Contamination of Sandpits with Soil-Transmitted Helminths Eggs in an Urban Environment

The aim of this study was to monitor the occurrence of the propagative stages of intestinal endoparasites in dog excrements collected within the close proximity of sandpits in an urban environment (Košice, Slovakia) and to determine the level of sandpits contamination with soil-transmitted helminths (STHs). A total of 201 dog faecal samples were examined for the presence of helminth eggs with 10.95 % of the samples being positive. In faeces the most prevalent eggs were those of Toxocara canis (7.46 %). The contamination of sand with STH eggs in 84 sandpits was also investigated. Toxocara spp. eggs were found in 21.43 % of the sandpits. The eggs from the family Ancylostomatidae and Toxascaris leonina were also present. Taenia type eggs and Trichuris sp. eggs occurred less frequently. In some samples, not only monoinfection but also co-infection with eggs of 2‒3 helminth species were detected. In conclusion, the environmental contamination of sandpits with STHs eggs might pose a significant threat to the public health.
