Inquérito parasitológico em cães com tutores da cidade de Porto Alegre, Rio Grande do Sul (2013-2019)

Dogs a reservoir hosts for helminth and protozoan species and cohabitation with humans plays a key role in zoonotic transmission. The aim of this study is to report the prevalence of intestinal helminths and protozoa and stablish the principal endoparasites in domestic dogs in the city of Porto Alegre, Rio Grande do Sul. Fecal samples were collected from 1400 dogs during the years 2013-2019 and analyzed at the Helminths Laboratory of the Faculty of Veterinary Medicine at the Federal University of Rio Grande do Sul. In total, 316 (22,6%) samples were positive for the least one parasite genus, with rates of 62,4%, 43,8%, 23,8%, 14,6%, 8,8%, 18,3% and 30,8%, respectively for the years 2013, 2014, 2015, 2016, 2017, 2018 and 2019. The positivity rate for monoinfected dogs was 86,4% (273/316) and 13,6% (43/316) for polyparasited dogs, especially Ancylostoma spp. The results reinforce the need to improve intestinal parasite control programs to protect dogs and humans and the need to increase the knowledge of dog tutors on the subject.
