Schistosome parasite load for sporozoite and blood-stage malaria infection. Egg counts were determined microscopically from processed stool samples collected weekly until egg counts reach zero for a minimum of two consecutive weeks. The graph shows the average number of eggs per gram of stool determined for the four macaques that were exposed to malaria through mosquito bites (◆) and the average number of eggs per gram of stool determined for the four macaques exposed to malaria through blood-stage parasites (●). The difference between schistosome parasite load of the two groups over the course of the schistosomiasis infection is not statistically significant (P = 0.20).
