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.
