Final answer:
Eggs of Oxyuris equi can be diagnosed by microscopic examination using a stool O&P exam or the 'Scotch tape test' to collect and identify eggs, with mebendazole, albendazole, and pyrantel pamoate being effective treatments.
Step-by-step explanation:
Eggs of Oxyuris equi, also known as equine pinworms, are typically diagnosed by a microscopic examination of fecal matter. Diagnosis may involve the use of a method known as the stool ova and parasite (O&P) exam, which is a direct examination of stool samples to identify the presence of parasites and their eggs. A common practice is to collect stool samples over multiple days to increase the chance of detection.
Additionally, other diagnostic methods such as the 'Scotch tape test' may be utilized, wherein transparent tape is used to collect eggs from around the anus in the morning, which are then examined microscopically. Following diagnosis, effective treatments include medications such as mebendazole, albendazole, and pyrantel pamoate.
