About Parastrongyloides trichosuri

The nematode Parastrongyloides trichosuri is an intestinal parasite of Australian Brush-tailed possums. This parasite has the capacity to undergo multiple reproductive cycles as a free-living worm and thereby amplify the numbers of its infective L3s in faeces. This unique feature makes P. trichosuri a model for studies that explore the genetic basis of longevity and parasitism.

Genome Assembly & Annotation

Assembly

The draft genome assembly was produced by the Parasite Genomic group at the Wellcome Trust Sanger Institute, in collaboration with Warwick Grant (La Trobe University), using Illumina paired-end sequencing followed by an in-house genome assembly pipeline comprising various steps, including contig assembly, scaffolding, gap-filling and error-correction, followed by some bespoke manual improvement (WTSI Strongyloididae Nematode Genomes Project, Hunt et al. (2016)).

Annotation

The gene predictions were made by the Parasite Genomics group at the Wellcome Trust Sanger Institute as part of the Strongyloididae Nematode Genomes Project, Hunt et al. (2016). An in-house automatic pipeline (based around AUGUSTUS plus MAKER) was used to generate first-pass gene models, and this was followed by a round of targeted manual curation of selected gene families.
