Pneumocystis Pneumonia

PNEUMONIA caused by a species of the genus of PROTOZOA, a parasitic micro-organism. Pneumocystis carinii causes an opportunistic infection in the lung which is dangerous to people whose immune system is impaired (see IMMUNITY), thus reducing their resistance to infections. People with AIDS/HIV or LEUKAEMIA have impaired immune systems and P. carinii is a major cause of death in the former. Fever, dry cough and breathlessness are among the symptoms; treatment is with high doses of antibiotic drugs such as CO-TRIMOXAZOLE or PENTAMIDINE.... pneumocystis pneumonia
