Soil contamina- tion with dog faeces is an important worldwide problem because it facilitates the transmission of zoonotic parasites. It has been reported in different studies that soil contamination by parasites represents a risk factor for the population (mainly children) to acquire parasitic diseases caused by Dipylidium caninum , Ancylostoma spp., and Trichuris spp. Therefore, the objectives of the present study were to analyse soil samples collected from fi ve public parks in the city of Nezahualcoyotl, Mexico for the presence of canine soil-transmitted parasites. Materials, Methods & Results : A total of 1726 soil samples were obtained from fi ve public parks in Nezahualcoyotl County, Mexico and analysed for Dipylidium caninum , Ancylostoma spp., and Trichuris spp. eggs. Sampling was carried out in summer 2009 with the permission of the Parks and Public Gardens Nezahualcoyotl Offi ce. Samples were evaluated using a fl otation method, using microscopic observation for egg identifi cation. The data were analysed with the Kruskal- Wallis test and average mean percentages of contamination between the parks means were compared using the Nemenyi test. There were differences in the degree of contamination among the parks, but the soil characteristics were not correlated with the presence of parasite eggs. Contamination with Dipylidium caninum and Trichuris spp. were positively correlated (r = 0.32, P < 0.0001). Overall, there was a substantial frequency of Ancylostoma spp. (23.7%) and Dipylidium caninum (21.7%), with minor presence of Trichuris spp. (15.3%) in the parks. Discussion : Several studies have shown that the close relationship between resulting from the human-animal bond provides benefi ts for socialisation, mental health, and even physical well-being. However, owning a pet also allows potential health risks for the human population. Incidence studies of parasites in the soil of public parks provide greater insight regarding their zoonotic potential, and revealed that the soil of public parks is a source of infection and transmission of parasitic diseases. The reports on soil parasites contamination vary depending on where in the in the world were conducted. Studies in Brazil and Argentina had twice the levels of contamination for Ancylostoma spp. eggs andlower levels of D. caninum . However, the degree of contamination for Trichuris spp. in this report was higher than that observed in public parks in other countries (Croatia, Nigeria, and Brazil). These studies indicate that the risk of acquiring a zoonotic parasitic infec- tion is extremely high, since the soil is highly contaminated with infectious eggs of parasites. The study of the prevalence of parasites in dogs and understanding of the life cycle, epidemiology, and risk factors involved require the establishment of prevention programs for public health reason. Therefore, it is important to implement measures for the collection of excreta in public parks and promote dog deworming programs and hygiene measures to prevent infection in paratenic hosts. The results of this research revealed that the soil of public parks were a source of parasitic zoonoses, because dogs play an important role in the contamination of soils by excreting intestinal parasites through their faeces, constituting a public health problem. | URI: | http://ri.uaemex.mx/handle20.500.11799/40251 | Other Identifiers: | http://hdl.handle.net/20.500.11799/40251 | Rights: | info:eu-repo/semantics/Acta Scientiae Veterinariae info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0 |
