Pneumonia has many possible causes but the most common bacteria and viruses found in the environment. In general, the body is to keep these germs invade the lung. Sometimes, however, a solid element may be in violation of our defenses, regardless of your overall health.
The germs that cause pneumonia in healthy people are generally not the same as those that cause pneumonia in hospitals and health centers. Similarly, the germs that can infect the lungs if inhaled foreign material (by inhalation or aspiration pneumonia) differ from those that cause the most common types of pneumonia. The same is true of the germs that cause pneumonia in people with weak immune response.
Community-acquired pneumonia
When you get pneumonia from contact with germs you encounter during your normal routine, it is called community-acquired pneumonia. These common bacteria generally cause a mild form of pneumonia that doctors can easily handle. The microbes responsible for community-acquired pneumonia the most are:
Bacteria. The bacterium that causes most cases of community-acquired pneumonia is Streptococcus pneumoniae. Other potential agents include Staphylococcus aureus, Haemophilus influenzae and Klebsiella pneumoniae. It is not unusual to have more than one type of pneumonia caused by bacteria at a time. Methicillin-resistant Staphylococcus aureus (MRSA), antibiotic-resistant bacteria, once found only in health, are now causing skin infections and pneumonia in the Community, too.
The bacteria-like organisms. Mycoplasma pneumoniae is a small body, which usually produces less severe symptoms of pneumonia others. Walking pneumonia, which is used to describe pneumonia that is not severe enough to require rest, can be due to Mycoplasma pneumoniae. Legionella and Chlamydia pneumonia are two of the other bacteria that cause pneumonia, which are not bacteria or viruses.
Virus. Some of the same types of viruses that cause colds and flu can cause pneumonia. Although most cases are viral pneumonia are mild and resolve with time to rest and fluids, viral pneumonia caused by influenza viruses can become very serious. Viral pneumonia may set a first attack of environmental bacteria that cause infection in the second.
Fungi and parasites. Other less common causes of community-acquired pneumonia include fungi, parasites, and the germ that causes tuberculosis. Most of the parasitic pneumonia occur in people who live or have traveled to developing countries.
Health care for pneumonia
Severe, difficult to treat bacterial pneumonia is a major problem in health care facilities - not just hospitals and nursing homes, as well as kidney dialysis centers and outpatient infusion centers, where people regularly receiving cancer chemotherapy and other drugs intravenously.
Health care for pneumonia is sometimes caused by strains of Streptococcus pneumoniae and Haemophilus influenzae, which also appear in the community. But the list of organisms causing nosocomial pneumonia does not stop there. In hospitals, the bacteria can quickly become resistant to common antibiotics, so the drug-resistant germs are much more common. Resistant bacteria such as Pseudomonas aeruginosa and MRSA treatment to be difficult. People in the machinery of respiration (ventilation), often used in intensive care units in hospitals are particularly vulnerable.
With so many possible culprits, and a high probability of resistant strains, the problem of hospital is to identify the causative organism and determine which antibiotics against him.
Inhalation or aspiration pneumonia
Aspiration pneumonia is inhaled foreign bodies in their lungs. This can happen if you vomit while asleep or unconscious and breathing in some of the stomach contents. Difficulty swallowing, which occurs with diseases such as amyotrophic lateral sclerosis (ALS), Parkinson's disease and stroke, often leading to aspiration pneumonia.
Opportunistic viral pneumonia, bacterial and fungal
This type of pneumonia affects people with weakened immune systems. Organizations that are not harmful to healthy people can be dangerous for people who have had organ transplants and people with AIDS and other diseases that weaken the immune system. Drugs that suppress the immune system, such as corticosteroids or chemotherapy, can also put you at risk for opportunistic pneumonia.
