Abstract
Abstract Background and objectives: Water-born diseases are typically caused by pathogens transmitted by orofecal way. Because it is no practical and no economical and also it is time-consuming to find water-born pathogens in water reservoirs, the laboratory studies are performed on the basis of indicator microorganism. Escherichia coli is considered as the most important indicator bacterium for water monitoring. The aim of this study was to evaluate the three methods of Pour Plate (PP), Most Probable Number (MPN) and Membrane Filter (MF) in isolation of Escherichia coli in well water of Parks. Material and Methods: One hundred and sixty five samples of well water, from five geographical zones of north, south, east, west and center of Tehran, were taken in a sterile condition and sent to microbiology department of health faculty to assess with three methods of PP, MPN and MF. The results were analyzed by chi-square. Results: The results indicate that 90 water samples (54.5%) aren’t health. The samples taken from south of Tehran are most contaminant than other zones. The highest contaminated Samples (54.5%) are related to membrane filtration method in comparison with MPN (34.5%) and PP (27.3%). Conclusion: Since the MF method can recognize the contaminants quickly and effectively, we recommend it more. Based on these results, it is essential to educate children not to drink well water in parks. Keywords: well water contamination, Escherichia coli, Tehran's parks

Abstract
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.
