Substantial Contribution of Submicroscopical Plasmodium falciparum Gametocyte Carriage to the Infectious Reservoir in an Area of Seasonal Transmission
Figure 1
The relationship between Pfs25 QT-NASBA gametocyte density and the proportion of infected mosquitoes in membrane feeding experiments.
The solid line indicates the best fitted line (Y = 0.0176Ln(X) + 0.0187; R2 = 0.153). The dashed line indicates the estimated microscopic threshold for gametocyte detection, 8 gametocytes/µL, when screening 100 high power fields (i.e. ∼1000 white blood cells).
