Project description:Purpose: to determine the differentially expressed genes in the phase-variable rough and smooth colony isolates of C. difficile Methods: C. difficile R20291 was grown on BHIS agar to obtain distinct colonies. Individual rough and smooth colonies were chosen for propagation on BHIS-agar for 24 hours as described in Garrett, et al., PLoS Biology, 2019. Growth was collected from n = 2 biological replicates. RNA was purified using TriSure and chloroform, beadbeating, and isopropanol/ethanol precipitation. Quality was verified with Bioanalyzer Assay. Samples were submitted to Genewiz for depletion of rRNA using the TruSeq RiboZero Gold Kit, library preparation, and single-end sequencing on the Illumina HiSeq 2500 platform. RNA sequencing analysis was done using CLC Genomic Workbench v20. Reads were mapped to C. difficile R20291 genome using the software's default menalties for mismatch, deletion, and insertion differences from the reference genome. Transcript reads were normalized as RPKM. Results: 88 genes were differentially expressed between bacteria from rough versus smooth colonies, with equal to or greater than a 2-fold change and p < 0.05 with FDR correction.

Project description:This experiment set contains the raw data for 8 arrays that were used in the genomic typing of the pre- and post-mouse H. pylori strains SS1 and SS2000. 10700 is the pre-mouse clinical isolate of SS1 and PMSS2000 is the pre-mouse clinical isolate of SS2000. gDNA from these strains were labeled and hybridized to H. pylori microarrays as described in Salama et al. {Salama et al. 2000 PNAS 97:14668-73}. In each case the test gDNA sample was labeled with Cy5 (red) and this was hybridized with Cy3 (green) labeled reference DNA of equal amount. The reference DNA consisted of equal amounts of gDNA from the two H. pylori strains used to make the H. pylori microarray, 26695 and J99. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Keywords: Logical Set
