In this paper, plants causing mechanical injury to ruminants and horses in Brazil are reviewed, and an outbreak in sheep of mechanical injury of the skin by Stipa sp. in Uruguay is reported. The sheep, mainly lambs, showed large number of fruits of Stipa sp. in the wool, some of them penetrating the skin, panniculus adiposus, and cutaneous trunci muscle, causing multifocal dermatitis and panniculitis.
