ABSTRACT
In order to stablish the current prevalence by eggs of Toxocara canis, 110 squares of five zones of the Metropolitan Region of Santiago city were examined by a flotation in saturated zinc solution modified method. Samples were taken from different kinds of soil in the four seasons of the year and they were preserved under anaerobic conditions over 2 years. 18,2 percent of samples resulted positive to Toxara canis eggs and 24,4 percent were positive to nematodes larvae. No viable eggs were found. Western zone is the most contaminated of the city and autumn is the season in which we obtained higher recovery of eggs. Silty clay sample soil seems to be better than sandy soils on maintenance of studied eggs
