The role of a nested polymerase chain reaction in the diagnosis of Pneumocystis carinii pneumonia.
Aim-To compare the techniques and results of a nested PCR and an immunofluorescence assay (IFA) for the detection of Pneumocystis carinii infection; to consider the role of the nested PCR in the diagnosis of P carinii pneumonia (PCP).Methods-Serial dilutions of two known P carinii positive samples were tested by IFA and PCR to determine their relative sensitivities. Seventy eight respiratory sa...
متن کاملRapid diagnosis of cytomegalovirus and Pneumocystis carinii pneumonia by using the capillary polymerase chain reaction.
We attempted to detect cytomegalovirus DNA (CMV-DNA) and Pneumocystis carinii DNA (P. carinii-DNA) in sputum samples of 18 hematological neoplasm patients with pneumonia, using rapid cycle DNA amplification. A thermal cycler based on recirculating hot air was used for rapid temperature control of 10-microliters samples in this glass capillary tubes. After a total amplification time of 15 min, t...
متن کاملDetection of Pneumocystis carinii DNA in sputum and bronchoalveolar lavage samples by polymerase chain reaction.
A polymerase chain reaction (PCR)-based assay was developed for the detection of Pneumocystis carinii DNA in induced sputum and bronchoscopic alveolar lavage samples. The primer pair was selected from the published sequence of the thymidylate synthase gene of P. carinii derived from infected rats. The amplified DNA fragment of 403 bp was detected by agarose gel electrophoresis and by Southern a...
متن کاملDiagnosis of Pneumocystis carinii pneumonia by bronchoalveolar lavage in AIDS patients. Comparison of Diff-Quik, fungifluor stain, direct immunofluorescence test and polymerase chain reaction.
OBJECTIVE To assess the sensitivity, specificity and accuracy of Diff-Quik, fungifluor stain, the direct immunofluorescence test (DIFT) and the polymerase chain reaction (PCR) in the diagnosis of Pneumocystis carinii pneumonia (PCP) in human immunodeficiency virus (HIV)-infected patients. STUDY DESIGN From December 1992 through November 1993, 112 bronchoalveolar lavage fluid (BALF) samples we...
متن کاملSensitive detection of Pneumocystis jirovecii DNA in gastric wash using nested polymerase chain reaction.
One hundred and five samples of gastric washes were obtained from 52 pediatric patients. Eleven of the 105 samples (10%) gave positive results using immunofluorescence antibody test (IFA) for Pneumocystis jirovecii. Single-step polymerase chain reaction (PCR) produced 13% (14 samples), whereas detection by nested PCR was increased to 65 samples (62%). Moderate agreement (kappa = 0.5) was found ...
