Pneumocystis is a eukaryotic unicellular microorganism with marked fungal affinities. All known life cycle stages of this parasite were observed in the lung of mammals. The cystic forms of this microorganism may be observed microscopically by using stains with affinity for the components of their relatively thick cell wall. However, about 100 years ago they were observed for the first time thanks to panoptic stains which do not stain their cell wall. Methanol-Giemsa technique as well as Giemsa-like rapid stainings are often used to reveal vegetative or cystic forms of this parasite on air dried smears of clinical or experimental samples. For many years, hypotheses on its life cycle, which remains unknown, were based on transmission electron microscopy (TEM) studies. However, only for the last years progresses in the quality of fixation for TEM led to a better understanding of the Pneumocystis cell structure. In this chapter, strategies to reveal Pneumocystis organisms in clinical or experimental specimens by using light microscopy, as well as techniques allowing a good preparation of parasitic samples for TEM, are given and shortly discussed.
