“…Additionally, the canine population density varies from region to region, especially stray dogs. This one factor is related to socio-economic aspects of each population group in the same city 41,42 ; in this context, the peripheral areas of large cities offer better conditions for the high prevalence of helminth parasites 1,10,13,14,15,22,24,25 . The study results obtained in Guarulhos, where approximately 75% of districts had contaminated the soil with parasites responsible for zoonoses, indicate that the majority of the municipal population is at zoonotic risk.…”

“…Despite the high incidence of larva migrans syndromes in various regions, few studies have assessed soil contamination in large urban centers 3,10,14,15,18,37,39 . For example, in Guarulhos, a metropolitan area of São Paulo (São Paulo State, Brazil), there is little analysis of soil contamination by helminths that cause zoonoses.…”

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.

“…Human infection is acquired through the ingestion of embryonated Toxocara eggs (eggs reach the environment via canid or felid stools and become infectious for humans and other hosts over the course of a few weeks). Dubná et al (2007a) reported an 11.90 % prevalence of Toxocara eggs in 126 composite samples taken from child sandpits in Prague (Czech Republic). In paratenic hosts, such as humans and mice, hatched larvae migrate systematically throughout the body and have the ability to reach critical sites such as the eyes and central nervous system.…”

SummaryWe determined the prevalence of primarily zoonotic parasites in the small intestines of 40 (20 males and 20 females) red foxes living near human dwellings. The total prevalence of parasite infection was 77.5 % (31/40); the prevalence was 37.5 % (15/40) for Toxocara canis and 35 % (14/40) for Toxascaris leonina. The mean intensity infection was 3 and 11 helminths for T. canis and T. leonina, respectively. The prevalence of other intestinal helminths and mean infection intensity in this study are given: Echinococcus multilocularis 40 % (16/40) with 1000 individuals, Mesocestoides spp. 40 % (16/40) with 8 individuals, Uncinaria stenocephala 10 % (4/40) with 8 individuals, and Taenia pisiformis 10 % (4/40) with 1 individual. With regards to prevalence and intensity of infection, as well as prevalence of individual parasites, there were no signifi cant differences (P≥0.05) between male and female red foxes.

“…La mayoría de los estudios en este ámbito revelan presencia de helmintos zoonóticos, especialmente Toxocara sp., en plazas [4][5][6][7] . Estas zoonosis, transmitidas principalmente por animales de compañía, son un problema importante para la salud pública, dada la alta frecuencia de perros vagos y callejeros [8][9][10] , los cuales defecan en áreas públicas, facilitando la transmisión de parásitos a humanos.…”
