In the world, Kalanchoe species are primarily ornamentals and houseplants, but some have escaped cultivation and can be found in the field. In Latin America, there are no reports of spontaneous poisoning by Kalanchoe species in animals. This study aimed to describe the epidemiological, clinical, and pathological aspects of an outbreak of poisoning by Kalanchoe blossfeldiana in cattle in the semiarid region of Pernambuco, Brazil. Epidemiological and clinical data were obtained from the owner and veterinarian during technical visits. Prunings of this plant were disposed of in a pasture with a shortness of forage. Seventeen cattle had clinical signs, and thirteen died 4-5 days after the first clinical signs were observed. Clinical signs and gross and histological lesions include gastrointestinal, cardiovascular, and neuromuscular disorders. Kalanchoe spp. contain cardiotoxic glycosides, and the clinical signs and lesions in cattle of this outbreak were consistent with poisoning by plants that contain these toxins.
在世界范围内，伽蓝菜属植物主要作为观赏植物和室内植物，但有些已经逸出栽培范围，能在野外发现。在拉丁美洲，没有关于伽蓝菜属植物致使动物发生自发性中毒的报道。本研究旨在描述巴西伯南布哥州半干旱地区牛群因长寿花中毒暴发的流行病学、临床和病理学特征。通过技术走访从畜主和兽医处获取流行病学和临床数据。这种植物的修剪枝条被丢弃在草料短缺的牧场。17头牛出现临床症状，其中13头在首次观察到临床症状后的4至5天死亡。临床症状以及大体和组织学病变包括胃肠道、心血管和神经肌肉紊乱。伽蓝菜属植物含有心脏毒性苷类，此次暴发中牛的临床症状和病变与含有这些毒素的植物中毒相符。
