A cross-sectional study of free-roaming dogs in a Patagonian city: Their distribution and intestinal helminths in relation to socioeconomic aspects of neighborhoods

Human and dog health are inextricably linked, and although our relationship with dogs brings numerous benefits for our well-being, it is known that they can transmit disease. Bariloche is a Patagonian tourist city with heterogeneous social composition. This cross-sectional study evaluates the population of free-roaming dogs and their intestinal parasites in relation to the socioeconomic level of the city's human population. Census areas were used as survey units, stratified in three levels according to socioeconomic status. The free-roaming dog population was estimated by walking around each census area. Eight fresh feces per census count area were collected and analyzed using coproparasitological flotation tests, and CoproELISA was used to detect Echinococcus sp. A total of 858 free-roaming dogs were registered along 40.9 km, with significant differences between socioeconomic strata: the highest numbers were found in the lowest income strata. Of the feces collected, 39.2% tested positive for parasites, those associated with a lower socioeconomic level having higher percentages of positive feces and a greater number of species. Eight species of helminths were found, some of which were zoonotic, such as Echinococcus sp., Toxocara canis, and Dibothriocephalus latus. The presence of parasites can be explained by the number of free-roaming dogs per census count area. The free-roaming dogs generally have owners, and their parasitic infection is strongly associated with the socioeconomic level of the population. The main problem is irresponsible pet care, which generates healthy conditions for both dogs and humans. Thus, both dogs and humans deserve effective ethical public policies.
