Parasitic infections in humans and animals

Many parasitic infections can be transmitted from dog to man, which constitutes a risk to public health worldwide.The aim of this study was to report any presence of parasite eggs in soil samples from 87 parks and public places in 6 areas of the city of Temuco, located between 37° 24' and 39° 34'; latitude South, Region of Araucania, Chile.193 three soil samples were collected, and 70 positive samples (36.3%) were obtained by using the modified method of Fonrouge.In 48.3% of the parks, the eggs found corresponded to the genders Toxocara sp.(12.4%),Taenia sp.(11.4%) and eggs of Trichuris sp.(4.7%).Also, a set of eggs identified as Strongylid (9.3%) was found, but it was notpossible to determine whether they were parasites or free life helminthes.In addition, 2.8% of the samples showed polyparasitism.According to Fisher's exact test, there was no statistical association between the type of topsoil of the park and the type of contamination; and no differences were found between risk of infection and studied area.Results showed that parks and public places of Temuco are contaminated with parasite eggs mainly associated with dogs, posing a potential hazard to human health.
