Get A Second OpinionWhat is Psittacosis?
Psittacosis is an infectious disease caused by the bacterium Chlamydia psittaci. This bacterium is often found in birds, especially parrots, pigeons, and poultry. Humans can become infected by inhaling dust from dried bird droppings or secretions from infected birds.
Types of Psittacosis
There is only one main type of psittacosis, but it can affect different species of birds and can be transmitted to humans. The bacterium can be found in a variety of birds, including:
- Parrots
- Pigeons
- Poultry (chickens, ducks, turkeys)
- Canaries
- Parakeets
Causes of Psittacosis
Psittacosis is caused by the Chlamydia psittaci bacterium. Birds can carry this bacterium without showing any symptoms, and it can be spread through their droppings, feathers, and respiratory secretions. Humans typically contract the disease by inhaling dust contaminated with the bacterium.
Symptoms of Psittacosis
The symptoms of psittacosis in humans can vary widely. Some people may experience mild flu-like symptoms, while others may develop severe pneumonia. Common symptoms include:
- Fever
- Chills
- Headache
- Muscle aches
- Dry cough
- Shortness of breath
- Chest pain
- Fatigue
Psittacosis Rash
In some cases, a rash may develop. This rash is usually pink and blotchy and can appear on the face, chest, and abdomen. It is not very common but can occur in severe cases of the disease.
Diagnosis of Psittacosis
Diagnosing psittacosis can be challenging because its symptoms are similar to those of other respiratory illnesses. To diagnose psittacosis, a healthcare provider may use several methods:
Medical History and Physical Exam
The doctor will ask about your symptoms, any recent contact with birds, and your medical history. They will also perform a physical exam to check for signs of the disease.
Laboratory Tests
Several laboratory tests can help diagnose psittacosis, including:
- Blood tests to detect antibodies against Chlamydia psittaci
- Polymerase chain reaction (PCR) tests to detect bacterial DNA
- Chest X-rays to check for pneumonia
Treatment Options for Psittacosis
Psittacosis is treated with antibiotics. Early diagnosis and treatment are essential to prevent complications. The most commonly used antibiotics are:
Tetracyclines
Tetracyclines, such as doxycycline, are the first-line treatment for psittacosis. They are usually taken for 10-14 days. Tetracyclines are highly effective in treating the infection and alleviating symptoms.
Macrolides
Macrolides, such as azithromycin, may be used in patients who cannot take tetracyclines. These antibiotics are also effective in treating psittacosis.
Supportive Care
In addition to antibiotics, supportive care may be necessary for severe cases. This can include:
- Oxygen therapy for breathing difficulties
- Pain relievers and fever reducers
- Rest and hydration
Prevention of Psittacosis
Preventing psittacosis involves reducing the risk of exposure to the Chlamydia psittaci bacterium. Here are some tips to help prevent the spread of the disease:
Bird Owners
- Clean bird cages regularly and use protective equipment like masks and gloves.
- Avoid overcrowding birds in cages.
- Take birds to the vet for regular check-ups.
Poultry Workers
- Follow hygiene and safety guidelines when handling birds.
- Use protective clothing and equipment.
- Ensure proper ventilation in areas where birds are kept.
General Public
- Avoid close contact with birds if you are not a bird owner or poultry worker.
- Wash your hands thoroughly after handling birds or cleaning their cages.

Book an AppointmentComplications of Psittacosis
If left untreated, psittacosis can lead to severe complications, including:
- Pneumonia
- Endocarditis (inflammation of the heart lining)
- Hepatitis (inflammation of the liver)
- Encephalitis (inflammation of the brain)
Early diagnosis and treatment are crucial to prevent these complications.
