Pneumonia is an infection of the lungs. Almost all cases of pneumonia are caused by viral or bacterial infections. When pneumonia is first diagnosed, there often is no way to be sure if the infection is caused by a virus or bacteria.
In addition, a cough is frequently absent in children less than 2 months old. Pneumonia caused by Legionella may occur with abdominal pain, diarrheaor confusion.
Although there are over strains of infectious agents identified, only a few are responsible for the majority of the cases.
However, for those with TLR6 variants, the risk of getting Legionnaires' disease is increased. Bacterial pneumonia Cavitating pneumonia as seen on CT.
Pneumonia due to MRSA. Exposure to birds is associated with Chlamydia psittaci ; farm animals with Coxiella burnetti ; aspiration of stomach contents with anaerobic organisms; and cystic fibrosis with Pseudomonas aeruginosa and Staphylococcus aureus.
Fungal pneumonia Fungal pneumonia is uncommon, but occurs more commonly in individuals with weakened immune systems due to AIDSimmunosuppressive drugsor other medical problems.
Histoplasmosis is most common in the Mississippi River basinand coccidioidomycosis is most common in the Southwestern United States. Parasitic pneumonia A variety of parasites can affect the lungs, including Toxoplasma gondiiStrongyloides stercoralisAscaris lumbricoidesand Plasmodium malariae.
They include diffuse alveolar damageorganizing pneumonianonspecific interstitial pneumonialymphocytic interstitial pneumoniadesquamative interstitial pneumoniarespiratory bronchiolitis interstitial lung diseaseand usual interstitial pneumonia. The alveolus on the left is normal, whereas the one on the right is full of fluid from pneumonia.
Pneumonia frequently starts as an upper respiratory tract infection that moves into the lower respiratory tract. In the lower airways, reflexes of the glottisactions of complement proteins and immunoglobulins are important for protection. Micro aspiration of contaminated secretions can infect the lower airways and cause pneumonia.
The virulence of the organism, amount of the organisms to start an infection and body immune response against the infection all determines the progress of pneumonia. Respiratory syncytial virus is typically contracted when people touch contaminated objects and then they touch their eyes or nose.
Viruses also make the body more susceptible to bacterial infections; in this way, bacterial pneumonia can occur at the same time as viral pneumonia. Problems playing this file? Pneumonia is typically diagnosed based on a combination of physical signs and a chest X-ray.
Harsh breath sounds from the larger airways that are transmitted through the inflamed lung are termed bronchial breathing and are heard on auscultation with a stethoscope. Laterolateral chest radiograph can increase the diagnostic accuracy of lung consolidation and pleural effusion.
However, ultrasound requires specific skills to operate the machine and interpret the findings.Pneumonia is an inflammation of the lung parenchyma caused by various microorganisms, including bacteria, mycobacteria, fungi, and viruses.
Pneumonia is an inflammatory condition of the lung affecting primarily the small air sacs known as alveoli. Typically symptoms include some combination of productive or dry cough, chest pain, fever, and trouble breathing.
