Abstract
Sandpits in recreational areas may represent an important environment for transmission of several parasite zoonosis, among them the Cutaneous Larva Migrans (CLM), caused by the penetration of Ancylostoma sp. larvae from dogs and cats through human skin. Contamination of sandpits by Ancylostoma sp. eggs or larvae was investigated in children recreational areas from 11 public squares of Ribeirão Preto. From May to December, 2003, five sand samples were collected from each recreational area. Larvae recovery was performed by means of Baermann's method, while egg detection was done by centrifugal-flotation technique in saturated solutions of magnesium sulphate with 5% potassium iodide (d = 1,33 g/cm3 ), and zinc sulphate (d = 1,20 g/cm3 ), after washing out with Tween 80. The presence of larvae was observed in six (54%) recreational areas. In four (36%) of them Ancylosotoma sp. eggs were found. These results indicate a risk of acquiring CLM by the users of those areas.References
