PY - 2011 T2 - Rudolph's Pediatrics, 22e AB - Pneumocystis pneumonia (PCP) occurs almost exclusively in the severely immunocompromised host, especially patients with congenital immunodeficiency diseases, AIDS, and cancer, and those who have had organ transplantation. Once pneumonia is apparent, the fatality rate is near 100% if untreated. Effective therapeutic and prophylactic drugs are available. The causative agent is a protozoan-like fungus known for the past century as Pneumocystis carinii. Recently, the term Pneumocystis jirovecii has been proposed for the organism found in humans,1 but acceptance has not been universal.2 SN - PB - The McGraw-Hill Companies CY - New York, NY Y2 - 2024/03/29 UR - accesspediatrics.mhmedical.com/content.aspx?aid=7032071 ER -
