ABSTRACT
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.

A biomedical survey was conducted in several areas of Irian Jaya, Indonesia in July 1972 in association with an investigation of reports of a cholera outbreak. Stool specimens, blood smears and sera were collected and examined for evidence of parasitic as well as other infectious diseases. A total of 114 stools were examined and the most commonly found intestinal parasites were Trichuris trichiura (94%), Ascaris lumbricoides (74%), hookworm (58%), Entamoeba coli (15%), Endolimax nana (8%), Entamoeba histolytica (7), Entamoeba hartmanni (4%), Giardia lamblia (3%) and Chilomastix mesnili (3%). A total of 513 blood smears were examined and Wucheria bancrofti microfilariae were detected in 4% and malaria in 4% (Plasmodium falciparum 3%, Plasmodium vivax 2%). The malaria and filarial positive individuals lived in Beeuw, Waigeo and Arar, Sorong. These parasitic infections were not detected in people from Biak City and Sburia, Biak. Sera were collected from 357 persons and significant antibody titers were found for Entamoeba histolytica (4%) Toxoplasma gondii (7%), Influenza A2 Hong Kong 68 (65%), Influenza B Taiwan 68 (78%), Japanese encephalitis virus (87%) and Dengue 1 virus (79%).

Antibodies against plague were lacking in 237 wild mammal sera from Java and 103 from Kalimantan. Wild mammal spleens, 114 from Java and 18 from Kalimantan were negative for plague bacilli. A variety of mammalian species and areas was examined.
