The best time to perform a tape test to diagnose a pinworm infection is in the morning before bathing or using the toilet. Why?
because pinworms lay eggs at night. Bathing or using the toilet can remove the eggs from your skin.
Why does a female pinworm lay eggs in perinal area?

It helps the suspected eggs of the parasites to be more visible into the slide

Differentiate the karyosome location between Entamoeba histolytica and E. coli.
The karyosome in E. histolytica is small and centrally located. It is surrounded by a halo of chromatin granules while entamoeba coli is the karyosome in E. coli is larger than the karyosome in E. histolytica and is eccentrically located. It is not surrounded by a halo of chromatin granules
The diagnostic method for Giardia lamblia
Fecal microscopy analysis
What specimen is used in the diagnosis of Trichomoniasis?

How is Balantidiasis prevented?
1.Clean water
2. Proper disposal of waste
3. Avoid contact with infected pigs
4. Avoid using night soil
Why does the diagnosis of Trichonosis does not use fecal samples?
Because larvae travel to the bloodstream to bury inside the muscle tissue
How does the Capillaria population increase?
Via autoinfection
What is the role of humans and fish to the Capillaria population?
Human as definitive host and fish as intermediate host
What is the role of humans to the life cycle of Trichinella spiralis ?
Human as a host aids for the development and growth of these parasites to reach its complete life cycle
Why is enterobiasis considered familial disease?
When one member of the family is infected, there are higher chances that the entire family is also infected.
