Psittacosis (Chlamydia Psittaci): Symptoms, Causes & Treatment

The bacteria Chlamydia psittaci causes an infection known as psittacosis. Unlike a similar sounding sexually transmitted disease, the C. psittaci bacteria is transmitted from birds and their droppings. While very rare, the disease can be dangerous if not promptly treated.

Pulmonary Symptoms

• Psittacosis can cause blood-tinged sputum, a dry cough and shortness of breath.

Neurological Symptoms

• Infection by Chlamydia psittaci may cause headache and fatigue.

General Symptoms

• Fever, chills and muscle aches may present with psittacosis.

Severe Symptoms

• Endocarditis, hepatitis and severe pneumonia may occasionally occur with untreated psittacosis.

Incubation

• Symptoms generally start to appear 5 to 19 days after exposure. Anyone who works with birds and exhibits symptoms should seek medical care to confirm the diagnosis.
