ESTUDIO EPIDEMIOLÓGICO DE PARÁSITOS EN HECES DE PERROS EN PARQUES DE COZUMEL, QUINTANA ROO, MÉXICO

<p><strong>Background: </strong>Contamination of public spaces with canine feces containing parasites increases the possibility of transmission of these parasites to people and other canines. <strong>Objective: </strong>To estimate the frequency and variables associated with parasite eggs/oocysts in canine feces collected in public parks from Cozumel Island, Mexico. <strong>Material and methods:</strong> One hundred and fifteen stool samples were collected in 23 public parks, which were selected by convenience and analyzed by direct smear microscopy. The variables evaluated were i) with/without tourism, ii) low/high economic level), iii) high/low number of inhabitants and iv) area collection site paved/unpaved. A statistical association analysis test (Χ<sup>2</sup>) was performed to determine significance of results and the odds ratio (OR) between the studied variables was evaluated. <strong>Results: </strong>A parasite prevalence of 27% was found, recording the following order of species <em>Ancylostoma</em> spp > <em>Trichuris</em> spp > <em>Toxocara </em>spp > <em>Isospora</em> spp = <em>Taenia </em>spp. Statistical significance was not found in the X<sup>2</sup> tests and ORs. The positive sample frequencies of the variables evaluated did not show any correlation, irrespective of the parasite reported. <strong>Implications:</strong> Stray dogs, pet dogs, people and pet owners visiting public parks of Cozumel Island, Mexico, could be infected by gastrointestinal parasites. <strong>Conclusion:</strong> In public parks from Cozumel Island, gastrointestinal parasite eggs/oocysts are present in canine feces. However, the variables evaluated did correlate with the presence of these parasites.</p>
