The frequency of parasitic contamination of public areas in the municipality of Pelotas, state of Rio Grande do Sul, Brazil, was studied between June 2010 and May 2011, when soil samples were collected from eight city squares. Out of 400 samples submitted to centrifugal floatation technique in solution of sodium dichromate with density of 1.35, 176 (44%) proved positive for at least one parasite; 29 (16.5%) samples were multi-infested. The results showed that there was a significant soil contamination rate in all the parks included in the study. The positivity rate was higher for hookworms eggs (13.5%) and Toxocara eggs (8.8%); Trichuris, Ascaris and Capillaria eggs were also detected. This study shows the risks to which the population is exposed in relation to zoonotic geohelminths, and suggests that sanitation and health education measures should be implemented in the municipality.
2010年6月至2011年5月期间，对巴西南里奥格兰德州佩洛塔斯市公共场所的寄生虫污染频率进行了研究，当时从八个城市广场采集了土壤样本。在400份用密度为1.35的重铬酸钠溶液进行离心浮选技术检测的样本中，176份（44%）至少对一种寄生虫检测呈阳性；29份（16.5%）样本受到多种寄生虫感染。结果表明，该研究涵盖的所有公园土壤污染率都很高。钩虫卵（13.5%）和弓首蛔虫卵（8.8%）的阳性率更高；还检测到鞭虫卵、蛔虫卵和毛细线虫卵。这项研究显示了人群面临的与动物源土源性蠕虫有关的风险，并建议该市应实施卫生和健康教育措施。
