Experimental infection with Schistosoma intercalatum (Fisher, 1934) in the chimpanzee (pan troglodytes) and the gibbon (Hylobates lar).

Two young chimpanzees (Pan troglodytes) and two adult gibbons (Hylobates lar), each exposed to 1,000 cercariae of Schistosoma intercalatum (Cameroon), were examined at 79 and 82 wk and 61 and 69 wk, respectively, post-infection. Based upon worn returns and tissue egg deposits, these primates can be employed as hosts for experimental schistosomiasis intercalata. However, no histopathology was detected in the urogenital system.
