Atypical bacteria causing pneumonia are Coxiella burnetii, Chlamydophila pneumoniae (), Mycoplasma pneumoniae (), and Legionella pneumophila.. The term "atypical" does not relate to how commonly these organisms cause pneumonia, how well it responds to common antibiotics or how typical the symptoms are; it refers instead to the fact that these organisms have atypical or absent cell wall ...
Pneumococcal pneumonia is a type of bacterial pneumonia that is caused by Streptococcus pneumoniae (pneumococcus). [1] It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia, and one of the common types of pneumococcal infection. The estimated number of Americans with pneumococcal ...
Occupational exposures to carcinogens cause 9–15% of lung cancer. [71] A prominent example is asbestos, which causes lung cancer either directly or indirectly by inflaming the lung. [71] Exposure to all commercially available forms of asbestos increases cancer risk, and cancer risk increases with time of exposure. [71]
Side effects on the lungs can be very varied, and can include signs and symptoms that are either clinical, or radiological (i.e., seen on chest X-ray or CT), or both.They can include lung inflammation (pneumonitis), secondary (in this context, indirectly caused) lung infection (), lung fibrosis, organising pneumonia (bronchiolitis obliterans organising pneumonia, BOOP), ARDS (acute respiratory ...
Pneumonia is a common respiratory infection, [2] affecting approximately 450 million people a year and occurring in all parts of the world. [3] It is a major cause of death among all age groups, resulting in 1.4 million deaths in 2010 (7% of the world's yearly total) and 3.0 million deaths in 2016 (the 4th leading cause of death in the world).
The bacterium Streptococcus pneumoniae, a common cause of pneumonia, imaged by an electron microscope. Pneumonia is due to infections caused primarily by bacteria or viruses and less commonly by fungi and parasites. Although more than 100 strains of infectious agents have been identified, only a few are responsible for the majority of cases.
Bacteria involved in causing and treating cancers. Cancer bacteria are bacteria infectious organisms that are known or suspected to cause cancer. [1] While cancer-associated bacteria have long been considered to be opportunistic (i.e., infecting healthy tissues after cancer has already established itself), there is some evidence that bacteria may be directly carcinogenic.
[citation needed] In the case of pneumonitis, it is more difficult for this exchange of oxygen to occur since irritants have caused inflammation of the alveoli. [3] Due to the lack of a definitive determination of a single irritant causing pneumonitis, there are several possible causes. [3] Viral infection. Measles can cause severe pneumonitis ...
