The aim of the studies was to compare the degree of soil contamination with Toxocara canis and T. cati eggs in rural and urban areas depending on time of sampling and type of places examined. Material and methods. Over 2000-2005 a total of 538 soil samples from 3 villages and 368 from Poznań city (Poland) areas were examined for Toxocara spp. eggs. In spring 418 samples in rural areas and 184 samples in urban areas were collected and in autumn 120 and 184 respectively. The samples were examined using flotation technique in saturated sodium nitrate. The discrimination of T. canis and T. cati eggs was based on the size of eggs and transparency of shell layers. Results. The contamination of soil with Toxocara eggs was higher in the urban areas (19.8% positive samples) than in the rural ones (15.6% positive samples) and city or village-backyards were most heavily contaminated. Both, in the villages and in the city, the degree of soil contamination with eggs in spring and autumn was similar (17.6 and 14.8% positive samples respectively). T. cati eggs were much more prevalent in urban areas (97% of all eggs recovered) while T. canis in rural areas (84% of all recovered eggs). The share of T. canis and T. cati eggs in soil contamination did not depend on the time of sampling.
这些研究的目的是根据采样时间和被检查地点的类型，比较农村和城市地区土壤被犬弓首蛔虫和猫弓首蛔虫卵污染的程度。材料与方法。在2000年至2005年期间，共对来自3个村庄的538份土壤样本和来自波兰波兹南市地区的368份土壤样本进行了弓首蛔虫属虫卵检测。春季，在农村地区采集了418份样本，在城市地区采集了184份样本；秋季则分别采集了120份和184份样本。采用饱和硝酸钠浮选技术对样本进行检测。犬弓首蛔虫卵和猫弓首蛔虫卵的鉴别基于虫卵大小和卵壳层透明度。结果。城市地区土壤被弓首蛔虫卵污染的程度（阳性样本占19.8%）高于农村地区（阳性样本占15.6%），城市或村庄的后院污染最为严重。在村庄和城市中，春季和秋季土壤被虫卵污染的程度相似（阳性样本分别占17.6%和14.8%）。猫弓首蛔虫卵在城市地区更为普遍（占所有检出虫卵的97%），而犬弓首蛔虫卵在农村地区更为普遍（占所有检出虫卵的84%）。犬弓首蛔虫卵和猫弓首蛔虫卵在土壤污染中所占比例与采样时间无关。
