Abstract:
Toxocariasis is a zoonotic disease which caused by larvae of Toxocara cati and Toxocara canis. Human can be infected by ingestion of eggs of theses parasites and caused to Visceral Larval Migrant Syndrome (VLMS). One of the commons ways of human infection with theses eggs is the contamination of soil of public parks in cities. In the present study, 540 soil samples were taken from 60 public parks in Tabriz (northwest of Iran). Two hundred seventy samples were taken from 30 parks during warm seasons and 270 samples were taken from 30 parks during cold seasons of a year. Samples were tested by Clayton –lane method. From a total of 60 examined parks, 46 parks (76.66{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}) were contaminated with Toxocara spp. eggs and from 540 soil samples, 186 (34.44{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}) cases were contaminated with Toxocara spp. eggs. The level of contamination during cold seasons were significantly more than warm seasons (P<0.01) and the level of contamination around the trashes were more than other areas in the parks, but it was not significant. As the contamination of Tabriz public parks soil with Toxocara spp. eggs is relatively high, the people and specially children might get the contamination during stay in the parks and measures should be taken to control the stray cats and dogs and prevention of contamination of public areas by larva migrans agents is indicated.
