B. fecal sedimentation.
C. a skin scraping.
D. fecal flotation.

Answer 1

Psoroptes ovis, also known as the sheep scab mite, is generally diagnosed using a skin scraping, enabling the microscopic observation of mites or eggs.

Step-by-step explanation:

Psoroptes ovis is generally diagnosed using a skin scraping. Skin scrapings are utilized to detect a variety of ectoparasites, fungi, and bacterial infections by allowing for microscopic examination of the sample. In the case of Psoroptes ovis, also known as sheep scab mite, the diagnosis is facilitated by observing the mites, eggs, or fecal pellets under a microscope. Other diagnostic methods, including direct smears and fecal examinations such as fecal flotation and fecal sedimentation, are used for different types of infections and are less commonly used when diagnosing Psoroptes ovis.
