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.

There is 1 alternative genome project for Haemonchus contortus available in WormBase ParaSite: PRJEB506

Genome assembly: Hco_v4_coding_submitted

The H. contortus genome was sequenced by the Gasser laboratory at the University of Melbourne, as described by Schwarz et al (2013). The version of the genome represented here is that submitted directly to WormBase in 2013, which is similar to, but not exactly the same as, NCBI assembly GCA_000442195.1

Gene annotation

The gene predictions were made Cornell University, as described by Schwarz et al (2013). The version represented here is that submitted directly to WormBase in 2013.

What can I find? Protein-coding and non-coding genes, splice variants, cDNA and protein sequences, non-coding RNAs.

Comparative genomics

What can I find? Orthologues, paralogues, and gene trees across multiple species.
