The objective of this study was to verify the presence of Toxocara spp eggs in the public squares ground in Uberlândia, region of Triângulo Mineiro, from October 1991 to January 1992. The city has 89 squares distributed in 39 boroughs. In order to have an outline of the parasite's occurrence, ground and sand (when existent) samples were collected from one square per boroughors. The squares were determined by draw. The homogenized ground samples of distinct points of the 39 squares, were collected in plastic flasks and analysed by the methods of fluctuation in sodium chloride saturated solution and magnesium sulphate saturated solution which contained 5% of potassium iodate. Both methods were executed twice for each sample. The results showed that the ground of 9 squares (23.07%) was contaminated, 6 of which were located near downtown. The execution of more than one laboratorial method permitted the agent's identification in a greater percentage of squares.
本研究的目的是验证1991年10月至1992年1月在米纳斯吉拉斯三角地区乌贝兰迪亚市的公共广场地面上是否存在弓蛔虫属虫卵。该市有89个广场分布在39个行政区。为了了解寄生虫的发生概况，从每个行政区的一个广场采集了地面和沙子（如有）样本。广场通过抽签确定。从39个广场的不同点采集的均质地面样本收集在塑料瓶中，并通过含有5%碘酸钾的氯化钠饱和溶液和硫酸镁饱和溶液波动法进行分析。每个样本的两种方法均执行两次。结果表明，9个广场（23.07%）的地面受到污染，其中6个位于市中心附近。采用多种实验室方法可在更高比例的广场中识别出病原体。
