Summary:The cystic echinococcosis (CE) is an important zoonotic disease caused by the parasite Echinococcus spp. In Brazil, this parasite is present in Rio Grande do Sul (RS) state, border with Argentina and Uruguay, causing several damages to human and animal health. This study aimed to identify Echinococcus spp. in hydatid cysts of swine and evaluate the similarity of the genotypes through the phylogenetic analysis. A total of 3,101,992 swine were slaughtered in the central/northern region of RS/Brazil, during 2008–2012. Five isolates were characterized as hydatid cyst by molecular analysis, based on the mitochondrial gene cytochrome c oxidase subunit I (cox-I). The genotypes E. granulosus sensu stricto (G1) (n=2) and E. canadensis (G7) (n=3) were identified in the hydatid cysts. The swine represents a potential intermediate host for different genotypes of Echinococcus spp., besides it can contribute to the perpetuation of the parasite's life cycle in rural areas.
