Which organism can be detected by an anal tape test?

The anal tape test is specifically designed to detect the presence of enteric parasites, particularly pinworms, which are a type of nematode. In laboratory animal medicine, the test is commonly used for species like mice and rats. The test involves applying adhesive tape to the perianal area, which can pick up eggs if pinworms are present. When the tape is examined under a microscope, the eggs can be identified.

While Syphacia is indeed a genus of pinworms, this test is traditionally associated with detecting the eggs of two primary species in rodents, Syphacia obvelata and Aspicularis tetraptera. Therefore, the correct answer relates to the capability of the anal tape test to specifically identify eggs from pinworms such as those in the Syphacia genus, which highlights the usefulness of this diagnostic tool in laboratory settings.

Other options, like Giardia, are detected using different methods, such as fecal flotation or antigen tests, while Ascaris refers to a larger roundworm not usually assessed with this particular test. These distinctions are important for understanding the methods used in parasitology and the significance of the anal tape test in specific scenarios.
