Many worm species occur in the gastrointestinal tract of sheep, though relatively few are of importance in the UK. Primary pathogens include:
{| style="width:75%; height:200px" border="1"
!
!'''Abomasum'''
!'''Small Intestine'''
!'''Large Intestine'''
|-
|'''Primary Pathogens in the UK'''
|
*''Ostertagia (Teladorsagia) circumcincta''
*''Haemonchus contortus''
|
*''Trichostrongylus'' species
*''Nematodirus battus''

*''Cooperia'' species
*''Bunostomum'' species
*''Strongyloides'' species

*''Oesophagostomum'' species
*''Chabertia'' species
*''Trichuris'' species
|}
*All the above worms belong to the '''Trichotrongyloidea''' except:
**''Bunostomum'' (a hookworm)
**''Oesophagostomum''
**''Chabertia'' (Strongyloidea)
**''Strongyloides'' (Rhabditoidea)
**''Trichuris'' (a whipworm)
*Although many different genera and species of worms may be found in the gastro-intestinal tract of sheep there are only three distinct disease manifestations within the [[Parasitic Gastroenteritis|PGE]] complex:
**Ostertagiosis and Trichostrongylosis
**Nematodirosis
**Haemonchosis[[Category:Nematodes]][[Category:Sheep Nematodes]]
