Pneumonia has many causes, but most common are bacteria and viruses usually occur in the environment. Usually your body keeps these germs from invading your lungs. Sometimes, however, reliable embryo may violate your protection, regardless of your overall health. Germs that cause pneumonia in healthy people is usually not the same that cause pneumonia in hospitals and other health care. In addition, bacteria that can infect the lungs by inhaling foreign substances (inhalation or aspiration pneumonia), differ from strattera price those that cause the more common types of pneumonia. The same goes for germs that cause pneumonia in people with weakened immune response. Community acquired pneumonia When you get pneumonia from exposure to germs you encounter during your normal life, it is called pneumonia. These germs usually cause normal light form of pneumonia, doctors can treat easily. Microbes are responsible for most pneumonia: bacteria.
Bacterium that causes most cases of pneumonia is the pneumococcus. Other possible agents are Staphylococcus aureus, Haemophilus influenzae and Klebsiella pneumonia. It is not uncommon to pneumonia caused by more than one type of bacteria at the time. Methicillin-resistant staphylococcus gold (MRSA), antibiotic-resistant bacteria once only in health care, now causes skin infections and pneumonia in the community, too. Bacteria organisms. Mycoplasma pneumonia is a tiny organism that normally produces a mild signs and symptoms than other types of pneumonia. Walking pneumonia, the term used to describe pneumonia that is not serious enough to require bed rest may result from Mycoplasma pneumonia. Lehionelly and Chlamydia pneumonia pneumonia two other microbes that are neither bacteria nor viruses. Viruses. Some of these types of viruses that cause flu and colds can cause pneumonia. Although most cases of viral pneumonia and a decision in time with rest and fluids, viral pneumonia caused by influenza viruses can become very serious. Viral pneumonia can create a simple environment for the invasion of bacteria, causing the second infection. Fungi and parasites. Other less common causes of pneumonia include fungi, parasites and bacteria that cause tuberculosis. In most cases, parasitic pneumonia occur in people who were living in developing countries. Medical pneumonia heavy, difficult to treat bacterial pneumonia is a serious problem in health care facilities not only hospitals and nursing homes and dialysis centers and ambulatory infusion, where people regularly receiving chemotherapy of cancer and other intravenous drugs. Medical pneumonia sometimes caused by strains of pneumococcus and Haemophilus influenzae, which also occur in society. But the list of microbes that cause nosocomial pneumonia does not stop there. In hospitals, bacteria can quickly become resistant to antibiotics, standard, so drug-resistant germs are found more often. Resistant bacteria such as Pseudomonas aeruginosa and MRSA to make treatment difficult. People on breathing machines (ventilators), often used in hospital intensive care units are particularly vulnerable. With so many possible culprits, and high probability of resistant strains, the problem in hospitals is to identify the causative agent and determine which antibiotics will work against him. Inhalation or aspiration pneumonia Aspiration pneumonia occurs when you breathe foreign substances into the lungs. This can happen if vomit while sleeping or unconscious and breathing in some of the contents of the stomach. Difficulty swallowing that occurs with diseases such as amyotrophic lateral sclerosis (ALS), Parkinson's disease and stroke, and sometimes leads to aspiration pneumonia. Opportunistic viral, bacterial and fungal pneumonia
These types of pneumonia attack people with weakened immune systems. The organisms are not harmful to human health can be dangerous for people who have had organ transplants and people with AIDS and other conditions that weaken the immune system. Drugs that suppress the immune system, such as corticosteroids or chemotherapy, and may put you at risk of opportunistic pneumonia. 1998-2012 Mayo Foundation for Medical Education and Research (MFMER). .
