  • Title: Morphological evaluation of Pneumocystis carinii after extraction from infected lung.
    Author: Soulez B, Dei-Cas E, Palluault F, Camus D.
    Journal: J Parasitol; 1991 Jun; 77(3):449-53. PubMed ID: 2040957.
    Abstract:
    Changes in Pneumocystis carinii induced by the extraction of the parasite from rabbit lung have been investigated. Samples obtained using 4 extraction methods were evaluated by light and transmission electron microscopy. Light microscopic evaluation was insufficient to give a measure of the P. carinii viability or to detect parasitic cellular alterations. In contrast, ultrastructural evaluation provided information on host and P. carinii cell integrity, which is a critical condition for viability. None of the tested methods was ideal. How thoroughly and in what shape P. carinii need to be extracted from tissues will determine which extraction technique is of best use.
