Figure 1From: Usefulness of real time PCR to quantify parasite load in serum samples from chronic Chagas disease patients DNA detection in serum, blood and T. cruzi samples by Real Time qPCR. Whole blood was spiked with Exo-IPC (1X) or T. cruzi cells (1 par. eq./ mL) before serum preparation. Results are expressed as the media of Threshold cycles (Ct) and represent the average from five replicate samples ± Standard deviation. *, ** p < 0.05.Back to article page
