Pneumocystis jirovecii on pärmilaadne seen, mis on laialt levinud tervete inimeste kopsudes, kuid põhjustab kopsuinfektsiooni (pneumotsüsti-pneumoonia ehk PCP) nõrgenenud immuunsüsteemiga inimestel ja enneaegsetel lastel.
Algselt peeti Pneumocystis patogeeni algloomaks ning tunti nime all Pneumocystis carinii. Aastal 1976 leiti, et tegemist on inimese-spetsiifilise liigiga ning eristamaks seda teistest Pneumocystis liikidest, omistati talle nimetus Pneumocystis jiroveci. Pärast DNA uuringuid tehti aga kindlaks, et tegemist on seenega ning nimetus muudeti vastavalt Rahvusvahelise botaanilise nomenklatuurikoodeksi järgi (ICBN): Pneumocystis jirovecii.
Kuna Pneumocystis jirovecii’t pole võimalik kultuuris kasvatada, on molekulaarne tuvastamine oluline.
Uuritav materjal, selle võtmine, saatmine ja säilitamine
Analüüsi valik sõltub uuritavast proovimaterjalist: rögast saab teha Pneumocystis jirovecii DNA analüüsi, ülejäänud proovimaterjalidest Pneumocystis jirovecii DNA QN analüüsi.
