Giardia intestinalis is an intestinal parasite widely prevalent in children attending daycare centres worldwide and has been associated with undernutrition. Stool samples from 48 Guatemalan children (aged 1.5-7 years) attending participating daycare centres were analyzed over five weeks for presence of Giardia intestinalis using light microscopy, ELISA, and rapid dipstick test. Giardia prevalence rates were 43.7% at Week 0 and 44.7% at Week 4, based on ELISA. Intensity, but not prevalence, of infection showed a trend toward decreased weight-for-age (1-tailed p = 0.08). We believe that ELISA analysis of stool samples may be further adapted for measuring the intensity of infection in humans.
肠贾第虫是一种肠道寄生虫，在世界各地日托中心的儿童中广泛流行，并且与营养不良有关。在五周的时间里，对来自危地马拉参与调查的日托中心的48名儿童（年龄在1.5至7岁之间）的粪便样本进行分析，采用光学显微镜、酶联免疫吸附测定（ELISA）和快速试纸检测法检测是否存在肠贾第虫。基于ELISA检测，第0周的贾第虫感染率为43.7%，第4周为44.7%。感染强度而非感染率显示出年龄别体重下降的趋势（单尾p = 0.08）。我们认为，粪便样本的ELISA分析可能会进一步改进，以用于测量人类的感染强度。
