comparative analyses of protein expression between log-phase planktonic and 1-day and 7-day biofilm cultures from Streptococcus pneumoniae representing nascent and late phase biofilm growth were performed using the proteomic approach iTRAQ
Project description:Transcriptome comparison of the Streptococcus pneumoniae D39 wild-type grown in CDM Plus 0mM Zn2+ to grown in CDM plus 0.2 mM Zn2+.
Project description:The Antibiotic Resistant Sepsis Pathogens Framework Initiative aims to develop a framework dataset of 5 sepsis pathogens (5 strains each) using an integrated application of genomic, transcriptomic, metabolomic and proteomic technologies. The pathogens included in this initiative are: Escherichia coli, Klebsiella pneumoniae complex, Staphylococcus aureus, Streptococcus pyogenes, and Streptococcus pneumoniae. This submission pertains to strain 947.
