Determinación de parásitos intestinales humanos en vehículos hídricos, San Andrés. Chimborazo, 2019

Water, an important resource for the world, today has become the vehicle for the transmission of intestinal parasites to humans due to anthropogenic causes. The objective of this research was to determine human intestinal parasites in water sources of the rural parish San Andrés, Chimborazo province-Ecuador. A cross-sectional field investigation was conducted, with an intentional non-probabilistic sampling, in which a total of 214 water samples were collected, in irrigation canals that supply the area's crops, piped water and stagnant water from the field. A community for the identification of parasites, the modified Bailenger technique was performed using conventional microscopy as an instrument, and for the identification of coccidia, modified Ziehl-Neelsen staining was performed. The results show that the three types of water have contamination with chromists, protozoa and helminths. Pathogenic and non-pathogenic parasites identified in the three types of water, 39.82% of pathogenic parasites were found in irrigated water, with Cryptosporidium sp and nematode larvae (45.95%) being the most prevalent protozoan, piped water Cryptosporidium sp (17.01%) and in water stagnant to Eimeria (36.67%). Finally, a formula was proposed which allowed obtaining a predisposition factor for parasitosis that resulted in 0.26 which indicates the possibility of transmission of parasites using local water, which represents a risk for its inhabitant important agricultural area of the country.
