    Description

    In order to test for the differential abundance of taxa that may drive the differences observed between inferred microbial communities derived from the different DNA isolation procedures, we performed DESeq2 analyses. Here we provide an example for such an analysis from human fecal specimen, examined using 16S rRNA gene profiling. This workflow relates to the article: Berith E. Knudsen, Lasse Bergmark, Patrick Munk, Oksana Lukjancenko, Anders Priemé, Frank M. Aarestrup, Sünje J. Pamp (2016) Impact of Sample Type and DNA Isolation Procedure on Genomic Inference of Microbiome Composition. mSystems Oct 2016, 1 (5) e00095-16; DOI: 10.1128/mSystems.00095-16

    Description

    Amplicon sequencing utilizing next-generation platforms has significantly transformed how research is conducted, specifically microbial ecology. However, primer and sequencing platform biases can confound or change the way scientists interpret these data. The Pacific Biosciences RSII instrument may also preferentially load smaller fragments, which may also be a function of PCR product exhaustion during sequencing. To further examine theses biases, data is provided from 16S rRNA rumen community analyses. Specifically, data from the relative phylum-level abundances for the ruminal bacterial community are provided to determine between-sample variability. Direct sequencing of metagenomic DNA was conducted to circumvent primer-associated biases in 16S rRNA reads and rarefaction curves were generated to demonstrate adequate coverage of each amplicon. PCR products were also subjected to reduced amplification and pooling to reduce the likelihood of PCR product exhaustion during sequencing on the Pacific Biosciences platform. The taxonomic profiles for the relative phylum-level and genus-level abundance of rumen microbiota as a function of PCR pooling for sequencing on the Pacific Biosciences RSII platform were provided. Data is within this article and raw ruminal MiSeq sequence data is available from the NCBI Sequence Read Archive (SRA Accession SRP047292). Additional descriptive information is associated with NCBI BioProject PRJNA261425. http://www.ncbi.nlm.nih.gov/bioproject/PRJNA261425/ Resources in this dataset:Resource Title: NCBI Sequence Read Archive (SRA Accession SRP047292).

    Description

    Archival DNA samples collected and analysed for a range of research and applied questions have accumulated in the laboratories of universities, government agencies, and commercial service providers for decades. These DNA archives represent a valuable, yet largely untapped repository of genomic information. With lowering costs of, and increasing access to, high-throughput sequencing, we predict an increase in retrospective research to explore the wealth of information that resides in these archival samples. However, for this to occur, we need confidence in the integrity of the DNA samples, often stored under sub-optimal conditions and their fitness of purpose for downstream genomic analysis. Here, we borrow from a well-established concept in ancient DNA to evaluate sample integrity, defined as loss of information content in recovered amplicons, of frozen DNA samples and based on the ratio of ⠺-diversity of short and long-read 16S rRNA gene sequences. The 16S rRNA variable region of eight..., Data analysis The Pacific Biosciences Nextflow pipeline (https://github.com/PacificBiosciences/pb-16S-nf) was followed for initial data processing. Raw reads were processed, including demultiplexing by “q2-demux†in QIIME2, and quality control was assessed with q2-cutadapt. Quantitative Insights Into Microbial Ecology 2 (QIIME2 v. 2018.11) software was used to analyse the trimmed reorientated sequences (Bolyen et al., 2019). The DADA2 denoising option (Callahan et al., 2016) was selected to pick up the representative reads for generating an amplicon sequence variants (ASVs) table. ASVs generated from DADA2 were classified using the Naive Bayes classifier and SILVA reference database version 138.1 (Quast et al., 2013). For analysis between the platforms the feature table of each platform was merged, as were the representative sequences post-DADA2 denoising with QIIME2 before building the phylogenetic tree and assigning taxonomy.

    We utilized DNA extracted from various agricultural soils that were stored at -20°C in a gene bank freezer room over 20 years by the South Australian Research and Development Institute (SARDI). This DNA was collected through the PREDICTA® B DNA-based soil disease testing service for broadacre farming (PREDICTA® B). We selected 87 soil DNA extracts from three Australian states (regions), spanning 10 distinct time bins between 2001 and 2020. Our primary concern was the potential DNA degradation in the oldest samples. Therefore, we included samples from the first four years (2001-2004) and selected samples more sporadically from subsequent years (2005 onwards). Alpha-diversity ratios, using Shannon's diversity index, were calculated to determine if there was a d...

    Description

    Culture independent techniques, such as shotgun metagenomics and 16S rRNA amplicon sequencing have dramatically changed the way we can examine microbial communities. Recently, changes in microbial community structure and dynamics have been associated with a growing list of human diseases. The identification and comparison of bacteria driving those changes requires the development of sound statistical tools, especially if microbial biomarkers are to be used in a clinical setting. We present mixMC, a novel multivariate data analysis framework for metagenomic biomarker discovery. mixMC accounts for the compositional nature of 16S data and enables detection of subtle differences when high inter-subject variability is present due to microbial sampling performed repeatedly on the same subjects, but in multiple habitats. Through data dimension reduction the multivariate methods provide insightful graphical visualisations to characterise each type of environment in a detailed manner. We applied mixMC to 16S microbiome studies focusing on multiple body sites in healthy individuals, compared our results with existing statistical tools and illustrated added value of using multivariate methodologies to fully characterise and compare microbial communities.

