About Haemonchus placei
The nematode Haemonchus placei, or large stomach worm, twisted wire worm, is primarily a parasite of ruminants in tropical regions. The disease haemonchosis is characterised by anemia, edema, and weight loss and very heavy infections often cause death in young and well-fed animals.
Genome Assembly & Annotation
The draft genome assembly was produced by the Parasite Genomic group at the Wellcome Trust Sanger Institute, in collaboration with John Gilleard (University of Calgary) as part of the 50 Helminth Henomes project. The assembly uses Illumina paired-end sequencing followed by an in-house genome assembly pipeline comprising various steps, including contig assembly, scaffolding, gap-filling and error-correction.
The gene predictions were made by the Parasite Genomics group at the Wellcome Trust Sanger Institute and WormBase, as part of the 50 Helminth Genomes Initiative. An in-house pipeline was developed that used MAKER to generate high-quality annotations by integrating evidence from multiple sources: ab initio gene predictions from AUGUSTUS, GeneMark-ES, and SNAP; projected annotation from C. elegans (using GenBlastG) and the taxonomically nearest reference helminth genome (using RATT); and ESTs, mRNAs and proteins from related organisms aligned to the genome using BLAST, with refinement of alignments using Exonerate.
