Real-time PCR for quantitative detection of Toxoplasma gondii.
The protozoan Toxoplasma gondii is one of the most common infectious pathogenic parasites and can cause severe medical complications in infants and immunocompromised individuals. We report here the development of a real-time PCR-based assay for the detection of T. gondii. Oligonucleotide primers and a fluorescence-labeled TaqMan probe were designed to amplify the T. gondii B1 gene. After 40 PCR...
متن کاملAdapting a conventional PCR assay for Toxoplasma gondii detection to real-time quantitative PCR including a competitive internal control.
We have developed a quantitative PCR assay (LightCycler* using the pair of primers JW58 and JW59 for the detection of the 35-fold repeated B gene of oxoplasma gondii. This real-time PCR, using fluorescence resonance energy transfert (FRET) hybridization probes, allows the quantification of . gondii with several technical requirements not previously described: i) an internal amplification contro...
متن کاملDetection of Toxoplasma gondii oocysts in water sample concentrates by real-time PCR.
PCR techniques in combination with conventional parasite concentration procedures have potential for the sensitive and specific detection of Toxoplasma gondii oocysts in water. Three real-time PCR assays based on the B1 gene and a 529-bp repetitive element were analyzed for the detection of T. gondii tachyzoites and oocysts. Lower sensitivity and specificity were obtained with the B1 gene-based...
متن کاملComparison between two real-time PCR assays and a nested-PCR for the detection of Toxoplasma gondii.
BACKGROUND AND AIM OF THE WORK In recent years, the diagnosis of toxoplasmosis has been improved by Real-time PCR assays. In this study we compared the performances of two Real-time PCRs (FRET and TaqMan protocols) already described in the literature, and one nested-PCR, currently used in our laboratory for the molecular diagnosis of toxoplasmosis. METHODS We evaluated the sensitivity and the...
