چکیده

The susceptibility of Pneumocystis carinii to artemisinin (qinghaosu) was determined in short-term primary culture. In untreated cultures, trophozoites increased an average of fivefold over 4 days. Inhibition of parasite growth in cultures treated with artemisinin at concentrations as low as 0.5 microM was seen. In contrast, artemisinin concentrations up to 100 microM had no effect on feeder layer cells.

Growth of Pneumocystis Carinii in Axenic Culture

SUMMARY In this research, which was done for two years, we investigated various liquid and solid media without feeder ceells, for the ability to support growth of P. carinii. Data obtained from counting the organisms nuclei showed that, addition of Cyclo­heximide, penicillin, & streptomycin to neopeptone­N-Acetyle Glucoseamine (N.P.G. medium) can provides growth requirements of organism in its...

Development of a rapid real-time PCR assay for quantitation of Pneumocystis carinii f. sp. carinii.

A method for reliable quantification of Pneumocystis carinii in research models of P. carinii pneumonia (PCP) that is more convenient and reproducible than microscopic enumeration of organisms would greatly facilitate investigations of this organism. We developed a rapid quantitative touchdown (QTD) PCR assay for detecting P. carinii f. sp. carinii, the subspecies of P. carinii commonly used in...

Background & Aims: Pneumocystis carinii is an opportunist extracellular microorganism. The body can defend itself against it in natural conditions. But it can cause an infection in immunodificient conditions such as HIV, Hodgkins and other immunosuppressed diseases. The aim of this study was to apply a comparison of different staining methods such as Methenamine silver, Giemsa, Gram - Weigert, ...
