We surveyed intestinal parasitic infections in hill-tribe schoolchildren residing permanently in Chiang Mai Province. The positive rate, of 403 stool specimens examined using the formalin-ether sedimentation technique, was 48.9%. No significant difference between male (50.8%) and female (47.1%) students was found for the infection. The most common protozoa was Entamoeba coli (40.9%), followed by Giardia lamblia (14.9%). The most common helminth was hookworm (13.4%), followed by Ascaris lumbricoides (8.0%), and Trichuris trichiura (6.9%). Opisthorchis viverrini, the most important liver fluke infection in northern Thailand, was found in only 1.5%. Children harbored 1-5 species of parasites, with the most being single infections (67.5%), followed by double infections (26.9%). This finding promoted an urgent need for the treatment of infected schoolchildren, and the prevention of re-infection must be underlined.
我们对长期居住在清迈府的山地部落学童的肠道寄生虫感染情况进行了调查。使用福尔马林-乙醚沉淀技术检查的403份粪便标本的阳性率为48.9%。在感染方面,未发现男学生(50.8%)和女学生(47.1%)之间存在显著差异。最常见的原生动物是结肠内阿米巴(40.9%),其次是蓝氏贾第鞭毛虫(14.9%)。最常见的蠕虫是钩虫(13.4%),其次是蛔虫(8.0%)和鞭虫(6.9%)。泰国北部最重要的肝吸虫感染——华支睾吸虫,仅在1.5%的儿童中发现。儿童体内寄生着1至5种寄生虫,其中单一感染最为常见(67.5%),其次是双重感染(26.9%)。这一发现促使迫切需要对受感染的学童进行治疗,并且必须强调预防再次感染。
