A cytotoxicity assay for evaluation of candidate anti-Pneumocystis carinii agents.
A series of over 60 agents representing several different classes of compounds were evaluated for their effects on the ATP pools of Pneumocystis carinii populations derived from immunosuppressed rats. A cytotoxicity assay based on an ATP-driven bioluminescent reaction was used to determine the concentration of agent which decreased the P. carinii ATP pools by 50% versus untreated controls (IC50...
متن کاملBiological profile and response to anti-pneumocystis agents of Pneumocystis carinii in cell culture.
Although the growth characteristics of Pneumocystis carinii have been described in several cell culture systems, the response of this organism to the drugs of choice, trimethoprim-sulfamethoxazole and pentamidine isethionate, have not been described in vitro. The effect of various concentrations of drugs against P. carinii on the growth of this potentially hazardous opportunistic organism as we...
متن کاملDevelopment 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...
متن کاملDevelopment and evaluation of a molecular viability assay for Pneumocystis carinii.
Despite recent declines in incidence, Pneumocystis carinii pneumonia (PCP) remains the most commonly occurring opportunistic illness among persons with AIDS in the United States. While P. carinii DNA has been detected in patient respiratory specimens and in air samples collected from various indoor environments housing PCP patients, the viability of these organisms is unknown. For this reason, ...
متن کاملMouse Anti-Pneumocystis carinii Monoclonal Antibody
carinii. Specificity: QSP228 antibody reacts specifically with P. carinii pneumonia, staining especially cysts present in biopsy material, bronchial lavage and induced sputum samples. For bronchial lavage and induced sputum samples pretreatment of samples with 0.3% dithiothreitol or sputolysin is recommended. In Western blotting analysis the antibody identifies an antigen of 93 kD of P. carinii...
