Final answer:
Diagnosis of parasitic infections by observing feces commonly involves microscopic examination for the presence of parasite eggs or segments and should be carried out over several days using a stool O&P exam.
Step-by-step explanation:
Diagnosis of Parasitic Infections in Animals
An assistant can be very useful in diagnosing parasitic infections in animals by observing the animal's feces.
This diagnosis typically involves a microscopic examination of the stool to identify the presence of parasite eggs, larvae, or segments, which can provide crucial information on the type of parasitic infection.
Since parasites can shed their eggs intermittently, it is often recommended to collect and examine specimens on multiple days, ideally for at least a week.
This method is known as a stool ova and parasite (O&P) exam. For more thorough diagnostic results, concentration techniques, serology, molecular testing, and immunological assays like ELISA may be utilized.
Depending on the identified parasite, the treatment can vary; common options include mebendazole, albendazole, ivermectin, metronidazole, tinidazole, and praziquantel.
