Quantitative detection of Tropheryma whipplei DNA by real-time PCR.
Over the past decade, PCR-based methodologies have been introduced to complement or even replace histopathologic study of biopsy specimens for the diagnosis of Whipple’s disease (12). However, positive PCR results have been reported on testing small-bowel and saliva specimens from asymptomatic patients (3, 4, 11). Although these results have not been independently confirmed (8), they have nonet...
متن کاملDetection of Tropheryma whipplei DNA in clinical specimens by LightCycler real-time PCR.
A real-time PCR method using the LightCycler (Roche Applied Science, Indianapolis, IN) was compared to a conventional PCR assay for the detection of Tropheryma whipplei in 321 clinical specimens. The LightCycler method had sensitivity and specificity comparable to the conventional method but required considerably less labor and time (3 h versus 3 to 5 days).
متن کاملDetection of Tropheryma whipplei DNA in feces by PCR using a target capture method.
Whipple's disease is a rare multisystemic bacterial infection with variable clinical manifestations. For decades, the laboratory diagnosis was based on the demonstration of periodic acid Schiff-positive inclusions in macrophages of gastrointestinal biopsies. PCR has improved the diagnosis of Whipple's disease due to its increased sensitivity compared to histopathological analysis. To avoid inva...
متن کاملDetection of human cytomegalovirus DNA by real-time quantitative PCR.
A real-time PCR assay was developed to quantify human cytomegalovirus (CMV) DNA. This assay was used to demonstrate a higher CMV DNA load in plasma of bone marrow transplant patients than in that of blood donors. The CMV load was higher in CMV antigen-positive patients than in antigen-negative patients.
متن کاملReal-Time Quantitative PCR for Detection Cell Free Fetal DNA
Basically, diagnosis inherited diseases in gestation is very important. But amplication of the progress in early stage of pregnance is the serious and great aim for rapid application of risk assesment for both and fetus. Fetal genetic tissues collected through techniques such as amniocentesis and chorionic villus sampling (CVS) for prenatal diagnosis of fetal genetic diseases. These procedures ...
