Question

Which one of the following categories of methods CANNOT be used for animal virus detection?

• A. Serology
• B. Nucleic acid hybridization
• C. Hematology
• D. Hemagglutination

Hint:

When studying virus detection, focus on techniques that identify viral components (like nucleic acids or proteins) or immune responses. Hematology is unrelated to direct viral detection.

Answer 1

The Correct Option is C

Step 1: Understand the purpose of virus detection methods.
Detection of animal viruses typically involves techniques that identify the virus itself (via its genetic material or proteins) or the body’s immune response to it.
Step 2: Analyze each method.
Serology: Involves detecting antibodies or antigens in the blood. It is a widely used technique for virus detection, including ELISA and Western blot assays.
Nucleic acid hybridization: Involves detecting viral RNA or DNA using complementary probes. Techniques like PCR (Polymerase Chain Reaction) are based on this principle and are commonly used in virology.
Hemagglutination: Some viruses (like influenza) can cause agglutination (clumping) of red blood cells, which is used in assays to detect viral presence.
Hematology: This is the study of blood and its components (e.g., red and white cells, platelets), mainly used to diagnose blood disorders, not directly to detect viruses.
Step 3: Conclusion.
Hematology is not a direct method for detecting viruses in animals, unlike the other three.
