The parasite also known as a lungworm is of the:

• A. Alaria species
• B. Fascioloides species
• C. Stephanurus species
• D. Metastrongylus species

Answer: (D)

Lungworms live in the respiratory tract, specifically the bronchi and airways. Metastrongylus species are the lungworms most commonly associated with pigs, and they have an indirect life cycle that uses earthworms as the intermediate host. Pigs ingest an earthworm containing the infectious larvae, which migrate to the lungs and mature there, often causing coughing and bronchopneumonia. The other parasites listed occupy different sites: Alaria species are intestinal flukes, Stephanurus dentatus is a kidney worm of pigs, and Fascioloides magna is a deer liver fluke.
