ABSTRACT
An analysis of canine faecal material collected in 13 different neighborhoods of the city of San Cristobal de Las Casas, Chiapas,
Mexico, was carried out in order to know the frequency of contamination caused by
Toxocara canis and other canine parasites. A
total of 200 samples from streets, a traffi c refuge and a park of the chosen neighborhoods in the city, were examined using the
zinc sulphate method. Evidence of parasites was found in 37% (n = 74) of the samples. The frequency of
T. canis eggs was found to
be 19 %, and that of
Ancylostoma caninum eggs 18.5%; the oocistes of Isospora canis represented 2.5%. These results indicate that
contamination of the soil of San Cristobal de Las Casas with these parasites, presents both a latent health risk for the population
and visitors of this city, besides the poor image fecal contamination gives to national and foreign tourists.
