ABSTRACT
Public parks are leisure environments widely used by both, adults and children, often accompained by their pets. Soil contamination of these environments by enteric viruses and intestinal parasites occurs through these animals feces. The aim of this work was to detect Carnivore protoparvovirus 1 (CPV-1) and different species of Mastadenovirus in soils samples from a park located in a medium-sized city in Brazil and evaluate the presence of helminth eggs and larvae in 18 points of a public park soil samples, as well as feces found on this site during six months. Parasitological analyzes were conducted through flotation and sedimentation techniques, and polymerase chain reaction (PCR) was used for viral detection. Of the 216 soil and 16 feces samples, 49% (106/216) and 12% (2/16) were positivefor nematodes larvae, respectively, through sedimentation techniques. Toxocara spp eggs were found in one soil sample and one feces sample, Trichuris spp eggs were found in only one feces sample and Hookworms eggs were found in four soil samples. After reconstruction work in the streets near the park, 30% (64/216) of the samples were positive for Human Mastadenovirus C (HAdV-C), 1.4% (3/216) for HAdV-E and 0.4% (1/216) for Canine Mastadenovirus A (CAdV-A). The parasitic forms found in this study have demonstrated that the contamination of the park's soil pose a threat to human and animal health. This was the first study to report the presence of HAdVs and CAdVs in soil samples.
