Diminazene aceturate is a synthetic chemotherapeutic drug commonly used in veterinary medicine for the treatment of diseases caused by hematozoan parasites. However, side effects as severe neurological disorders and death can occur. The raising of american camelids is a recent activity in Brazil, requiring knowledge about diseases that affect these species, in order to avoid misguided conducts. In a herd of ten camelids (six llamas and four alpacas) six showed clinical signs and five died; only a llama with mild signs recovered. The clinical signs included apathy, difficulty to stand up, staggering gait, weakness, down head and drooping the head laterally, dyspnea and drooling of saliva, observed from 18 hours after use of the drug. At necropsy and histopathological examination was found bilateral and symmetrical hemorrhagic encephalopathy, more severe in brainstem and thalamus. This paper describes the main lesions observed in an outbreak of diminazene aceturate poisoning in alpacas (Lama pacos) and llamas (Lama glama) and alert breeders and veterinarians about the risk of poisoning by this drug in american camelids. |
