Rhabditiasis, caused by nematode, has long been recognized as a veterinary concern, however, human infection is exceedingly rare. For the first time in Bangladesh, this study confirmed human rhabditiasis infecting a 12-year-old child. The identification was made based on morphometric features and confirmed by amplifying the mitochondrial 1 gene. During microscopical examination of stool samples, heavy infection with several developmental stages (larvae, adult males, and females) of nematodes was observed. Following morphometric analysis, the nematode was identified as sp. The features used in confirming the species were elongated tail, bulbous enlargement of mid-esophagus, and presence of adult males passed in the stool. The results of the phylogenetic analysis showed that isolates of sp. belonged to distinct clades alongside .
由线虫引起的类圆线虫病长期以来一直被认为是兽医关注的问题，然而，人类感染极为罕见。在孟加拉国，本研究首次证实一名12岁儿童感染了人类类圆线虫病。该鉴定基于形态特征，并通过扩增线粒体1基因得到证实。在粪便样本的显微镜检查中，观察到线虫的几个发育阶段（幼虫、成年雄虫和雌虫）重度感染。经过形态分析，该线虫被鉴定为类圆线虫属。用于确认该物种的特征是尾巴细长、食管中部呈球根状膨大以及粪便中有成年雄虫排出。系统发育分析结果表明，类圆线虫属的分离株与其他线虫一起属于不同的进化枝。
