PATHOGENESIS Traditionally, CAP has been viewed as an infection of the lung parenchyma, primarily caused by bacterial or viral respiratory pathogens.
What is pneumonia pathophysiology?
Most pneumonia occurs when a breakdown in your body’s natural defenses allows germs to invade and multiply within your lungs. To destroy the attacking organisms, white blood cells rapidly accumulate. Along with bacteria and fungi, they fill the air sacs within your lungs (alveoli).
How many pathology forms of pneumonia are found?
The histopathology in pneumonia can be broadly studied under 2 main headings: bronchopneumonia/lobular pneumonia or lobar pneumonia. Lobar pneumonia is diffuse consolidation involving the entire lobe of the lung.
What are the four pathological stages of pneumonia?
Stage 1: Congestion. Stage 2: Red hepatization. Stage 3: Grey hepatization. Stage 4: Resolution.
What is a community-acquired pneumonia?
In community-acquired pneumonia (CAP), you get infected in a community setting. It doesn’t happen in a hospital, nursing home, or other healthcare center. Your lungs are part of your respiratory system. This system supplies fresh oxygen to your blood and removes carbon dioxide, a waste product.

What is the epidemiology of community-acquired pneumonia?
The estimated worldwide incidence of community-acquired pneumonia varies between 1.5 to 14 cases per 1000 person-years, and this is affected by geography, season, and population characteristics. In the United States, the annual incidence is 24.8 cases per 10,000 adults with higher rates as age increases.
Which is the most common organism causing community-acquired pneumonia?
Community-acquired pneumonia is defined as pneumonia that is acquired outside the hospital. The most commonly identified pathogens are Streptococcus pneumoniae, Haemophilus influenzae, atypical bacteria (ie, Chlamydia pneumoniae, Mycoplasma pneumoniae, Legionella species), and viruses.
What are the 2 types of pneumonia?
The main types of pneumonia are:
- Bacterial pneumonia. This type is caused by various bacteria.
- Viral pneumonia. This type is caused by various viruses, including the flu (influenza), and is responsible for about one-third of all pneumonia cases.
- Mycoplasma pneumonia.
- Other pneumonias.
How do you classify community-acquired pneumonia?
Mild, moderate or severe pneumonia To be able to provide the right treatment, doctors also classify community-acquired pneumonia as mild, moderate or severe. They take the risk of complications into account as well. does not have any other severe medical conditions.
What should I include in a pathophysiology?

What is the most commonly identified cause of community-acquired pneumonia?
What are the most common causes of community acquired pneumonia?
Pneumonia is a common illness that affects millions of people each year in the United States. Germs called bacteria, viruses, and fungi may cause pneumonia. In adults, bacteria are the most common cause of pneumonia. Ways you can get pneumonia include: Bacteria and viruses living in your nose, sinuses, or mouth may spread to your lungs.
What is the difference between hospital and community acquired pneumonia?
Pneumonia is generally classified into two types – community acquired pneumonia and nosocomial (hospital acquired) pneumonia. In the former case the causative pathogens are primarily viruses and gram positive bacteria while in the later case the causative pathogens are primarily gram negative organisms.
How to treat community acquired pneumonia?
