Description
Summary:Background: Soil contamination with parasites poses a significant and concerning risk for the transmission of parasitic infections to humans and animals. Considering the crucial role of soil as a potential source of parasite transmission, this study aimed to investigate the presence of helminth and protozoan parasites in the soil of public parks in Gorgan City. Methods: In this study, a total of 80 soil samples were collected from 16 public parks in Gorgan City in 2022. The soil samples were collected from various areas within the parks, including flower-making, children's play areas, walking paths, sitting areas, and garbage dumps. To isolate the parasites from the soil samples, a saturated solution of sodium nitrate was utilized. The samples were carefully examined under a microscope, and all isolates were stained and subjected to further investigation using special acid-fast stain. Results: Toxocara eggs were the most commonly detected parasite, present in 40% of the samples (n=32). Coccidia oocysts were found in 12.5% of the samples (n=10), which could potentially be Sarcocystis or Toxoplasma oocysts. Mites were also detected in 12.5% of the samples (n=10). Additionally, Cryptosporidium oocysts were identified using Ziehl-Neelsen's modified staining method, and they were found in 10% of the samples (n=8). Conclusion: Health education plays a vital role in raising awareness about preventive measures. Collecting reservoirs of parasites (Such as dogs and cats) and planning for the proper disposal of human waste also play an important role in prevention of this disease.
