Sinais clínicos e patologia da intoxicação crônica experimental de caprinos por Palicourea marcgravii

Abstract: RESUMO.-Palicourea marcgravii é considerada a principal planta tóxica de interesse pecuário no Brasil, porém, até o momento, é conhecido apenas o quadro agudo da intoxicação. Esse estudo avaliou as alterações clínico-patológicas de 10 caprinos cronicamente intoxicados por P. marcgravii. Os animais receberam, diariamente, 0,2g/kg de peso corporal da planta fresca por 6 a 38 dias. Os caprinos apresentaram como principais sinais clínicos anorexia, apatia, taquicardia, arritmia, pulso venoso jugular positivo e dec… Show more

“…Intracellular edema and coagulation necrosis of small groups of cardiac fibers were reported in 1985 in poisoning by Amorimia rigida, but it never was investigated as the possible cause of sudden death (Tokarnia et al 1985). Goats chronically intoxicated with Palicourea marcgravii exhibit vacuolization of cardiomyocytes, necrosis of cardiac fibers and mononuclear cell infiltration (Barbosa et al 2015). Myocardial coagulation necrosis in groups of cardiomyocytes has recently been reported as a frequent finding in cases involving two others plants that induce sudden death in ruminants, Pseudocalymma elegans (Helayel et al 2009) and Amorimia spp (Schons et al 2011).…”
