Pneumonia, often called bronchopneumonia or bronchial pneumonia, can be a serious, even life-threatening, complication of COPD. When you have a chronic disease, your immune system is already compromised, making it harder to fight infections. Add to that the weakened airways and lung tissue that is part of COPD, and it is obvious how much of a threat a respiratory infection like pneumonia can be to someone who has COPD.
What Is Pneumonia?
Pneumonia is a respiratory infection that leads to inflammation and swelling in the bronchial tubes, known as bronchioles, and also tiny cells or airsacs at the end of the airways, called alveoli. Because COPD already causes similar issues, pneumonia results in an acute exacerbation of COPD.
What does that mean? Well, it means that there is an acute deterioration of respiratory symptoms. In particular, there will be increased breathlessness and cough, and an increase in the amount of sputum, as well as a change in the quality of t...

<p>Pneumonia is a type of pneumonitis—an inflammation of the lungs that may be caused by the inhalation of irritating gases or particles or by an infection. When the inflammation is caused by an infectious microorganism, the term pneumonia is used.</p>
<p>The lungs have a complex system of defense: frequent branching and narrowing of the bronchial passages make it difficult for invaders to penetrate the lungs deeply; millions of tiny hairs, or cilia, in the bronchial lining constantly sweep particles out of the airways; the cough reflex forces irritating substances out of the lungs at high speed; and white blood cells, known as macrophages or scavenger cells, engulf and destroy many infectious agents.</p>
<p>Pneumonia is common, and can be a complication from a lingering cold or bout with influenza or bronchitis. Nearly half of community-acquired pneumonia cases are believed t...
Psittacosis is an infection caused by Chlamydia psittaci, a type of bacteria found in the droppings of birds. Birds spread the infection to humans.
Ornithosis; Chlamydia psittaci
Causes, incidence, and risk factors
Psittacosis is a rare disease: 100 - 200 cases are reported each year in the United States.
Bird owners, pet shop employees, persons who work in poultry processing plants, and veterinarians are at increased risk for this infection. Typical birds involved are parrots, parakeets, and budgerigars, although other birds have also caused the disease.
