Background: Eggs of Ancylostoma spp. disseminated for defecate of dogs and cats in public
areas, are extremely resistant to adverse environmental conditions, capable of surviving in soil for
many months; this represent risk for health humans and pets that have contacted with
contaminated sand of beaches can act as reservoir or vector of this zoonotic parasite, that
potentially can infect the host by eggs and larvae penetrating the skin of bare feet or hands and
produce Larva migrans, also known as creeping eruption or sandworm eruption, characterized by
tortuous migratory lesions of the skin. The objective of this work was to determine the presence of
Ancylostoma spp. in moist sand of beaches of Navolato, Sinaloa, Mèxico.
Methods: The composite samples of sand of seven beaches were determined for representative
samples described by the technique of Thrusfield (2005) was used: n=[t*SD/L]2. Where
n=sample size, t=value of the normal distribution (Student t) for a 95% confidence level (t =1.96),
L=accepted error or precision (5%), and SD=weighted disease prevalence (%); the total of
composite sample of sand determined by random samplings was 254, took surface moist sand
scraping of 100 grams of sand for each sample and deposited it in plastic bags; transferred to the
laboratory of parasitology of the FMVZ-UAS to be analyzed by the sedimentation technique.
Results: Of the 254 composite samples of sand of the seven beaches, 96 (37.7 %), were
positive to Ancylostoma spp.
Conclusion: The contamination with Ancylostoma spp. represent high risk for the pets and public
health, yet residents as visitors ignore about parasitic diseases that dogs can transmit them it is
necessary implement control strategies and education for the prevention of the infections.
