Which method identifies ectoparasites such as mites, lice, fleas, ticks, and flies?

• A. Visual inspection or skin scraping viewed under a microscope
• B. Blood smear
• C. Urine analysis
• D. Fecal flotation

Answer: (A)

Identifying ectoparasites on an animal relies on examining the skin and surface for pests and, when needed, sampling the skin for microscopic analysis. A thorough visual inspection during a physical exam allows you to spot visible pests like fleas, lice, ticks, and flies on the coat or skin. For mites, many species live within the skin or hair follicles, so a skin scraping is performed and the sample is examined under a microscope to reveal mites, their eggs, and debris. This combination of looking directly for pests and using a skin sample under the microscope is the most direct and effective way to detect ectoparasites. The other tests assess different issues: a blood smear looks for blood-borne parasites or abnormalities in blood cells; urine analysis evaluates kidney or urinary tract problems and sediment; and fecal flotation finds eggs or cysts of intestinal parasites, not organisms living on the skin.
