What's the difference between lungworm and nematode?
Lungworm
Definition:
(n.) Any one of several species of parasitic nematoid worms which infest the lungs and air passages of cattle, sheep, and other animals, often proving fatal. The lungworm of cattle (Strongylus micrurus) and that of sheep (S. filaria) are the best known.

(17) Despite the heavy challenge with lungworm larvae experienced by the grazing calves in the first year those vaccinated with lungworm vaccine survived, their clinical signs were mild and of short duration and their faecal larval output was greatly reduced.

Nematode
Definition:
(a. & n.) Same as Nematoid.
Example Sentences:

(11) Hypoproteinaemia, attributed to serum albumin loss, was demonstrated seven weeks after infection, but this was not associated with the interaction of Cu deficiency and nematode infection.
