Guest guest Posted January 20, 2005 Report Share Posted January 20, 2005 Pneumocystis: Pneumocystis jiroveci (previously classified as Pneumocystis carinii), the _fungus_ (http://www.medterms.com/script/main/art.asp?articlekey=3527) that causes pneumocystis _pneumonia_ (http://www.medterms.com/script/main/art.asp?articlekey=450) (_PCP_ (http://www.medterms.com/script/main/art.asp?articlekey=4806) ). Pneumocystis jiroveci is found worldwide, in humans and animals. Serologic evidence indicates that most healthy children have been exposed to it by age 3 to 4. Pneumocystis _pneumonia_ (http://www.medterms.com/script/main/art.asp?articlekey=450) (PCP) occurs in immunosuppressed individuals and in premature, malnourished infants. The symptoms of Pneumocystis pneumonia (PCP) include _dyspnea_ (http://www.medterms.com/script/main/art.asp?articlekey=3145) (difficulty breathing), nonproductive _cough_ (http://www.medterms.com/script/main/art.asp?articlekey=33174#) , and fever. Chest X-rays show infiltrates in both lungs. Typically, in untreated PCP, increasing _pulmonary_ (http://www.medterms.com/script/main/art.asp?articlekey=5123) involvement leads to death. Pneumocystosis is one of the most common infections in immunosuppressed patients with AIDS. P.jiroveci: the infection has a world-wide distribution and the transmission seems to occur by airborne route. The organims that causes human pneumocystosis is now named Pneumocystis jiroveci * Frenkel 1999, in honor of the Czech parasitologist Otto Jirovec. The organism is now considered a fungus, based on nucelic acid and biochemical analysis; nevertheless, on the basis of morpholocic and biologic characterisitcs it is included in the atlas of medical parasitology Quote Link to comment Share on other sites More sharing options...
