Project description:Purpose: Examining the transcriptome of Bacteroides thetaiotaomicron VPI-5482 challenged with Bacteroides phage to assess surface molecule expression changes Methods: Bacteroides thetaiotaomicron was grown in BPRM in vitro or Germ-Free mice were monocolonized with Bacteroides thetaiotaomicron and gavaged with ARB25 phage. Fold change was calculated as live phage versus heat-killed phage treated samples with n=3 biological replicates. Once cells reached an optical density corresponding to mid-log phase growth (absorbance between 0.4-0.5), RNA was isolated and rRNA depleted. Samples were multiplexed for sequencing on the Illumina HiSeq platform at the University of Michigan Sequencing Core. Data was analyzed using Arraystar software (DNASTAR, Inc.) using DEseq2 normalization with default parameters. Genes with significant up- or down-regulation were determined by the following criteria: genes with an average fold-change >5-fold and with at least 2/3 biological replicates with a normalized expression level >1% of the overall average, and a p-value < 0.05 (t test with Benjamini-Hochberg correction) Results: Specific capsule expression was increased in wild-type B. thetaiotaomicron during phage infection in vitro and in vivo. Many corresponding in vivo genes were upregulated as well as other surface layer proteins.

Project description:Purpose: Examining the transcriptome of human gut bacteria (Bacteroides xylanisolvens/Bacteroides ovatus) that grow on mucin O-linked glycans as a sole carbon source Methods: Strains were grown on 10 mg/ml mucin O-linked glycans (MOG) or 5 mg/ml glucose as a sole carbon source in vitro. Fold change was calculated as MOG over glucose. Once cells reached an optical density corresponding to mid-log phase growth, RNA was isolated and rRNA depleted. Samples were multiplexed for sequencing on the Illumina HiSeq platform at the University of Michigan Sequencing Core. Data was analyzed using Arraystar software (DNASTAR, Inc.) Genes with significant up- or down-regulation were determined by the following criteria: genes with an average fold-change >10-fold and biological replicates with a normalized expression level >1% of the overall average RPKM expression level. Results: We identified genes activated in response to mucin O-linked glycans from Bacteroides xylanisolvens/Bacteroides ovatus strains

Project description:Investigation of whole genome gene expression level changes in a Bacteroides fragilis NCTC 9343 delta-ungD1 delta-ungD2 double mutant compared to the wild-type strain. Keywords: expression analysis A six chip study using total RNA recovered from three separate wild-type cultures of Bacteroides fragilis NCTC 9343 and three separate cultures of a double mutant strain, Bacteroides fragilis NCTC 9343 delta-ungD1 delta-ungD2, in which ungD1 (BF1706) and ungD2 (BF2848) are deleted. Each chip measures the expression level of 4,302 genes from Bacteroides fragilis NCTC 9343 and the associated plasmid pBF9343 with fourteen 24-mer probe pairs (PM/MM) per gene, with three-fold technical redundancy.
