title: Echinococcus granulosus sensu lato and Taenia hydatigena in pig in southern Brazil.
abstract: This study aimed to identify the parasitical etiologic agents of visceral cysts in pigs from the central/northern region of Rio Grande do Sul State, Brazil. Fifty-eight cysts were found in livers during veterinary inspection of swine slaughtered from January 2008 to 2012. Collected samples were submitted to macroscopic and molecular analyzes. Polymerase chain reaction (PCR), DNA sequencing and BLAST alignment of sequences was used to molecular characterization of the samples. By PCR 10.3% (6/58) of tested samples were positive for Echinococcus granulosus sensu lato and 56.9% (33/58) for Cysticercus tenuicollis. In this study, it was verified the occurrence of larval forms of E. granulosus sensu lato and Taenia hydatigena in pig herds from the central/northern region of Rio Grande do Sul State. The presence of both parasites is relevant due to the economic losses for the meat industry. Additionally, E. granulosus sensu lato has zoonotic importance and may be infecting pig herds in southern Brazil.
