The aim of this study was to estimate the presence of Echinococcus multilocularis DNA in the soil in rural areas of Varmia-Masuria Province, Poland, which is the region with the highest recorded number of human alveolar echinococcosis (AE) cases in this country. In total, 62 soil samples were analyzed. Samples were collected in forests near the lairs of foxes, as well as from arable fields, kitchen gardens and farmyards. The parasite DNA was detected in 11.3% of the samples. This study is the first environmental survey of the presence of E. multilocularis DNA in soil. The results demonstrate that the soil can be a direct source of human infections. These results should motivate the appropriate institutions to introduce informative and educational campaigns about the risk of infection, as well as developing methods for protecting the population, especially those living in at-risk areas.
本研究旨在评估波兰瓦尔米亚-马祖里省农村地区土壤中细粒棘球绦虫（Echinococcus multilocularis）DNA 的存在情况，该省是该国记录到的人类泡型包虫病（alveolar echinococcosis，AE）病例数量最多的地区。共分析了 62 个土壤样本。样本采集自狐狸巢穴附近的森林，以及耕地、菜园和农场。在 11.3%的样本中检测到寄生虫 DNA。本研究是对土壤中细粒棘球绦虫 DNA 存在情况的首次环境调查。研究结果表明，土壤可能是人类感染的直接来源。这些结果应促使相关机构开展关于感染风险的宣传和教育活动，并开发保护民众的方法，尤其是居住在高危地区的民众。
