Sensitivity of P. falciparum, P. ovale, and P. vivax real-time assay. (A) Amplification (as duplicate) of P. falciparum sample dilutions containing 704 (Toto), 70 (1), 7 (2), and 0.7 (3) parasites/μl. (B) Plot of mean CT values from four replicates tested against the P. falciparum DNA inputs. The plot of CT values and DNA input fits a linear function (R2 = 0.952). (C) Amplification (as duplicate) of P. ovale sample dilutions containing 4620 (Toto), 462 (1), 46 (2), and 4 (3) parasites/μl. (D) Plot of mean CT values from four replicates tested against the P. ovale DNA inputs. The plot of the CT values and DNA input fits a linear function (R2 = 0.952). (E) Amplification (as duplicate) of P. vivax sample dilutions containing 15,000 (Toto), 1,500 (1), 150 (2), 15 (3), and 1.5 (4) parasites/μl. (F) Plot of mean CT values from five replicates tested against P. vivax DNA inputs. The plot of CT values and DNA input fits a linear function (R2 = 0.969).
