Which anthelmintic class primarily acts by disrupting parasite microtubule formation?
Correct answer: C. Benzimidazoles
- A. Salicylanilides
- B. Macrocyclic lactones
- C. Benzimidazoles
- D. Imidazothiazoles
Explanation
Benzimidazoles bind parasite beta-tubulin and interfere with microtubule assembly, reducing nutrient uptake and energy production. Macrocyclic lactones mainly alter glutamate-gated chloride channels, so they have a different primary target.

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.
