454 screening of individual MHC variation in an endemic island passerine [PDF]

open access: yes, 2014
Genes of the major histocompatibility complex (MHC) code for receptors that are central to the adaptive immune response of vertebrates. These genes are therefore important genetic markers with which to study adaptive genetic variation in the wild.

Evidence of global-scale aeolian dispersal and endemism in isolated geothermal microbial communities of Antarctica [PDF]

open access: yes, 2014
New evidence in aerobiology challenges the assumption that geographical isolation is an effective barrier to microbial transport. However, given the uncertainty with which aerobiological organisms are recruited into existing communities, the ultimate ...

Amplicon sequencing of colorectal cancer: variant calling in frozen and formalin-fixed samples. [PDF]

open access: yesPLoS ONE, 2015
Next generation sequencing (NGS) is an emerging technology becoming relevant for genotyping of clinical samples. Here, we assessed the stability of amplicon sequencing from formalin-fixed paraffin-embedded (FFPE) and paired frozen samples from colorectal

Rapid genotyping of porcine reproductive and respiratory syndrome virus (PRRSV) using MinION nanopore sequencing.

open access: yesPLoS ONE, 2023
The global distribution and constant evolution are challenges for the control of porcine reproductive and respiratory syndrome virus (PRRSV), one of the most important viruses affecting swine worldwide. Effective control of PRRSV benefits from genotyping,

Diverse diazotrophs are present on sinking particles in the North Pacific Subtropical Gyre. [PDF]

open access: yes, 2019
Sinking particles transport carbon and nutrients from the surface ocean into the deep sea and are considered hot spots for bacterial diversity and activity.

Impact of DNA Sequencing and Analysis Methods on 16S rRNA Gene Bacterial Community Analysis of Dairy Products

open access: yesmSphere, 2018
DNA sequencing and analysis methods were compared for 16S rRNA V4 PCR amplicon and genomic DNA (gDNA) mock communities encompassing nine bacterial species commonly found in milk and dairy products.

Application of high-throughput sequencing to whole rabies viral genome characterisation and its use for phylogenetic re-evaluation of a raccoon strain incursion into the province of Ontario [PDF]

open access: yes, 2017
Raccoon rabies remains a serious public health problem throughout much of the eastern seaboard of North America due to the urban nature of the reservoir host and the many challenges inherent in multi-jurisdictional efforts to administer co-ordinated and ...

TOAST: a novel tool for designing targeted gene amplicons and an optimised set of primers for high-throughput sequencing in tuberculosis genomic studies

open access: yesBMC Genomics
Background Amplicon sequencing of Mycobacterium tuberculosis resistance-associated genes offers a cost-effective alternative to whole-genome sequencing for rapid profiling of infections and guiding clinical management.

Decoding fungal communities: ITS extraction matters more than ASVs vs. OTUs [PDF]

open access: yesWeb Ecology
To capture the complexity of fungal communities, microbial ecologists must often resort to amplicon sequencing. Amplicon sequences are obtained from the nuclear ribosomal internal transcribed spacer (ITS), which is currently used as a marker for fungal ...

BATCH-GE : batch analysis of next-generation sequencing data for genome editing assessment [PDF]

open access: yes, 2016
Targeted mutagenesis by the CRISPR/Cas9 system is currently revolutionizing genetics. The ease of this technique has enabled genome engineering in-vitro and in a range of model organisms and has pushed experimental dimensions to unprecedented proportions.
