^aThese data are representative of two experiments with similar results.

^bGeometric mean.

^cInfectivity if expressed as the percentage of mean oocysts per gut relative to that of the control group.

^dNumber of mosquitoes infected/total number of mosquitoes dissected.

^eP values were determined by the Mann-Whitney U test.

^fNegative control.

^gPositive control.

^hIC, isotype control.
