Resumo: | The visceral larva migrans (VLM) is a syndrome observed in human infection with helminth larval eggs such as the Toxocara spp. that usually infects dogs and cats. Among the risk factors involved in the occurrence of VLM, particularly important is the size of these animal populations. Sorocaba is a city with a dog population twice as large as that recommended by the World Health Organization. This fact has led to a survey of the presence of Toxocara spp. eggs in public square soils of this city. Thirty squares were selected, fifteen located in the outskirts of the city and fifteen downtown. Soil samples were collected from five distinct sites in the same area. The material was homogenized and drained and 100 g was mixed with a saturated solution of magnesium sulfate and 5% potassium iodine. The floating material was analyzed under the light microscope. Toxocara spp. eggs were found in 16 squares, nine of which were located in the outskirts of the city and seven downtown. It was concluded that Sorocaba squares present a high rate of contamination with Toxocara spp. eggs. The squares in the outskirts of the city presented a higher occurrence of these eggs in comparison with those downtown, although the difference was not statistically significant (p >; 0.05). |

The squares in the outskirts of the city presented a higher occurrence of these eggs in comparison with those downtown, although the difference was not statistically significant (p >; 0.05). A larva migrans visceral - LMV - é uma síndrome causada pela infecção humana por ovos larvados de helmintos como o Toxocara spp., que usualmente compromete o cão e o gato. Dentre os fatores de risco para a ocorrência da LMV, destaca-se o tamanho da população desses animais. Sorocaba é uma cidade com uma população canina duas vezes superior à recomendada pela Organização Mundial de Saúde. Este fato levou à pesquisa da presença de ovos de Toxocara spp. no solo de áreas públicas nessa cidade. Foram escolhidas 30 praças, sendo 15 de regiões periféricas e 15 centrais. Coletaram-se amostras de solo de 5 locais distintos da mesma área. O material foi homogeneizado, tamisado e, em seguida, 100g foram misturados com uma solução saturada de MgSO4 com KI a 5%. O material flutuante foi analisado ao microscópio óptico comum. Encontraram-se ovos de Toxocara spp. em 16 praças, sendo 9 periféricas e 7 centrais. Conclui-se que a cidade de Sorocaba apresenta elevado índice de contaminação de suas praças por ovos de Toxocara spp. A periferia apresenta maior ocorrência desses ovos em relação às praças centrais, porém não-significante (p >; 0,05).
