Keeping in view of heavy burden of intestinal parasitosis, present study was done to find out the prevalence of intestinal parasitic infection in children (aged <16 years) of Sukumbasi (people living without land ownership) Basti (community) in Kathmandu Valley. A total of 279 stool samples collected in clean, dry and screw capped plastic container were firstly examined for the presence of adult worm and/or segments of worms. Samples fixed in 10% formal-saline were then examined microscopically after concentration by formal-ether sedimentation technique. Overall parasite positive rate was 43.3% (121/279) with no significant difference in two genders (Boys: 48.3%, 73/151; Girls: 37.5%, 48/128) (p=0.07). Altogether 11 species of parasites were detected. Of them Giardia lamblia was most common followed by Entamoeba histolytica, Trichuris trichiura and others. Positive rate was higher in Tibeto-Burman (55.0%, 77/140) and the least in Indo-Aryan (25.4%, 27/ 106) (p=0.01) ethnic groups. Children taking anti-parasitic drug in last six months had significantly low positive rate (25.4%, 15/59) than others (48.2%, 106/220) (p=0.002). Results of this study suggestive of periodic administration of anti-parastic drugs and need for improvement of sanitary/hygienic practice.
鉴于肠道寄生虫病的沉重负担，开展了本研究以查明加德满都谷地苏昆巴希（无土地所有权者）巴斯蒂（社区）16岁以下儿童肠道寄生虫感染的患病率。总共279份采集于干净、干燥且带螺旋盖塑料容器中的粪便样本，首先检查是否存在成虫和/或虫体节段。然后，对用10%甲醛生理盐水固定的样本采用甲醛-乙醚沉淀技术浓缩后进行显微镜检查。总体寄生虫阳性率为43.3%（121/279），两性之间无显著差异（男孩：48.3%，73/151；女孩：37.5%，48/128）（p = 0.07）。总共检测到11种寄生虫。其中，蓝氏贾第鞭毛虫最为常见，其次是溶组织内阿米巴、毛首鞭形线虫等。藏缅族的阳性率较高（55.0%，77/140），印欧语族的阳性率最低（25.4%，27/106）（p = 0.01）。在过去六个月内服用过抗寄生虫药物的儿童阳性率（25.4%，15/59）显著低于其他儿童（48.2%，106/220）（p = 0.002）。本研究结果表明需定期服用抗寄生虫药物，并需要改善卫生/卫生习惯。
