Pneumocystis carinii

Pneumocystis carinii
The eukaryotic microorganism responsible for interstitial pneumonia in immunocompromised patients. The exact taxonomic position remains unclear, as the organism has morphologic similarities to protozoa but shares substantial 16S ribosomal RNA and mitochondrial DNA with some species of the Ascomycetes. P. carinii fails to grow on fungal culture media but takes up fungal stains, and infections from it respond to antiprotozoal as well as to some antifungal drugs. [G. pneuma, air, breathing, + kystis, bladder, pouch]

* * *

a species that formerly included all of the species in the genus, but is now limited to those infecting rats; the agent that infects humans has been reclassified as P. jiroveci.
