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
The assembly presented here has been sequenced at the Parasite Genomics group at the Wellcome Sanger Institute. The previous reference genome (Laing et al. (2013)) was improved through additional sequencing with long PacBio reads and optical mapping, giving a chromosome-level assembly (described in Doyle et al. (2020)).
The gene models were made by the Parasite Genomics group at the Wellcome 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 ongoing manual curation. The annotation presented here is a snapshot from Spring 2020.
