Parrot Fever, Psittacosis or Ornithosis

Parrot fever or chlamydiosis is caused by a small intracellular bacteria, Chlamydia psittaci, that lives within the respiratory system of birds.

A similar organism, which doesn’t seem to affect humans, is found in cats. Transmission is through inhalation of dust, dander and nasal secretions of infected birds – especially parrots and turkeys.

The flu-like illness that develops ranges from very mild to life-threatening. In rare instances the heart and liver become involved.

The disease is often misdiagnosed as influenza. When a correct diagnosis is made psittacosis responds well to antibiotics of the tetracycline class.
