Differentially expressed genes in rough and smooth colony isolates of Clostridioides difficile

ABSTRACT: 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.

Transcriptomic profile of a Clostridioides difficile rsbW deletion mutant compared to parental R20291 strain

Project description:RNA-seq was conducted to uncover the regulatory roles of RsbW in the lifestyle of Clostridioides difficile strain R20291. RNA were extracted from planktonic cultures, which were grown in BHI-S (Sigma-Aldrich, USA) to early stationary phase (10h). The cells were re-suspended in LETS buffer and lysed using Fast-prep 24 instrument (MP Bioscience) and RNA was extracted using 1 ml Trizol (Ambion, USA). Samples were cleaned and sequenced by Novogene Company Limited, PE150 with approximately 10 million reads per sample. After QC, reads were aligned to R20291 (NC_013316.1) with Bowtie2 and readcounts were generated with Samtools and Bedtools. Differential gene expression analysis was conducted with DESeq2 with a p-value of 0.05, differential gene expression was determined with ± -2 logFC.

Microarrays of macrophages infected with smooth or rough Brucella suis

Project description:The macrophage-Brucella interaction is critical for the establishment of a chronic Brucella infection. Smooth virulent B. suis strain 1330 (S1330) prevents macrophage cell death. However, rough attenuated B. suis strain VTRS1 induces strong macrophage cell death. To further investigate the mechanism of VTRS1-induced macrophage cell death, microarrays were used to analyze temporal transcriptional responses of murine macrophage-like J774. A1 cells infected with S1330 or VTRS1.

Identification of molecular key determinants of the Mycobacterium abscessus smooth and rough morphotypes through transcriptome analyses

Project description:In this study, we were interested to get deeper insights into the molecular mechanisms that govern the formation and selection of the different colony morphologies in Mycobacterium abscessus strains, including the potential reversibility of the rough (R) phenotype into a smooth (S) phenotype. We used next generation sequencing (NGS) and micro-array / RNAseq approaches to determine the genome sequences and transcriptomic profiles of three isogenic S/R strain couples of M. abscessus. One clinical isolate strain named CF and two collection strains referred as 19977-AT and 19977-IP. To perform the transcriptomic comparison of the rough variant versus the smooth variant for each M. abscessus strain, a customized micro-array has been manufactured by Agilent (8 x 15k format). The design of oligonucleotides covering all protein coding sequences was done using OligoArray version 2.1 on the basis of the 4920 predicted coding sequences composing the entire M. abscessus genome. The experimental data for each of the 3 strains consisted of 6 hybridizations (3 biological replicates with dye-swap).

Differential stress transcriptome landscape of historic and recently emerged hypervirulent strains of Clostridium difficile strains determined using RNA-seq

Project description:Purpose: To determine how divergent strains of C. difficile respond to environmental changes, the transcriptomes of two historic and two recently isolated hypervirulent strains were analyzed following nutrient shift and osmotic shock. Methods: Following nutrient shift and osmotic shock, mRNA profile were determined using sequing of transcriptome in biological duplicates, using Illumina Hi-seq 2000. Results: After applying the quality control steps, for each sample, sequence reads were 90 nucleotides in length and the total number of reads per sample was ~ 26.6 million on average. Expression of more than 90% CDS was detected under the three experimental conditions combined. About 20% of these genes were indentified to be differentially expressed at 1.5 fold or more. Conclusions: Our results reveal that although C. difficile strains contain a large number of shared and strain specific genes, the majority of the differentially expressed genes were core genes. We also detected a number of transcriptionally active regions that were not part of the primary genome annotation. Some of these are likely to be small regulatory RNAs. Differential stress transcriptomes of two historic (strain 630 and 196) and two recently emerged hypervirulent strains (stain R20291 and 32g58) of C. difficile was determined by deep sequencing, in duplicate, using Illumina Hi-Seq 2000.
