In veterinary parasitology, what is the defining feature of a definitive host?
Correct answer: C. It harbours the parasite's adult or sexual stage
- A. It supports multiplication of only larval stages
- B. It carries the parasite only during embryonation
- C. It harbours the parasite's adult or sexual stage
- D. It transmits the parasite without harbouring it
Explanation
A definitive host contains the adult stage or the stage in which sexual reproduction occurs. An intermediate host usually carries immature or asexual stages, while a vector may transmit the parasite without being its definitive host.

About Veterinary Parasitology
Covers protozoa, helminths and arthropods that infect domestic animals, including their morphology, life cycles, hosts, transmission and clinical effects. Questions connect parasite identification with diagnosis, prevention and treatment, and distinguish endoparasites from ectoparasites and definitive hosts from intermediate hosts.
