'''Post mortem examination''' findings include: rabbit is usually in good condition. There is hepatic necrosis and splenomegaly. The liver is usually pale, and has a fine reticular pattern of necrosis outlining eac lobule. The spleen in usually black and thickened with rounded edges. The kidneys may be very dark brown. Haemorrhages in the lungs, trachea and thymus are common, and petechiae may be found on the serosal membranes or viscera. Infarctions may be seen in most organs.

It is generally recommended that all animals should be vaccinated, even if the rabbit is kept indoors, as spread from fomites is possible. More information on the vaccine available in the UK can be found [[Vaccinations for Rabbits|here]].
