Fasciola Diagnostic by:
- A- Ova in stool.
- B- Larva in stool
- C- Cyst in stool
- D- Trophozoite.
The most common method for diagnosing Fasciola infection is: A. Ova in stool.
Here's why the other options are not the primary diagnostic method:
- Larvae in stool:
Fasciola larvae do not live in the human intestines and therefore wouldn't be found in stool. They migrate through the body tissues before reaching the bile ducts, where they mature into adults.
- Cyst in stool:
Fasciola doesn't form cysts in the human body. Their life cycle involves eggs, miracidia, sporocysts, cercariae, metacercariae, and adult flukes, none of which form cysts in humans.
- Trophozoite:
Fasciola doesn't exist in the trophozoite stage. This stage is specific to certain protozoan parasites, not flukes like Fasciola.
While other tests like blood tests or imaging can be used to support the diagnosis of Fasciola infection, finding Fasciola eggs in stool remains the most direct and commonly employed method.
It's important to note that finding Fasciola eggs in stool can be challenging, especially with light infections. Multiple stool samples may be needed, and other diagnostic methods may be considered depending on the specific situation.
