  • Genome Signature-Based Dissection of Human Gut Metagenomes to Extract Subliminal Viral Sequences
    ARTICLE Received 16 Apr 2013 | Accepted 8 Aug 2013 | Published 16 Sep 2013 DOI: 10.1038/ncomms3420 OPEN Genome signature-based dissection of human gut metagenomes to extract subliminal viral sequences Lesley A. Ogilvie1, Lucas D. Bowler1, Jonathan Caplin2, Cinzia Dedi1, David Diston2,w, Elizabeth Cheek3, Huw Taylor2, James E. Ebdon2 & Brian V. Jones1 Bacterial viruses (bacteriophages) have a key role in shaping the development and functional outputs of host microbiomes. Although metagenomic approaches have greatly expanded our understanding of the prokaryotic virosphere, additional tools are required for the phage- oriented dissection of metagenomic data sets, and host-range affiliation of recovered sequences. Here we demonstrate the application of a genome signature-based approach to interrogate conventional whole-community metagenomes and access subliminal, phylogen- etically targeted, phage sequences present within. We describe a portion of the biological dark matter extant in the human gut virome, and bring to light a population of potentially gut- specific Bacteroidales-like phage, poorly represented in existing virus like particle-derived viral metagenomes. These predominantly temperate phage were shown to encode functions of direct relevance to human health in the form of antibiotic resistance genes, and provided evidence for the existence of putative ‘viral-enterotypes’ among this fraction of the human gut virome. 1 Centre for Biomedical and Health Science Research, School of Pharmacy and Biomolecular Sciences, University of Brighton, Brighton BN2 4GJ, UK. 2 School of Environment and Technology, University of Brighton, Brighton BN2 4GJ, UK. 3 School of Computing, Engineering and Mathematics, University of Brighton, Brighton BN2 4GJ, UK. w Present address: Mikrobiologische and Biotechnologische Risiken Bundesamt fu¨r Gesundheit BAG, 3003 Bern, Switzerland.

Lyngby DK-2800, Denmark 4 Institute of Animal Science, Hellenic Agricultural Organization DEMETER, Paralimni, Greece e-mail of the corresponding author: [email protected] Keywords: anaerobic digestion; metagenomics; metagenome-assembled genomes; taxonomy. INTRODUCTION In the past four years many samples collected from full-scale biogas plants and lab-scale reactors have been investigated using Illumina shotgun sequencing approaches and deposited in NCBI Sequence Read Archive database. In all these reactors, the Anaerobic Digestion (AD) process is performed by a plethora of different microorganisms organized in a complex functional network where different species have distinct roles in degradation of organic matter. Difficulties associated to cultivation of many prokaryotes present in natural and engineered ecosystems strongly limits the possibility to expand our knowledge regarding their physiology, genetics and function (Tringe and Rubin, 2005). Thanks to the bioinformatics approaches recently developed, which allow the reconstruction of microbial genomes starting from shotgun DNA sequences obtained from mixed cultures (Campanaro et al., 2016), it is now becoming possible to reveal the functional roles of microbial species resisting cultivation in axenic cultures.

ABSTRACT The sequencing, assembly, and basic analysis of microbial genomes, once a painstaking and expensive undertaking, has become much easier for research labs with access to standard molecular biology and computational tools. However, there are a confusing variety of options available for DNA library preparation and sequencing, and inexperience with bioinformatics can pose a significant barrier to entry for many who may be interested in microbial genomics. The objective of the present study was to design, test, troubleshoot, and publish a simple, comprehensive workflow from the collection of an environmental sample (a swab) to a published microbial genome; empowering even a lab or classroom with limited resources and bioinformatics experience to perform it. Subjects Bioinformatics, Genomics, Microbiology Keywords Workflow, Microbial genomics, Genome sequencing, Genome assembly, Bioinformatics INTRODUCTION Thanks to decreases in cost and diYculty, sequencing the genome of a microorganism is becoming a relatively common activity in many research and educational institutions.

While automated binning software and their 18 combination produce prokaryotic bins in high-throughput, their manual refinement has been 19 slow and sometimes difficult. Here, we present uBin, a GUI-based, standalone bin refiner that 20 runs on all major operating platforms and was specifically designed for educational purposes. 21 When applied to the public CAMI dataset, refinement of bins was able to improve 78.9% of 22 bins by decreasing their contamination. We also applied the bin refiner as a standalone binner 23 to public metagenomes from the International Space Station and demonstrate the recovery of 24 near-complete genomes, whose replication indices indicate active proliferation of microbes in 25 Earth’s lower orbit.

  • A Decade of Genomic History for Healthcare-Associated Enterococcus Faecium in the United Kingdom and Ireland
    Downloaded from genome.cshlp.org on September 30, 2021 - Published by Cold Spring Harbor Laboratory Press Research A decade of genomic history for healthcare-associated Enterococcus faecium in the United Kingdom and Ireland Kathy E.

We undertook whole-genome sequencing (WGS) of 495 E. faecium bloodstream isolates from 2001–2011 in the United Kingdom and Ireland (UK&I) and 11 E. faecium isolates from a reference collection. Comparison between WGS and multilocus sequence typing (MLST) identified major discrepancies for 17% of isolates, with multiple instances of the same sequence type (ST) being located in genetically distant positions in the WGS tree. This confirms that WGS is superior to MLST for evolutionary analyses and is more accurate than current typing methods used during outbreak investigations.
