Answer
Psittacosis is a disease that is caused by a bacteria called Chlamydia psittaci. The bacteria can be spread from birds to humans through contact with their droppings, feathers, or saliva. The disease can cause symptoms such as fever, cough, sore throat, and headache. In severe cases, psittacosis can lead to pneumonia or other complications. In the 1940s, Burnet developed a therapeutic strategy using a myxoma virus to treat psittacosis.
