“…The invasion of the human body by nematode parasites of other animals is an atypical development of the parasitic species involved, which are unable to complete its life cycle. Under these conditions, it is observed that the infective larval form cannot progress to the adult worm, and its abnormal migration in the host stops in different tissues such as skin, eye, liver, lungs or other organs 12,17,18 . Nematodes that penetrate through the skin but still wander between the epidermis and dermis, resulting in clinical cutaneous larva migrans 12,18 , whereas nematodes that enter the body orally and should experience the typical pulmonary cycle after reaching the digestive tract are likely to finally reside in the liver or lungs or other organs, causing the clinical syndrome visceral larva migrans 17 .…”

SUMMARYThe contaminated soil with mammal feces is an important factor of risk to infection with zoonotic diseases. Amongst these zoonoses are visceral larva migrans and cutaneous larva migrans caused by Toxocara spp. and Ancylostoma spp., respectively. The aim of this study was to assess the environmental contamination by Toxocara spp. eggs and hookworms (Ancylostoma spp.) in public parks and squares in the city of Guarulhos, a metropolitan area of São Paulo, São Paulo State, Brazil. Soil samples were collected, between September and December 2010, and examined using the centrifugal flotation technique with sodium dichromate and zinc sulphate as well as the modified Baermann method. Notably, 35 (74.5%) of the 47 districts surveyed in Guarulhos possessed samples contaminated with Toxocara spp. and/or eggs or larvae of Ancylostoma spp. The frequency of Toxocara spp. and Ancylostoma spp. in the samples from public areas was 68.1% and 46.8%, respectively. Overall, the eastern side of Guarulhos is the region with the highest occurrence of causative agents of larva migrans. In all collection sites, the presence of feces from dogs and cats accompanied by their owners and stray animals were observed. Notably, it is important to adopt measures to control dog and cat breeding, to treat infected animals, and provide health education to the population.
