Pneumonia caused by P. jirovecii (formerly called P. carinii ) is an opportunistic infection most commonly associated with the human immunodeficiency virus (HIV). However, individuals who are immunosuppressed for other reasons, such as those undergoing treatment for organ transplantation or connective tissue diseases with steroids and other immunosuppressants also are at risk of PJP.
