Resumen
En el presente trabajo se estudió la contaminación del suelo con especies parasitarias en el ambiente domiciliario de un barrio periurbano del Nordeste Argentino y se asoció con variables sanitarias. Las muestras de suelo fueron analizadas utilizando tres técnicas diferentes: sedimentación por centrifugación; flotación de Willis Molloy y con solución de Sheather. De las 30 casas analizadas, 12 (40,0%) presentaron al menos una forma parasitaria en las muestras de suelo. Registramos tres taxones, entre ellos, las larvas de nematodes (relacionadas a ancilostomídeos) fueron los de mayor prevalencia, reportadas en el 30% de las viviendas, seguido por huevos de Toxocara canis y Trichuris vulpis y ooquistes de Cytoisospora canis en el 3,3% de las casas. No se observó asociación estadística entre contaminación del suelo y las variables sanitarias (p > 0.05). Estos resultados preliminares demuestran que el suelo del ambiente doméstico podría representar un alto potencial de infección y re-infección para humanos, principalmente niños y sus mascotas.
In this research, soil contamination in household environment with soil-borne parasites species in dwellings of a periurban neighborhood and a shantytown in northeast of Argentina was described and associated with sanitary variables. Each house evaluated was considered as a unit of analysis. The samples were analyzed under three different techniques: centrifugal sedimentation; Willis Molloy flotation and flotation with Sheather's solution. Out of the 30 houses analyzed, 12 (40.0%) presented at least one parasitic forms in soil samples. We recorded three taxa, the most prevalent were nematodes larvae (related to hookworms), reported in the 30% of dwellings followed by Toxocara canis and Trichuris vulpis eggs and Cytoisospora canis oocyst in the 3,3% of houses. No statistical association was observed between soil contamination and the sanitary variables (p > 0.05). These preliminary results demonstrate that domestic environment soil could represent a high potential for infection and re-infection for humans, principally young children and their pets.
