Parasitology survey and seroepidemiology of amoebiasis in South Kalimantan (Borneo), Indonesia.
A parasitology surevy was conducted among inhabitants of 7 villages in 3 regencies in South Kalimantan Province, Indonesia. A total of 2,169 stool specimens, 2,756 blood smears and 1,027 serum specimens were obtained, representing samples from approximately 10%, 12% and 5% of the population, respectively. One to 8 different intestinal parasitic infections were detected in 97% of the people. Those parasites most frequently found were Trichuris trichiura (83%), Ascaris lumbricoides (79%), and hookworm (65%), followed by Entamoeba coli (37%), Endolimaxnana (12%), Entamoeba histolytica (12%), Iodamoeba bütschlii (11%), Giardia lamblia (5%), Entamoeba hartmanni (2%), Chilomastix mesnili (2%). Other parasites found were Enterobius vermicularis, Strongyloides stercoralis, Capillaria sp., Echinostoma sp., Hymenolepis diminuta, and Trichomonas hominis. Giardia lamblia was found more often in younger people and Entamoeba coli, Iodamoeba bütschlii and hookworm in the older age group. Ascaris lumbricoides occurred more frequently in females, and hookworm in males. Plasmodium vivax and Plasmodium falciparum were found in the blood smears of 4.4% of the people, mostly in the younger age groups. Seroepidemiological studies on amoebiasis were done by use of the indirect hemagglutination test with antigens prepared from the HK9 strain of Entamoeba histolytica maintained in axenic cultures. The frequency distribution of the reciprocal antibody titers showed a bimodal distribution with 34% of the population demonstrating positive reactions at titers of 1:128 or greater.[1]References
