Abstract: The frequency of parasitic contamination of public areas in the municipality of Pelotas, state of Rio Grande do Sul, Brazil, was studied between June 2010 and May 2011, when soil samples were collected from eight city squares. Out of 400 samples submitted to centrifugal floatation technique in solution of sodium dichromate with density of 1.35, 176 (44%) proved positive for at least one parasite; 29 (16.5%) samples were multi-infested. The results showed that there was a significant soil contamination rate in … Show more

“…eggs in 8.19% of samples is like that of other soil studies developed in Pelotas, which also observed the presence of this parasite in 14.7% to 3% of the samples analyzed (TAVARES et al, 2008;VILLELA et al, 2009;MOURA et al, 2013), making the presence of this helminth in the municipality important. Trichuris vulpis is a ubiquitous parasite with high infection rates in domiciled and non-domiciled animals (TRAVERSA, 2011).…”

“…eggs were less frequent compared to other studies carried out in the municipality of Pelotas, where Villela et al (2009) observed 24.1% of positive samples on the banks of Laguna dos Patos. Gallina et al (2011) demonstrated it was the most frequent parasite egg (62%) in the soil samples of a University Campus, while Moura et al (2013) found that it was the second most observed parasite in public areas, confirming the presence in 8.8% of the samples analyzed. Eggs of Toxocara spp.…”

“…Infection by A. lumbricoides associated with other immunosuppressive diseases has been described in other studies and may be related to a wide prevalence of this helminth in humans around the world (Lau et al, 2007;Brum et al, 2013). It is worth mentioning that eggs of this helminth have been found in public parks within city limits, which is suggestive of a considerable risk of infection and its high prevalence among the local human population (Moura et al, 2013).…”

“…Environmental contamination by these parasites has been detected in the City of Pelotas, both in student environments 9 and in the public square 10 . Therefore, children may be exposed to environments that favor parasitic infection as the eggs of these nematodes are common environmental contaminants and present high resistance under different climatic conditions.…”
