The frequency of Toxocara spp eggs in public parks was determined from March 1995 to February 1996. One hundred and twelve samples were collected from 10 public parks in Botucatu, São Paulo State, Brazil. Samples were processed by the decinormal sodium hydroxide concentration method. Out of the 120 soil samples analyzed, 21 were contaminated with Toxocara spp eggs, corresponding to a 17.5% rate of infestation. Of the ten squares submitted to analysis during the year, six presented contamination. Most of the ova found presented characteristics of inviability, with a consequent low chance of human infection, although the population is not free from the risk of contracting this zoonosis.
1995年3月至1996年2月期间，对公园中弓蛔虫属虫卵的出现频率进行了测定。从巴西圣保罗州博图卡图的10个公园采集了112份样本。样本采用十分之一当量氢氧化钠浓缩法进行处理。在分析的120份土壤样本中，有21份被弓蛔虫属虫卵污染，感染率为17.5%。在当年接受分析的10个区域中，有6个区域存在污染情况。尽管人群感染这种人畜共患病的风险依然存在，但发现的大多数虫卵都呈现出无法存活的特征，因此人类感染的可能性较低。
