RESUMO:

The objective of this study was to describe the occurrence of outbreaks of spontaneous intoxication due to the consumption of Prosopis juliflora pods in cattle and goats in the State of Bahia. The history of ingestion of "mesquite beans" pods along with classic clinical signs of the "jaw and tonque trouble" and epidemiological data of the four outbreaks were obtained from technical visits, with the assistance of Veterinary Doctors of the CDP / UFBA and UFRB responsible for the visits and by rural staff. The first outbreak (PS) occurred in May 2011 at a property located in the municipality of Juazeiro and affected a herd of 150 goats. The Second Surge (SS) occurred in February 2015 in the municipality of Iaçu and reached a herd composed of 20 goats. The third outbreak (TS) occurred in July and September 2014, in a rural property located in the municipality of Tucano and affected a herd of 30 cattle. The Outbreak Room (QS) happened in August of 2016, in a property consisting of a herd of 110 cattle. Of the seven animals that presented a severe clinical condition and poor prognosis, six were euthanized and necropsied for diagnostic confirmation, four goats (C1-PS, C2-PS, C3-SS and C4-SS) and two bovines (B1-TS and B2 -TS), a bovine (B3-QS) was not allowed its euthanasia. During necropsy samples of the CNS and masseter muscle fixed in 10% formalin were collected. The clinical findings (PS, SS, TS and QS) and histopathological findings (PS, SS and TS) verified in the outbreaks reported here were compatible with algaroba intoxications. Clinically we observed mainly progressive weight loss, atrophy of chewing muscles, pendulous mandible, tongue protrusion, difficulty in seizing and chewing food, tilting of the "jaw and tonque trouble" head during chewing or rumination and excessive salivation. In the laboratory tests of the animals evaluated (C3-SS, C4-SS and B3-QS) anemia and hypoproteinemia were observed. At necropsy he observed cachexia, atrophy, paleness of the masseter muscle and recognizable fragments of "mesquite beans" pods. Histologically, it observed degeneration of the motor nucleus of the trigeminal nerve and atrophy by denervation of the masseter muscle with replacement by fibrous tissue. Control measures and prophylaxis of intoxication and management with "algaroba", it is discussed the need to develop research to determine the economic viability and sustainability of the algaroba exploiting its forage potential (animal feeding and commercialization of pods) and timber (production of firewood, coal, cuttings and mourners). P. juliflora intoxication with necroscopic and histopathological record in cattle and goats was reported for the first time in BA. Showing to be an important disease for both species in the State.
