Chronic Heart Failure and Abortion Caused by Tetrapterys spp. in Cattle in Brazil

摘要

Several cardiotoxic plants in the world cause different clinical-pathological syndromes due to numerous active principles. In Brazil, there are many plants that cause sudden death (Brazilian sudden death causing plants; BSDCP) which may have sodium monofluoro-acetate (MF) as a toxic principle (Tokarnia et al. 2000; Peixoto et al. unpublished data). This group of plants is responsible for the death of at least 600,000 cattle per year in Brazil (Tokarnia 2009, personal communication). In general, the animals poisoned by BSDCP do not develop heart lesions and the clinical evolution usually lasts only a few minutes.
