Abstract
In Colombia, there are very few studies about intestinal parasitosis in dogs, and street dogs constitute a high-risk group for the acquisition of parasitic zoonotic diseases. Through a cross-sectional descriptive study carried out in 2014, the prevalence of intestinal parasitosis and its associated factors were determined in 68 dogs of both sexes from two animal welfare centers in Medellin and eastern Antioquia (Colombia). The parasitological diagnosis was made by direct examination with saline solution at 0.8% and iodine, and the Sheather flotation method. The overall prevalence of intestinal parasitosis was 72.1% (49), helminths 58.8% (40), protozoa 33.8% (23) and parasitism in 45.6% (31). 11 parasitic agents, of which the most prevalent were <em>Uncinaria stenocephala</em> with 39.7% (27), were identified <em>Ancylostoma caninum</em>, with 20.6% (14) <em>Trichuris vulpis</em>, with 16.2% (11) and <em>Toxocara spp.</em>, with 11.8% (8). These were statistically higher in eastern Antioquia (p value chi<sup>2</sup> < 05). <em>Taenia spp.</em> presented a prevalence of 4.4% (3) and it was higher in Medellin. There was no association between the prevalence of each taxon to sex or age (p value > 0.05). A high prevalence of intestinal parasitism in dogs from Medellin and eastern Antioquia was evidenced, as well as a great diversity in the prevalence of the subgroups studied. This information highlights the need to promote research in order to determine the magnitude and associated factors in specific populations as the foundation for targeting actions on veterinary health and public health, given the zoonotic potential of some parasitosis of dogs.
