Which bird eggs are most commonly used for viral propagation in microbiology laboratories?

• A. Goose eggs
• B. Duck eggs
• C. Chicken eggs
• D. Quail eggs

Answer: (C)

Verified step by step guidance

1. Understand the context: Viral propagation in microbiology laboratories often requires a living system where viruses can replicate. Eggs provide a sterile, nutrient-rich environment suitable for this purpose.
2. Identify the common types of eggs used: The options given are goose eggs, duck eggs, chicken eggs, and quail eggs. Each type of egg has different sizes and availability.
3. Recall that chicken eggs are the most widely used in viral propagation because they are readily available, cost-effective, and have a suitable size and structure for inoculation of viruses.
4. Recognize that chicken eggs have specific membranes and compartments (such as the allantoic cavity and amniotic cavity) that support the growth of various viruses, making them ideal for vaccine production and research.
5. Conclude that among the options, chicken eggs are the standard choice for viral propagation in microbiology laboratories due to their practicality and biological suitability.
