Abstract:
Poiretia punctata (Willd.) Desv. was associated with cattle and sheep poisoning on nine farms in the State of Sergipe, northeastern Brazil. The animals were found dead or died later after showing clinical signs for up to 18 hours. Two sheep that ingested 40g/kg body weight (g/kg) of fresh P. punctate died three and eight hours after ingestion, respectively. Another sheep that ingested 40g/kg five days after plant collection showed mild clinical signs and recovered after 24 hours. Two sheep that received 20g/kg and another that ingested three daily doses of 20g/kg showed clinical signs, but recovered. Two cattle that ingested 20g/kg of the fresh plant exhibited clinical signs and recovered. The clinical observations of poisoning were depression, ataxia, loss of equilibrium, broad-based stance, head down, falls, mandibular trismus, opisthotonous, nystagmus, and recumbence. Significant gross and histologic lesions were not observed. Samples of P. punctate were analyzed for nitrates, cyanogenic glycosides, and sodium monofluouracetate with negative results. It is concluded that P. puncatata is a toxic plant that caused death in cattle and sheep in the State of Sergipe.
