FIG. 1.

Infection of rhesus macaques with S. mansoni. Eight animals were percutaneously exposed to 500 cercariae. (A) Egg counts in stool samples collected from the S. mansoni-inoculated animals. Data represent the running average of three consecutive values. SEM, standard error of the mean. (B) Percentage of eosinophils in SHIV-1157ip-infected rhesus monkeys with and without concurrent schistosomiasis. In coinfected animals, the percentage of eosinophils rose as a function of time of infection.
