L-Arg pretreatment inhibits formation of zygotes and ookinetes

Mice	Number of zygotes (Mean ± SEM)	Number of ookinetes (Mean ± SEM)
Normal infection	65.5 ± 6.4	20.0 ± 2.8
L-Arg pretreatment	5.0 ± 4.2##	2.5 ± 2.1#

Note: # and ## indicate significant difference between D-Arg pretreated control (Normal infection) and L-Arg pretreated mice (L-Arg treatment) at P < 0.05 and P <0.01 (t-test), respectively
