Q1. Write the detailed account of diagnostic tools used in disease manifestation.
- Microscopic examination directly visualizes parasites (eggs, larvae, trophozoites) in host samples.
- Immunodiagnostics (ELISA, IFA) detect parasite antigens or host antibodies for infection diagnosis.
- Molecular methods like PCR offer high sensitivity and specificity by detecting parasite nucleic acids.
- Imaging techniques (Ultrasound, CT, MRI) identify deep-seated parasitic lesions and organ damage.
Answer: Parasitic disease diagnosis is crucial for effective treatment and control, often requiring a combination of methods to confirm the presence of the pathogen or its immunological signature. These diagnostic tools aim to identify the parasite, its products, or the host's immune response to infection. The choice of method depends on the parasite species, stage of infection, and available resources. **Microscopic Examination** is a cornerstone of parasitology diagnostics, involving the direct visua...
