  Pneumocystis - Wikipedia, the free encyclopedia
Pneumocystis is a genus of fungi which can be pathogenic in mammals.
Pneumocystis species can cause pneumonia in immunocompromised individuals; in humans, those with AIDS are particularly susceptible, with P.
Also known as pneumocystis pneumonia (PCP), the disease attacks the interstitial, fibrous tissue of the lungs, with marked thickening of the alveolar septa and alveoli and leading to significant hypoxia which can be fatal if not treated aggressively.

 The Body: Update: Pneumocystis carinii Pneumonia
Although the first-line therapy for pneumocystis, TMP-SMX, will also treat many bacterial pathogens, the dosage and duration of therapy used to treat PCP are higher and longer than those necessary to treat bacterial pneumonia.
Pneumocystis is infrequent in patients receiving TMP-SMX, and when such patients present with respiratory symptoms the clinician should make every effort to find an alternative diagnosis for those symptoms before embarking on a course of empiric treatment.
Consequently, in a patient whose symptoms suggest pneumocystis but whose induced sputum examination for PCP is negative, bronchoscopy is necessary -- to either rule out the diagnosis of PCP, so that potentially toxic empiric therapy can be discontinued, or to rule in the diagnosis of PCP, so that empiric therapy may be appropriately continued.
