RESUMO
Soil-transmitted helminths (STHs) remain a major threat to the human health throughout the world, mostly in developing nations. Soil is usually contaminated by different parasitic stages through promiscuous defecation of man particularly children. This is more liable to occur in fields, public gardens and sides of streets or canals. Also, feces of domestic and wild animals & birds play a role in soil contamination. This study was conducted at Mansoura city and Batra village & El-Minia city and Zohra village representing the urban and rural areas of Dakahlia Governorate, Lower Egypt and Minia Governorate, Upper Egypt respectively. The most common helminthic stage presents in the soil of the two Governorates was Toxocara eggs. No ova was detected in-door yards in the urban areas, but only in the sides of streets, crop fields and fruit gardens, around houses and canal banks of both Governorates, and the highest intensity was 13-19 eggs/10 gm soil at canal banks at Zohra village, El-Minia Governorate, Upper Egypt.
