Summary 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 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., Toxocaracanis, and
Dibothriocephalus latus. The presence of parasites can be
explained by dog size and the number of free-roaming dogs per block. 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 bad
conditions for both dogs and humans. Thus, both dogs and humans deserve
effective and ethical public policies.
