ABSTRACT.- Santos J.C.A., Riet-Correa F., Simões S.V.D. & Barros C.S.L. 2008. [Pathogenesis, clinical signs and pathology of diseases caused by hepatotoxic plants in ruminants and horses in Brazil.] Patogênese, sinais clínicos e patologia das doenças causadas por plantas hepatotóxicas em ruminantes e eqüinos no Brasil.

Plants causing hepatic lesions in ruminants and horses constitute one important group of poisonous plants in Brazil. These plants can be placed in three major groups: plants causing acute liver necrosis; plants causing liver fibrosis; and plants causing hepatogenous photosensitization. For some of these plants the toxic principles are known. Cestrum parqui and Xanthium cavanillesi that cause acute liver necrosis contain carboxy-atractylosides. Senecio spp., Crotalaria spp., and Echium plantagineum that cause liver fibrosis contain pyrrolizidine alkaloids. As for the group of plants causing hepatogenous photosensibilization, Myoporum spp. contain furanosesquiterpenes, Lantana spp contain triterpenes, and Brachiaria spp. and Panicum spp. contain steroidal saponins. The clinical and pathologic features of the toxicosis caused by these phytotoxins, general mechanisms of production for the production of the clinical signs and the methods for diagnosis of hepatic failure in farm animals are reviewed.
