Strongyloidiasis is endemic in many tropical and subtropical countries and reports from northeast India are very few.
A community-based study was carried out in Assam, India, to find out the occurrence of Strongyloides stercoralis.
Stool samples were obtained from 198 randomly selected individuals from the community. Samples were processed using direct microscopy with formal-ether concentration methods.
Seventeen numbers of samples showed the presence of Strongyloides stercoralis (8.5%). A total of 105 (53%) individuals were positive for at least one intestinal parasite. The other intestinal parasites detected were Ascaris lumbricoides (33.3%), Trichuris trichiura (9.1%), hookworm (7.1%), Enterobius vermicularis (1.5%), and Giardia cyst (1.5%). Five out of 17 individuals positive for S.stercoralis had associated gastrointestinal, respiratory, and/or cutaneous symptoms.The present study although not exhaustive for true prevalence calls for attention in the backdrop of high malnutrition and pulmonary tuberculosis.
类圆线虫病在许多热带和亚热带国家呈地方性流行，而印度东北部的相关报道却非常少。
在印度阿萨姆邦开展一项基于社区的研究，以查明粪类圆线虫的感染情况。
从该社区随机选取198人获取粪便样本。样本采用直接显微镜检查和甲醛 - 乙醚浓缩法进行处理。
17份样本显示存在粪类圆线虫（8.5%）。共有105人（53%）至少感染一种肠道寄生虫呈阳性。检测到的其他肠道寄生虫有蛔虫（33.3%）、鞭虫（9.1%）、钩虫（7.1%）、蛲虫（1.5%）和贾第虫包囊（1.5%）。17例粪类圆线虫阳性患者中有5例伴有胃肠道、呼吸道和/或皮肤症状。本研究虽然未能详尽得出真实患病率，但在营养不良和肺结核高发的背景下值得关注。
