Toxocara spp. and others helminthes in soil samples from squares and parks in Puerto Ordaz, Caroní municipality, Bolívar state, Venezuela

Abstract

The squares and parks are recreation areas, especially for children; but the presence of eggs of Toxocara spp. and other helminths in these places can represent a risk of contracting toxocariasis and other helminthiasis of zoonotic origin. A study was carried out to determine the presence of Toxocara spp. eggs and other helminths in squares and parks from Puerto Ordaz, Caroní municipality, Bolívar state, Venezuela. Each square was divided into 4 quadrants and from each one a soil sample was collected which was processed using the techniques of Willis-Malloy, Lutz and Araraki. Of the 10 squares studied, 8 (80%) identified helminth eggs or larvae; there were positive places in the three parishes. Of the total of 40 processed soil samples, 15 (37.5%) were positive for the presence of larvae or helminth eggs, being the frequency of Toxocara spp., of 32.5% (13/40). In addition to the presence of Toxocara spp. (32.5%), highlighted the finding of Strongyloides spp. (5.0%), Ascaris spp. (2.5%) and Ancylostomideos (2.5%). In conclusion, an 80% frequency of contamination with eggs and larvae helminth was determined in the squares/parks evaluated, highlighting Toxocara spp. in 32.5% of the samples studied
