Abstract

Abstract This chapter reports spontaneous outbreaks of poisoning by Solanum paniculatum in cattle in the state of Pernambuco and experimental reproduction of the intoxication in cattle in the states of Pernambuco, Paraíba, and Rio Grande do Sul. The outbreaks occurred during a 3-year period between September 2005 and December 2008 in 3 counties (Brejão, Pesqueira, and Poção) in the Agreste region (transition between the lush, rainy coast and the semiarid region of the deep interior) of the state of Pernambuco, affecting 2- to 5-year-old Holstein and Brown-Swiss cattle and their crosses used for milk production. Based on the epidemiological data, clinical signs, and histological lesions observed in spontaneous cases and in the experimental reproduction of similar clinical signs and lesions, we conclude that the disease observed in the state of Pernambuco is caused by the ingestion of S. paniculatum.
