Haematobium schistosomiasis in the squirrel monkey (Saimiri sciureus).

The squirrel monkey (Saimiri sciureus) accommodates Schistosoma haematobium moderately well. Adults occur in the major viscera but the extent of tissue egg deposits and associated pathology is variable. Pathologic involvement of the urogenital system occurs in a large proportion of hosts exposed to moderate to heavy infections, and bladder pathology is indicative of conditions associated with bladder carcinoma.
