Practice questions on Barr Virus
Where is the niche for Epstein-Barr virus in humans?
- Respiratory epithelium
- Thoracic nerves
- Liver
- Lymphoid tissue and salivary glands
Answer: D. EBV establishes latency in B lymphocytes (lymphoid tissue) and reactivates in salivary gland epithelium, explaining why it is shed in saliva and transmitted via kissing. This dual tropism is central to its biology. ---
