| Source name |
Bps_chronic_Control
|
| Organism |
Mus musculus |
| Characteristics |
mouse model: Burkholderia pseudomallei - chronic
condition: Control
infection protocol: Burkholderia pseudomallei strain 576 originally isolated from a melioidosis patient was provided by Dr. T. Pitt (Health Protection Agency, London, UK). Female C57BL/6 mice were infected intranasally with 50 ml containing 100 colony forming units (chronic model) of B. pseudomallei derived from cryopreserved stocks diluted in pyrogen-free saline. Control uninfected mice received 50 ml pyrogen-free saline only. Whole blood samples were collected from individual infected and control treated mice on days on days 27, 39, 49, 65 and 90 post infection.
tissue: Whole blood

total RNA |
| Extraction protocol |
Blood was collected in Tempus reagent (Life Technologies) at 1:2 ratio. Total RNA was extracted using the PerfectPure RNA Blood Kit (5 PRIME). Globin RNA was depleted from total RNA (1.5–2 µg) using the Mouse GLOBINclear kit (Ambion).
Globin-reduced RNA (200 ng) was used to prepare cDNA libraries using the TruSeq Stranded mRNA HT Library Preparation Kit (Illumina). Quality and integrity of the tagged libraries were initially assessed with the HT DNA HiSens Reagent kit (Perkin Elmer) using a LabChip GX bioanalyser (Caliper Life Sciences/Perkin Elmer). Tagged libraries were then sized and quantitated in duplicate (Agilent TapeStation system) using D1000 ScreenTape and reagents (Agilent). Libraries were normalised, pooled and then clustered using the HiSeq® 3000/4000 PE Cluster Kit (Illumina). The libraries were imaged and sequenced on an Illumina HiSeq 4000 sequencer using the HiSeq® 3000/4000 SBS kit (Illumina) at a minimum of 25 million paired-end reads (75 bp/100 bp) per sample.

| Description |
MS0039_S44_L008
|
| Data processing |
Raw paired-end RNA-seq data was subjected to quality control using FastQC (Babraham Bioinformatics) and MultiQC. Trimmomatic v0.36 was used to remove the adapters and filter raw reads below 36 bases long, and leading and trailing bases below quality 25. The filtered reads were aligned to the Mus musculus genome Ensembl GRCm38 (release 86) using HISAT2 v2.0.4 with default settings and RF rna-strandedness, including unpaired reads, resulting from Trimmomatic, using option -U. The mapped and aligned reads were quantified to obtain the gene-level counts using HtSeq v0.6.1 with default settings and reverse strandedness. Raw counts were processed using the bioconductor package DESeq2 v1.12.4 in R v3.3.1, and normalised using the DESeq method to remove the library-specific artefacts. Variance stabilizing transformation was applied to obtain normalised log2 gene expression values. Further quality control was performed using principal component analysis, boxplots, histograms and density plots.
