About Haemonchus contortus

The nematode Haemonchus contortus, or red stomach worm, wire worm or Barber's pole worm, is an animal endoparasite infecting wild and domesticated ruminants (including sheep and goats) worldwide. It is a very common parasite and one the most pathogenic nematodes of ruminants. Adult worms are attached to abomasal mucosa and feed on the blood. H. contortus is a close relative of the human hookworm species which makes it an important model of parasitic nematode biology that is commonly used for experimental studies.

Genome Assembly & Annotation

Assembly

The assembly presented here has been sequenced at the Parasite Genomics group at the Wellcome Trust Sanger Institute. The previous reference genome was improved through additional sequencing with long PacBio reads and optical mapping, giving a chromosome-level assembly. Manuscript in preparation.

Annotation

The gene models were made by the Parasite Genomics group at the Wellcome Trust Sanger Institute using an automated prediction tool BRAKER1 to generate preliminary gene models, which were subsequently improved using IsoSeq, incorporating orthologs using PASA and EVidenceModeler, and submitted to WormBase in summer 2018.
