A parasitology survey was conducted in five villages in North Sumatra, Indonesia. A total of 3,207 blood smears, 2,066 stool specimens and 969 sera were examined. Sixty (1.9%) inhabitants had malaria (Plasmodium vivax 41, P. falciparum 19), and 20 had Brugia malayi microfilaraemia. The most common intestinal helminths were Trichuris trichiura (87%), Ascaris lumbricoides (75%) and hookworm (58%). Other helminths found in low numbers were Enterobius vermicularis, Strongyloides stercoralis, Taenia sp., Fasciolid, Dicrocoeliid and Echinostoma sp. eggs. Entamoeba coli (25%) was the most common intestinal protozoa followed by Endolimax nana (8%), Entamoeba histolytica (7%), Giardia lamblia (6%), Iodamoeba bütschlii (5%), Entamoeba hartmanni (1%) and Chilomastix mesnili (1%). The amoeba prevalence rate was 31 per cent. Testing of sera for Entamoeba histolytica and Toxoplasma gondii antibodies by the indirect haemagglutination test demonstrated positive reactors in 13 per cent and nine per cent of the population respectively. The greatest number of seropositives for Toxoplasma gondii was at elevations of sea level to five meters and the lowest number at elevations of 5OO-1,000 meters.
在印度尼西亚北苏门答腊的五个村庄开展了一项寄生虫学调查。共检查了3207份血涂片、2066份粪便标本和969份血清。60名（1.9%）居民患有疟疾（间日疟原虫41例，恶性疟原虫19例），20名居民有马来布鲁线虫微丝蚴血症。最常见的肠道蠕虫为鞭虫（87%）、蛔虫（75%）和钩虫（58%）。发现数量较少的其他蠕虫有蛲虫、粪类圆线虫、带绦虫属、片形吸虫、双腔吸虫和棘口吸虫属虫卵。结肠内阿米巴（25%）是最常见的肠道原虫，其次是微小内蜒阿米巴（8%）、溶组织内阿米巴（7%）、蓝氏贾第鞭毛虫（6%）、布氏嗜碘阿米巴（5%）、哈氏内阿米巴（1%）和梅氏唇鞭毛虫（1%）。阿米巴患病率为31%。通过间接血凝试验检测血清中的溶组织内阿米巴和弓形虫抗体，结果显示分别有13%和9%的人群呈阳性反应。弓形虫血清阳性率最高的是海拔海平面至5米的地区，最低的是海拔500 - 1000米的地区。
