Many nematode species occur in the equine gastrointestinal tract, although not all are of equal importance:


Stomach Small Intestine Large Intestine
  • Habronema (Draschia)
  • Trichostrongylus axei
  • Parascaris
  • Strongyloides
  • Strongylus species
  • Cyathostomins
  • Triodontophorus species
  • Oxyuris equi


Strongyles (Red worms)

The strongyles that occur in the horse can be divided on the basis of size into two groups

  • Large strongyles
    • Strongylus species (3 species; used to be widespread prior to the introduction of worm control programmes; now uncommon)
    • Triodontophorus species (common)
  • Small strongyles
    • Also known as Cyathostomins (preferred term), cyathostomes, trichonemes or small redworms
    • Cyathostomins (widespread, including 4 genera and over 40 species of worms)
