Resumen:
Dog feces harbouring infective parasiticforms (larves, eggs, cysts of helminths and oocysts of protozoan) are potential sources of environmentalcontamination, representing a high risk of infection for people. The feces of 46dogs housed at the Municipal Centre of Zoonoses of Mar del Plata City were analyzed to determinethe prevalence of intestinal parasitic forms. The overall prevalence of parasites was89.13%. Detected parasites were Ancylostoma caninum (71.74%), Toxocara canis (63.04%),Trichuris vulpis (45.65%), Uncinaria stenocephala (41.30%), Capillaria aerophila (17.39%),Echinococcus granulosus (8.69%), Giardia spp. (10.87%) and Isospora spp. (2.17%). Thegeographical characteristics and the wet weather of the region under consideration, togetherwith the cultural habits and the socio–economic situation of the population may favor transmission.The prevalences of stray and domesticated infected dogs were 88% and 95.24%,respectively. Because stray dogs are often free–roaming, environmental contamination withparasite forms had likely already occurred. The prevalences of A. caninum and T. vulpiswere significantly higher in < 6 years–old dogs rather than in older animals. Parasite–specificimmunity is usually acquired during development, probably as a consequence of singleor repeated exposures. Multiple infections were more frequent (80%) than infections witha single parasite (20%) and the most common parasite association (21.87%) was among A.caninum, T. vulpis, T. canis and U. stenocephala. The high prevalence of poly–parasitizedanimals together with the zoonotic potential of the parasites found in the samples, indicatethat dog feces could be the source of several parasite infections for human as well as caninepopulations of the region under study. The parasite zoonoses transmitted by dogs are still asanitary problem in the District of General Pueyrredón.
