Pneumocystis pneumonia (PCP), also known as Pneumocystis jirovecii pneumonia (PJP), is a form of pneumonia that is caused by the yeast-like fungus Pneumocystis jirovecii. [ 3 ] [ 4 ] Pneumocystis specimens are commonly found in the lungs of healthy people although it is usually not a cause for disease. [ 5 ]
Pneumocystis jirovecii (previously P. carinii) is a yeast-like fungus of the genus Pneumocystis. The causative organism of Pneumocystis pneumonia, it is an important human pathogen, particularly among immunocompromised hosts. Prior to its discovery as a human-specific pathogen, P. jirovecii was known as P. carinii.
Pneumocystosis is a fungal infection that most often presents as Pneumocystis pneumonia in people with HIV/AIDS or poor immunity. [1] [7] It usually causes cough, difficulty breathing and fever, and can lead to respiratory failure. [4]
Fungal pneumonia is an infection of the lungs by fungi. It can be caused by either endemic or opportunistic fungi or a combination of both. Case mortality in fungal pneumonias can be as high as 90% in immunocompromised patients, [ 1 ] [ 2 ] though immunocompetent patients generally respond well to anti-fungal therapy.
Since pneumonia can take a dangerous turn, it's important to know the earliest signs of it. Dr. Zweig says that, typically, pneumonia starts as a regular viral upper respiratory infection.
“Fungal pneumonias are unusual in healthy hosts,” Dr. Russo says. “White lung” pneumonia treatment In terms of the outbreak in Ohio, it seems to be driven by Streptococcus pneumoniae ...
Fungal pneumonia is uncommon, but occurs more commonly in individuals with weakened immune systems due to AIDS, immunosuppressive drugs, or other medical problems. [22] [48] It is most often caused by Histoplasma capsulatum, Blastomyces, Cryptococcus neoformans, Pneumocystis jiroveci (pneumocystis pneumonia, or PCP), and Coccidioides immitis.
It is used widely as a screen for fungal organisms. It is particularly useful in staining carbohydrates. It can be used to identify the yeast-like fungus Pneumocystis jiroveci, [1] which causes a form of pneumonia called Pneumocystis pneumonia (PCP) or pneumocystosis. The cell walls of these organisms are outlined by the brown to black stain.
