(ornithosis, parrot fever)

Psittacosis is a disease caused by a microorganism called Chlamydia psittaci. It is usually transmitted to humans from birds, especially parakeets and parrots, but also from species like pigeons, turkeys, and ducks.

Since this disease is spread by birds, it occasionally occurs in pet store workers or people who have recently purchased an infected pet bird. It may also be found in farmers and slaughterhouse workers who process turkeys and ducks.
