An intestinal fluke is of the:

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

Answer: (A)

An intestinal fluke lives in the intestinal tract, and the species that fits this habitat is Alaria. These trematodes infect dogs and other carnivores and inhabit the small intestine as adults, with a life cycle that typically involves two intermediate hosts (often a snail and an amphibian) before reaching the final host. The other options are associated with different organs: Fascioloides magna is a liver fluke that resides in the liver; Stephanurus dentatus is a kidney worm of pigs; Metastrongylus species are lungworms in pigs.
