Abstract
Bu çalışmada Ağrı il merkezinde bulunan 18 çocuk parkının askarit yumurtaları ile kontaminasyonunun belirlenmesi amaçlanmıştır. Bu amaçla Mart-Mayıs 2023 tarihleri arasında her bir parktan tekniğine uygun bir şekilde toplanan 16 dışkı, 28 toprak ve 42 kum örneği laboratuvarda helmint yumurtaları yönünden mikroskobik olarak incelenmiştir. Dışkı örneklerinin 6’sının Toxocara sp., 3’ünün ise Ancylostoma caninum yumurtaları ile kontamine olduğu bulunmuştur. Toprak örneklerinin 5’inde Toxocara sp. ve 2’sinde Diphyllidium caninum yumurtaları tespit edilmiştir. Kum örneklerinin 5’inde Toxocara sp. ve 1’inde Diphyllidium caninum yumurtaları belirlenmiştir. Bu çalışma neticesinde Ağrı ilindeki çocuk parklarının zoonotik kedi-köpek askaritleri ile kontamine olduğu görülmüştür.

Abstract
In this study, it was aimed to determine the contamination of 18 parks with ascarid eggs in Ağrı. For this aim, in accordance with the technique 16 stool, 28 soil, and 42 sand samples were collected from each park between March-May 2023 and examined microscopically for the presence of helminth eggs in the laboratory. While 6 stool samples were found to be contaminated with Toxocara sp., Ancylostoma caninum eggs were found in 3 stool samples. Toxocara sp. eggs were seen in 5 and Diphyllidium caninum eggs were seen in 2 soil samples. In 5 Toxocara sp. and 1 Diphyllidium caninum eggs were determined in sand samples. As a result of this study, it was seen that the playgrounds in the Ağrı region were contaminated with zoonotic cat-dog ascarid species.