    Description

    This repository contains raw data for the manuscript "Optimization of the 16S rRNA sequencing analysis pipeline for studying in vitro communities of gut commensals". While microbial communities inhabit a wide variety of complex natural environments, in vitro culturing enables highly controlled conditions and high-throughput interrogation for generating mechanistic insights. In vitro assemblies of gut commensals have recently been introduced as models for the intestinal microbiota, which plays fundamental roles in host health. However, a protocol for 16S rRNA sequencing and analysis of in vitro samples that optimizes financial cost, time/effort, and accuracy/reproducibility has yet to be established. Here, we systematically identify protocol elements that have significant impact, introduce bias, and/or can be simplified. Our results indicate that community diversity and composition are generally unaffected by substantial protocol streamlining. Additionally, we demonstrate that a strictly aerobic halophile is an effective spike-in for estimating absolute abundances in communities of anaerobic gut commensals. This time- and money-saving protocol should accelerate discovery by increasing 16S rRNA data reliability and comparability and through the incorporation of absolute abundance estimates.

    Description

    This event has been computationally inferred from an event that has been demonstrated in another species.

    The inference is based on the homology mapping from PANTHER. Briefly, reactions for which all involved PhysicalEntities (in input, output and catalyst) have a mapped orthologue/paralogue (for complexes at least 75% of components must have a mapping) are inferred to the other species. High level events are also inferred for these events to allow for easier navigation.

    Description

    This repository contains the RAW sequencing data for the herbivorous reef fish microbiome study. Trimmed reads (with primers removed) were deposited at the European Nucleotide Archive, study accession number PRJEB28397 (ERP110594).Raw fastq data files are named using the root format RunQ_GnSpe000_G, where Q is the run number (1, 2, or 3), GnSpe is the host genus and species, 00 is a unique host ID number, and G is the gut segment (F = foregut; M = midgut; H = hind). So the file name Run1_SpVir11_M_S147_L001_R2_001.fastq corresponds to: the R2 reads; midgut sample; Sparisoma viride; individual 11; Run01. Raw fastq files are deposited here by Run. To process please use the scripts in the Pipeline for 16S rRNA processing using DADA2 directory.DNA Extraction & Sequencing MethodsFor all samples, we homogenized material from each gut segment (fore, mid, hind) separately in 50mL conical tubes for 2 minutes on a Vortex Genie 2. We collected 200 mg (wet weight) of homogenate for DNA extraction following the Human Microbiome Project Core Microbiome Sampling Protocol A (v12.0, HMP Protocol # 07-001) for stool samples. Prior to extraction, we heat treated each sample, first at 65℃ f or 10 minutes, followed by 95℃ for 10 minutes. We then used the PowerSoil® DNA Isolation Kit (MoBio) following the manufacturer's protocol to extract community DNA from each sample. Extracted DNA was sequenced on an Illumina MiSeq by Integrated Microbiome Resource at the Centre for Comparative Genomics and Evolutionary Bioinformatics (Dalhousie University). We targeted the V4-V5 hypervariable region using 515F (5′-GTGYCAGCMGCCGCGGTA) and 926R (5′-CCGYCAATTYMTTTRAGT). We collected 53 individual fish encompassing seven species and three genera. Two species—Sparisoma chrysopterum and Scarus vetula—were only represented by 1 and 2 individuals, respectively. Though we chose to omit these samples from the final analysis, these samples were sequenced and analyzed along with the rest of the samples and made the data available for analysis.We generate sequence data for all 159 sample—three gut segments (fore, mid, and hind) from 53 individuals. Sequencing was conducted across three runs. In the first run (Run01), 144 samples were sequenced and, due to lower than average yield, were re-sequenced (Run02). The remaining 15 samples (5 individuals) were sequenced on a separate run (Run03).

    Description

    This dataset contains configuration and results files for the proof-of-principle of the dadasnake pipeline. Includes dadasnake output and tables with the composition of ground-truth data or mock-communities.

    dadasnake is a user-friendly, one-command Snakemake pipeline that wraps the pre-processing of sequencing reads and the delineation of exact sequence variants by using the favorably benchmarked and widely-used DADA2 algorithm with a taxonomic classification and the post-processing of the resultant tables, including hand-off in standard formats. The suitability of the provided default configurations is demonstrated using mock-community data from bacteria and archaea, as well as fungi. By use of Snakemake, dadasnake makes efficient use of high-performance computing infrastructures. Easy user configuration guarantees flexibility of all steps, including the processing of data from multiple sequencing platforms. dadasnake facilitates easy installation via conda environments. dadasnake is available at https://github.com/a-h-b/dadasnake .

Description

In order to test for the differential abundance of taxa that may drive the differences observed between inferred microbial communities derived from the different DNA isolation procedures, we performed DESeq2 analyses. Here we provide an example for such an analysis from human fecal specimen, examined using 16S rRNA gene profiling. This workflow relates to the article: Berith E. Knudsen, Lasse Bergmark, Patrick Munk, Oksana Lukjancenko, Anders Priemé, Frank M. Aarestrup, Sünje J. Pamp (2016) Impact of Sample Type and DNA Isolation Procedure on Genomic Inference of Microbiome Composition. mSystems Oct 2016, 1 (5) e00095-16; DOI: 10.1128/mSystems.00095-16
