Human parasitoses of the Malili area, South Sulawesi (Celebes) province, Indonesia.

A biomedical survey was conducted in 9 villages in the Malili area of South Sulawesi, Indonesia. Blood specimens were examined for malaria and microfilariae; stool specimens were examined for intestinal parasites. Malaria parasitemias were rare; Plasmodium falciparum was detected in 10 and P. vivax in 11 of 985 blood smears. Malayan filariasis was endemic to all villages surveyed. The overall prevalence of detectable microfilaremias was 15%, varying from 34% in Kawata to 1% in Nuha. Microfilarial densities, expressed as MfD50 averaged 8.0 and varied from 1.1 in Timampu to 16.0 in Karabbe. Intestinal parasites were common. Although Schistosoma japonicum was not found, 97% of the examined had one or more intestinal parasites as follows: Ascaris lumbricoides (74%), Trichuris trichiura (65%), hookworm (62%), Entamoeba coli (38%), Endolimax nana (10%), Entamoeba histolytica (6%), Iodamoeba bütschlii (4%), Entamoeba hartmanni (3%), Giardia lamblia (2%) Chilomastix mesnili (1%) and Enterobius vermicularis (1%). Strongyloides stercoralis larvae and Hymenolepis nana eggs were detected once each and heterophyid-like eggs were detected twice.
