Eventually, SARS became known as a coronavirus and became known as SARS coronavirus or SARS-CoV. So in what living organism did this disease originate? That answer is unclear, but the coronavirus was detected in bats, as well as civets. Q-fever, Psittacosis and Lyme disease are cause by bacterium. When the agent of Q-fever, Coxiella burnetii, was found, researchers started looking for the source. It actually has multiple sources, most of which are cattle, sheep and goats. Psittacosis is also known as parrot fever. It first occurred in 1892 in Paris after two animal dealers got infected and in turn infected others with the disease.
