The study determined the relation between prevalence of intestinal parasites and soil-transmitted parasites among households in Shiblanga representing a rural area of Qualyobia Governorate and Benha City representing an urban area of the same Governorate. The effect of soil's type on the intensity of parasites and to provide guidance on the prevention and control of soil transmitted parasitic infections for future studies in this field. This study was conducted at Benha City and Shiblanga village representing the urban and rural areas of Qualyobia Governorate. Geoparasites were investigated in-doors, around houses, in the fields and the streets from both areas. One hundred soil samples from Benha city and one hundred soil samples from Shiblanga village were collected .each hundred soil samples was collected in the form of: 25 samples from the fields, 25 samples in-indoor yards, 25 samples the streets,25 samples around houses. Approximately 200g soil was collected in plastic bags at 2-10cm depth from different parts. Stool samples from households in same areas were collected after taken oral consent. All soil samples were screened for parasites using different parasitological methods (Zinc sulphate flotation, ether sédimentation technique, modified Baerman’s apparatus and modified Berlese technique). All stool samples were examined using direct smear, formalin–ether concentration techniques for detection of helminthes eggs, and modified acidfast staining for detection of protozoa. The results showed that86/200soil samples were contaminated with different parasites, the prevalence rate of 43%. Soil samples from Shiblanga village showed
higher level of parasitic contamination (56%) and Benha city showed a lower level of contamination by different parasites (30%). Soil samples obtained from Manshiet El-Nour district, Benha revealed the highest level of parasitic contamination.
While, in Shiblanga, El-Mansheya district revealed the highest level of parasitic contamination. Clay soil was the most type of soil contaminated by helminthes. The10 houses out of 50 houses had the same parasites in the soil and in stool of their households, 8 houses in Shiblinga village and 2 houses in Benha city.
