To clarify the efficacy of repeated stool examinations by the agar plate culture method for the detection of Strongyloides stercoralis infection, 4,071 stool samples collected from 2,406 patients > 50 years of age in Ryukyu University Hospital were examined. The cumulative detection rate of S. stercoralis infection was 4.7% (112/2,406). At the first, second, third, and beyond fourth examinations, the detection rates were 3.6% (86/2,406), 1.5% (12/786), 2.6% (10/392), and 2.0% (4/198), respectively. From these results, the cumulative detection rate was estimated to be 7.4% when three stool samples were examined for all patients. Our study showed that repeated stool examinations increase the sensitivity of detection of S. stercoralis infection.
为明确采用琼脂平板培养法反复进行粪便检查对检测粪类圆线虫感染的效果，我们对琉球大学医院收集的2406例50岁以上患者的4071份粪便样本进行了检查。粪类圆线虫感染的累积检出率为4.7%（112/2406）。第一次、第二次、第三次及第四次以上检查时的检出率分别为3.6%（86/2406）、1.5%（12/786）、2.6%（10/392）和2.0%（4/198）。根据这些结果，估计对所有患者检查三份粪便样本时，累积检出率为7.4%。我们的研究表明，反复进行粪便检查可提高粪类圆线虫感染检测的敏感性。
