Step-by-step explanation:
Symptoms of Oxyuris equi Infection
The correct answer to the question regarding the symptom of Oxyuris equi is C) Pruritus (itching around the anus). Oxyuris equi, also known as the equine pinworm, primarily causes itching around the anus in horses. This sensation prompts the infected animals to scratch the area, often against surfaces like fences, which can lead to the spread of the eggs when they adhere to the surfaces and subsequently contaminate the environment.
Additional symptoms across different parasitic infections may include diarrhea, abdominal pain, and in severe cases, other symptoms such as vomiting, nausea, and intestinal obstruction. However, with Oxyuris equi, pruritus is the primary symptom rather than these others.
Thus the correct answer to the question regarding the symptom of Oxyuris equi is C) Pruritus
