| Which virus causes Chicken Anaemia Virus Disease and what are it's properties? | Chicken anaemia virus (CAV):
|
Link to Article | |
| What family does the Chicken anaemia virus (CAV) belong to? | Circoviridae
|
Link to Article | |
| What chemicals destroy the virus? |
|
Link to Article | |
| How many proteins does CAV produce? | Three:
Vaccines need to contain both VP1 and VP2 to be antigenic. Due to VP3 apoptotic properties it has the potential to be an anti-cancer agent. |
