|q1=Which equine nematode species may be found in the large intestine?
|a1=
*Strongylus species
*Cyathostomins
*Triodontophorus species
*Oxyuris equi
|l1=:Category:Horse Nematodes
|q2=Describe the gross morphology of large strongyles
|a2=
*Stout worms, 1.5-5cm long
*Large buccal capsule
*Bursa visible to the naked eye (male worms only)
|l2=Large Strongyles
|q3=What is the cause of verminous endarteritis?
|a3=The larvae of S. vulgaris within the cranial mesenteric artery
|l3=Strongylus vulgaris
|q4=Describe the pathogenicity of small strongyles
|a4=Adult and larval worms are plug feeders, restricting the damage to more superficial mucosa
|l4=Cyathostomins
|q5=What are the sources of infections of strongyles?
|a5=
*Overwintered L3 on pasture
*Many adult horses pass significant numbers of strongyle eggs throughout their lives
*Spring rise in faecal egg output occurs in both breeding and non-breeding horses
|l5=Strongyles#General epidemiology of large and small strongyles
|q6=Describe how features of ''Parascaris equorum'' eggs aid their resistance in the environment?
|a6=
*Thick, pitted shell ensures prolonged survival (>1year)
*Sticky outer shell aids passive spread
|l6=Parascaris equorum
|q7=Which is generally the first parasite to which foals are exposed?
|a7=Strongyloides westeri
|l7=Strongyloides
|q8=Describe the pathogenicity of Oxyuris equi larvae
|a8=
*Feed on colon mucosa
*Nip off epithelium
*Not true plug-feeders (erosions)
|l8=Oxyuris equi
|q9=Name the Spiruroids that can occur in the equine stomach
|a9=
*Habronema microstoma
*Draschia megastoma
|l9=Habronema and Draschia spp.
|q10=What is the pathogenicity of the equine lungworm ''Dictyocaulus arnfieldi?
|a10=
*Raised areas of over-inflated pulmonary tissue (several cms in diameter) surrounding small bronchus containing worms and mucopurulent exudate
*Hyperplastic bronchial epithelium
*Peribronchial cuffing
|l10=Dictyocaulus arnfieldi
|q11=Name some control strategies for ''Dictyocaulus arnfieldi
|a11=
*Do not keep horses on pastures grazed by donkeys (potential carriers)
*Treat donkeys with appropriate anthelmintic in spring if grazed with horses
|l11=Dictyocaulus arnfieldi
