Definitions related to pneumocystis jiroveci pneumonia:
-
(pneumocystis pneumonia) A severe, progressive pneumonia caused by Pneumocystis jirovecii, which is usually seen in immunologically compromised individuals.NICHD Pediatric TerminologyU.S. National Cancer Institute, 2021
-
(pneumocystis pneumonia) Pneumonia resulting from infection with Pneumocystis jirovecii, frequently seen in the immunologically compromised, such as persons with AIDS, or steroid-treated individuals, the elderly, or premature or debilitated babies during their first three months. Patients may be only slightly febrile (or even afebrile), but are likely to be extremely weak, dyspneic, and cyanotic. This is a major cause of morbidity among patients with AIDS.NCI ThesaurusU.S. National Cancer Institute, 2021
-
(pneumocystis pneumonia) Pulmonary disease in humans occurring in immunodeficient or malnourished patients or infants, characterized by dyspnea, tachypnea, and hypoxemia; Pneumocystis pneumonia is a frequent opportunistic infection in AIDS; also found in other mammals where it is caused by related species of Pneumocystis.CRISP ThesaurusNational Institutes of Health, 2006
-
(pneumonia, pneumocystis) A pulmonary disease in humans occurring in immunodeficient or malnourished patients or infants, characterized by DYSPNEA, tachypnea, and HYPOXEMIA. Pneumocystis pneumonia is a frequently seen opportunistic infection in AIDS. It is caused by the fungus PNEUMOCYSTIS JIROVECII. The disease is also found in other MAMMALS where it is caused by related species of Pneumocystis.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
(pneumocystis jirovecii pneumonia) An opportunistic disease caused by invasion of unicellular fungus Pneumocystis jirovecii. Transmission of P. jirovecii cysts takes place through the airborne route, and usually, its presence in lungs is asymptomatic. However, people with impaired immunity, especially those with CD4+ T cell count below 200/microliter, are still at risk of the development of Pneumocystis pneumonia due to P. jirovecii invasion. Symptoms induced by this disease are not specific: progressive dyspnoea, non-productive cough, low-grade fever, arterial partial pressure of oxygen below 65 mmHg, and chest radiographs demonstrating bilateral, interstitial shadowing.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021

Pneumocystis jirovecii is a common cause of pneumonia in immunosuppressed patients, especially in those infected with human immunodeficiency virus (HIV) and in those receiving systemic corticosteroids. Symptoms include fever, dyspnea, and dry cough. Diagnosis requires demonstration of the organism in an induced sputum specimen or...Merck & Co., Inc., 2020

Pneumocystis jiroveci pneumonia (PJP), formerly known as Pneumocystis carinii pneumonia (PCP), is the most common opportunistic infection in persons with HIV infection. Pneumocystis first came to attention as a cause of interstitial pneumonia in severely malnourished and premature infants during World War II in Central and Eastern Europe.WebMD, 2019
-
Human pneumocystosis is caused by an infectious agent, which (after recent nomenclature and taxonomy revisions) is now classed as the fungus Pneumocystis jiroveci. The prevalence is unknown. Pneumocystis jiroveci is an opportunistic infectious agent, developing in immunosuppressed patients. It is an air-borne infection, localised to the...National Center for Advancing Translational Sciences
-
Pneumocystis pneumonia (PCP) is an infection of the lung caused by the fungal organism Pneumocystis jirovecii (formerly known as Pneumocystis carinii ). Typically, it causes clinical disease in severely immunocompromised patients, such as HIV-positive patients with CD4 cell counts <200 cells/microliter, bone marrow transplant patients,...Athenahealth, Inc., 2019
