Gastrointestinal parasitosis among humans and their domestic dogs in an urban-marginal community in Ecuador and risk to public health ; Parasitosis gastrointestinales entre humanos y sus perros domésticos en una comunidad urbano-marginal de Ecuador y riesgo en salud pública

The objective of this study was to record gastrointestinal parasitic zoonoses between humans and their domestic dogs, and thus correlate the risk in Public Health, in an urban-marginal community called “Las Piñas”, belonging to the Milagro canton (Guayas-Ecuador). Samples of humanfeces and their domestic dogs were analyzed through of coproparasitic tests. From 201 human fecal samples and 257 canines, total prevalences of intestinal parasitosis in humans were determined to be 48.25% and in domesticdogs 74.32%. Seven taxa of parasites were identified in humans: Entamoeba histolytica 30.84%, Entamoeba coli 13.93%, Giardia lamblia 7.96%, Ascaris lumbricoides 3.98%, Trichuris trichiura 3.98%, Ancylostoma spp. 2.48% y Stron-gyloides stercoralis 1.49%. On the other hand, the following nine parasites species were identified in canines: Ancylostoma spp. 73.82%, Toxocara canis 36.64%, Strongyloides stercoralis 26.17%, Trichuris vulpis 4.18%, Cystoisospora spp. 1.57 %, Dipilidium caninum 1.04 %, Opisthorchis spp. 1.04 %, Alaria spp. 0.52% y Echinococcus granulosus 0.52%. The parasite that coincided betweenhumans and their domestic dogs was Strongyloides stercoralis. The importance for humans and canines is that some of the species found in canines are zoonotic (Ancylostoma caninum and A. braziliense, T. canis, D. caninum; E. granulosus, A. alata, T. vulpis) and some found in man it can share them with the canines (S. estercoralis, G. lamblia, some species of Opisthorchis). ; El presente estudio tuvo como objetivo registrar parasitosis gastrointestinales entre humanos y sus perros domésticos, y así correlacionar el riesgo en Salud Pública, en una comunidad urbano-marginal denominada “Las Piñas”, perteneciente al cantón Milagro (Guayas-Ecuador).
