| Pneumocystis carinii | <protozoa> A protozoon microorganism that is the causative agent of pneumocystis pneumonia in immunocompromised patients (e.g. With AIDS). It is most closely related to ustomycetous yeasts. See: pneumocystis carinii pneumonia (27 Sep 1997) |
| pneumocystis carinii infections | Infection with pneumocystis carinii, a fungus causing interstitial plasma cell pneumonia (pneumonia, pneumocystis carinii) and other infections in humans. Immunocompromised patients, especially those with aids, are particularly susceptible to these infections. Extrapulmonary sites are rare but seen occasionally. (12 Dec 1998) |
| pneumocystis carinii pneumonia | <chest medicine> A pneumonia caused by an infection with Pneumocystis carinii. Pneumocystis carinii grows rapidly in the lungs of patients with immunosuppression, particularly due to AIDS and is the leading AIDS-related cause of death. Pneumocystis carinii infection sometimes may occur elsewhere in the body (skin, eye, spleen, liver or heart). It is considered one of the diagnostic criteria for AIDS in an HIV positive individual.
