Occurrence and Morphometric Characterization of <i>Cysticercus tenuicollis</i> in Sheep From Minas Gerais, Brazil. [PDF]

Vet Med Int
In livestock production, the health of slaughtered animals is crucial to ensuring food safety. In this context, animal cysticercosis poses serious problems within production systems. Cysticercosis caused by Cysticercus tenuicollis (larval stage of Taenia hydatigena) is common in pasture‐raised ruminants.
