title: Intestinal parasitic infections in Bekasi district, West Java, Indonesia and a comparison of the infection rates determined by different techniques for fecal examination.
abstract: This study was undertaken to determine the current status of intestinal parasitic infections among schoolchildren in West Java, Indonesia, and to compare the infection rates obtained by three different methods of fecal examination. A total of 285 fecal samples were collected from 131 males and 154 females at a junior high school. Samples were brought to the Department of Parasitology, Faculty of Medicine, University of Indonesia, and were examined for parasites by the Kato-Katz thick smear method (K-K). The residual samples were suspended in more than five volumes of 2% potassium dichromate solution and brought to the Department of Parasitology, Kobe University School of Medicine, Japan, where they were examined for parasites by the Army Medical School method (AMS III) and by the Sucrose Centrifugal Flotation method (SFL). The K-K revealed a total of two helminths with a prevalence of 10% (29/285). In contrast, nine species of parasites, 31% (89/285) positive, were obtained by AMS III, while 10 species, 22% (62/285) were found by SFL. Overall, 12 species of parasites were detected by the three methods: four species of nematoda (Trichuris trichiura, Ascaris lumbricoides, hookworm, and Enterobius vermicularis); five species of protozoa (Giardia intestinalis, Entamoeba histolytica-like cyst, E. coli, Cyclospora sp, Blastocystis hominis); two unidentified species of nematode eggs; and one unidentified species of mite egg.
