Pneumocystis jirovecii

Pneumocystis jirovecii (pronounced: new-mo-sis-tis ji-ro-ve-see-eye) is a yeast-like fungus that causes Pneumocystis pneumonia (PCP), a severe lung infection, especially in people with weakened immune systems.

Etymology

The organism was named in honor of Czech parasitologist Otto Jirovec, who first identified it in the lungs of babies who died from premature birth and malnutrition during World War II. The species name "jirovecii" was proposed in 1976 to distinguish the human pathogen from other species in the genus Pneumocystis.
