Question	Answer		Article
What is Chicken Anaemia Virus Disease also commonly known as?	Chicken anaemia Chicken infectious anaemia Blue wing disease		Link to Article
Which virus causes Chicken Anaemia Virus Disease and what are it's properties?	Chicken anaemia virus (CAV): Non-enveloped icosahedral single stranded DNA (ssDNA) virus 23-25 nm diameter Small circular genome of negative sense Very hardy and resistant to high temperatures, acidic pH (pH3), chloroform and commercial disinfectants. Morphologically and antigenically different to other circoviruses such as Porcine circovirus (PCV) and Psittacine beak and feather disease virus (PBFDV).		Link to Article
What family does the Chicken anaemia virus (CAV) belong to?	Circoviridae		Link to Article
What chemicals destroy the virus?	Hypochlorite and iodophor Formalin only reduces its infectivity.		Link to Article
How many proteins does CAV produce?	Three: Non-enveloped icosahedral single stranded DNA (ssDNA) virus VP1 (52kDA) - structural protein; intracellular form of the capsid protein VP2 (24 kDA) - found in small amounts in the purified virus (Vaccines need to contain both of these to be antigenic). VP3 (14 kDA) - involved in apoptosis (programmed and controlled cell death with no lysis of the cell. Causes apoptosis of infected stem cells in the bone marrow (BM). Sequential damage to BM inhibits the production of red blood cells (RBC), white blood cells (WBC), lymphoid tissue and platelets Due to its apoptotic properties VP3 has the potential to be an anti-cancer agent		Link to Article
