Which parasite is most likely to be missed by a routine faecal flotation test because its eggs are relatively heavy?
Correct answer: B. Fasciola hepatica
- A. Toxocara canis
- B. Fasciola hepatica
- C. Ancylostoma caninum
- D. Trichuris suis
Explanation
Fasciola hepatica eggs are large and operculated, with a relatively high specific gravity, so they may fail to float in ordinary flotation solutions. Sedimentation techniques are therefore preferred for detecting them.

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.
