Toxocariasis is a parasitic zoonose caused by the infection of larval nematode Toxocara species. A total of 285 soil samples from January to March 2009 in 18 public parks were collected to test for soil contamination with Toxocara eggs. Soil samples were investigated for the present of Toxocara eggs using sucrose flotation method. Distribution of Toxocara spp. eggs in samples collected from public parks was 63.3%. The highest number of eggs recovered from 200 g of soil was 128. A total 304 eggs were recovered and 42.1% fully developed to embryonated egg stages. The contamination rate in second region in the studied areas was higher than the other regions. A similar tendency was observed in parks size, so that parks higher than 10,000 m2 were more highly contaminated. The present investigation clearly shows that public parks have been contaminated with Toxocara eggs in Khorram Abad, suggesting that care should be taken when using public parks.
弓首蛔虫病是一种由幼虫期线虫弓首蛔虫属感染引起的寄生性人畜共患病。2009年1月至3月期间，从18个城市公园采集了总共285份土壤样本，以检测土壤中是否存在弓首蛔虫卵污染。采用蔗糖漂浮法对土壤样本进行弓首蛔虫卵检测。从城市公园采集的样本中，弓首蛔虫属虫卵的分布率为63.3%。从200克土壤中回收的虫卵数量最多为128个。总共回收了304个虫卵，其中42.1%发育到了胚胎化卵阶段。研究区域中第二个区域的污染率高于其他区域。在公园面积方面也观察到了类似的趋势，即面积超过10000平方米的公园污染程度更高。本次调查清楚地表明，霍拉马巴德的城市公园已被弓首蛔虫卵污染，这表明在使用城市公园时应予以注意。
