Millions of people worldwide, and especially schoolchildren, may be infected by geohelminths due to their exposure to a contaminated environment. The aim of this study was to evaluate soil contamination by Ancylostoma spp. and Toxocara spp. eggs in recreation areas at elementary schools in Pelotas, state of Rio Grande do Sul, Brazil. Sand samples were collected from 22 schools and were processed using the centrifugal flotation method. Helminth eggs with zoonotic potential were found in 12 out of the 22 schools (54.5%). Contamination by Ancylostoma spp. and Toxocara spp. was observed in 36.4% (8/22) and 27.3% (6/22) of the soil samples collected at these schools, respectively. These findings of eggs show that the school communities are exposed to risks of zoonotic transmission.
全世界数百万人，尤其是学童，由于接触到被污染的环境，可能会感染土源性寄生虫。本研究旨在评估巴西南里奥格兰德州佩洛塔斯市小学娱乐区土壤中Ancylostoma spp. 和 Toxocara spp. 卵的污染情况。从 22 所学校采集了沙样，并使用离心浮选法进行处理。在 22 所学校中的 12 所（54.5%）发现了具有动物源性的寄生虫卵。在这些学校采集的土壤样本中，分别观察到 Ancylostoma spp. 和 Toxocara spp. 的污染率为 36.4%（8/22）和 27.3%（6/22）。这些卵的存在表明学校社区面临动物源性传播的风险。
