Parasites of man in remote areas of Central and South Sulawesi, Indonesia

A biomedical survey was conducted in 10 villages in remote, high mountain valleys of Central and South Sulawesi, Indonesia to learn whether Oriental schistosomiasis was endemic and to determine the prevalences of other intestinal parasites, malaria and filariasis in those areas. Although persons with Oriental schistosomiasis were found in three villages of South Sulawesi, follow-up inquiries revealed that these had recently migrated from a known schistosomiasis area in Central Sulawesi. Other intestinal parasites diagnosed were Ascaris lumbricoides (14%), Trichuris trichiura (7%), hookworm (68%), Entamoeba histolytica (3%), Entamoeba coli (17%), and Giardia lamblia (5%). Enterobius vermicularis, Strongyloides stercoralis, Trichostrongylus sp., Physaloptera sp., Diphyllobothrium sp. heterophyid, echinostome and dicrocoelid-like termatodes, Endolimax nana and Chilomastix mesnili were detected infrequently. Malaria parasitemias due to Plasmodium falciparum, P. vivax and P. malariae were detected in 4% of the sampled populations, Malayan filariasis was diagnosed in 21% of the subjects examined.
