| Descripción: | Plants of the genus Senna belong to the Fabaceae family and globally they are distributed in tropical and subtropical areas. Some species of this genus contain products of secondary metabolism, which have been associated with toxic myopathy and hepatic necrosis in different animal species. The goal of this case report was to document for the first time in Costa Rica myotoxicity in calves associated to the consumption of Senna cobanensis, a Senna species that had not been previously reported as myotoxic in the literature, which resulted in 4 affected animals out of 18 and 2 deaths out of the 4 affected. The case took place in a zebu cattle farm in the Central Pacific region of Costa Rica in December 2019. A clinical examination was conducted of the calves, and their diet was analyzed. Locomotor problems were found such as paraparesis and increased AST and CK-NAC activity consistent with muscle tissue damage. The histopathologic analysis revealed degeneration and necrosis of muscle fibers. Other myopathic agents such as selenium deficiency and ionophore intoxication were ruled out. According to the results obtained in the study, it is concluded that Senna cobanensis is another species of the genus that causes myotoxicity in cattle. |
