Publication Type: Peer Reviewed Journal Publication Acceptance Date: 8/26/2016 Publication Date: 2/1/2017 Citation: Almeida, V.M., Rocha, B.P., Pfister, J.A., Medeiros, R.M., Riet-Correa, F., Chaves, H.A., Silva Filho, G.B., Mendonca, F.S. 2017. Spontaneous poisoning by Prosopis juliflora (Leguminosae) in sheep. Pesquisa Veterinaria Brasileira. 37(2):110-114. Interpretive Summary: The aim of this paper is to describe the first report of clinical, epidemiological and pathological aspects of spontaneous poisoning by Prosopis juliflora in sheep. Of a total of 500 sheep at risk, two adult male sheep were affected; one died spontaneously and the other animal was examined, euthanized and necropsied. Neurologic examinations focused particularly on motor and sensory-cranial nerve functions. Complete blood counts, serum biochemistry and urinalysis were done. The biochemistry revealed a significant increase in serum creatine phosphokinase level. The evolution of the disease was chronic and before sheep showed signs of poisoning, sheep had to ingest a diet containing at least 80% of P. juliflora pods during 21 months. Clinical sign includes drooling of saliva, dropped jaw, tongue protrusion and loss of food from the mouth. Gross and histological lesions were similar to those previously reported in cattle and goats. There is no specific treatment for P. juliflora poisoning in ruminants. Sheep are quite resistant to poisoning considering that it took 21 months of pod consumption for two out of 500 sheep to show clinical signs. Technical Abstract: The aim of this paper is to describe the first report of clinical, epidemiological and pathological aspects of spontaneous poisoning by Prosopis juliflora in sheep. Of a total of 500 sheep at risk, two adult male sheep were affected; one died spontaneously and the other animal was examined, euthanized and necropsied. Neurologic examinations performed focused particularly on motor and sensory-cranial nerve functions. Complete blood counts, serum biochemistry and urinalysis were made. The biochemistry revealed a substantial and severe increase in creatine phosphokinase level. The evolution of the disease was chronic and to present signs of poisoning, sheep had to ingest a diet containing at least 80% of P. juliflora pods during 21 months. Clinical sign includes drooling of saliva, dropped jaw, tongue protrusion and loss of food from the mouth.
