摘要：Introduction and objective. The contamination, seasonal and vertical distributions of Toxocara eggs in children’s recreationareas were estimated with respect to their accessibility to domestic and stray animals.Materials and methods. During autumn 2011 and spring 2012, a total 88 composite samples of soil/sand (300g each)were taken twice, from 2 depths, from 11 sandpits and 11 play areas situated in the city of Łódź, Poland. From the collectedmaterial, 528 samples (20g) were tested using the flotation method. Half the sample sites were secured from access to dogsand cats, while the other half were not.Results. The difference in the numbers of positive samples from sandpits and playing areas was significant (c2 = 13.72,p = 0.0002). The highest rate of contamination was observed in poorly-secured play areas (15.8% of positive samples and1.2 eggs/100 g of soil/sand). The average density of Toxocara eggs in secured play areas was 6 times less than that foundin unsecured areas, while secured sandpits were 3 times less contaminated than those unsecured. The contamination ratewas similar in autumn 2011 and spring 2012 (6.4% and 6.8%, respectively). An inverse relationship between the sand/soildepth and number of recovered Toxocara eggs was observed. Additionally, other intestinal helminth eggs (Ancylostomidae,Ascaris spp., and Trichuris spp.) and oocysts of Isospora spp. were also detected from soil samples collected from playingfields.Conclusions. The number of Toxocara eggs recovered decreased following fence construction around the examinedchildren’s play areas, but it did not sufficiently prevent the contamination by eggs. These data indicate the necessity foreducational programmes which should be implemented for the protection of the local child population from zoonoticinfection.
