Intoxicação por Trema micrantha (Ulmaceae) em caprinos no Estado de Santa Catarina

Abstract: Vinte e cinco caprinos, criados em piquetes, morreram nos cinco dias subsequentes ao fornecimento de folhas de Trema micrantha (fam.Ulmaceae), uma árvore com nome comum de grandiúva. Quatro caprinos foram necropsiados e amostras de vísceras foram coletadas para exame histológico. As principais alterações clínicas foram: apatia, anorexia, cabeça apoiada contra obstáculos, decúbito e morte. Achados macroscópicos incluíram sufusões no epicárdio e endocárdio; fígado levemente amarelado e com padrão lobular evident… Show more

“…Poisoning by T. micrantha has been reported in other herbivores; however, the reports were focused on the hepatotoxic effects. 2,5,16 Although ingestion of T. micrantha was associated with hepatic necrosis in sheep, the most striking finding in this study was pneumotoxicosis, similar to that in acute respiratory distress syndrome, which is characterized by acute onset, severe hypoxemia, and diffuse alveolar damage with proteinic edema and hyaline membrane formation. 3,8 In South Africa, ingestion of Crotalaria globifera and Crotalaria dura has been associated with pulmonary adenomatosis of sheep and horses.…”

“…9 T. micrantha leaves are highly palatable and readily consumed by herbivores. Ingestion of this plant has been associated with poisoning in goats 5,16 and horses. 2 Poisoning by T. micrantha is characterized predominantly by acute hepatic insufficiency due to centrolobular hepatic necrosis 16 and is often accompanied by neurologic signs 2 of hepatic encephalopathy.…”

“…Os achados de evidenciação do padrão lobular do fígado e hemorragias multifocais a difusas em fígado e serosas na intoxicação por C. intermedium são também descritos em outras hepatopatias tóxicas agudas em bovinos no Brasil (Santos et al 2008, Riet-Correa et al 2009, Tokarnia et al 2012, como na intoxicação por C. corymbosum (Gava et al 1991, Varaschin et al 2011, C. laevigatum (Döbereiner et al 1969), C. parqui (Riet-Correa et al 1986), Dodonaea viscosa (Colodel et al 2003), Myoporum laetum (Méndez 1993), Sessea brasiliensis (Canella et al 1968), Vernonia mollissima (Döbereiner et al 1976), Vernonia rubricaulis (Tokarnia & Döbereiner 1982, Brum et al 2002 e Xanthium strumarium, também identificado como Xanthium cavanillesii (Méndez et al 1998, Driemeier et al 1999; de forma que devem ser consideradas no diagnóstico diferencial. Dessas plantas, são registradas no estado do Paraná, além de C. intermedium, as plantas hepatotóxicas C. corymbosum (Kissmann & Groth 2000, Lorenzi 2008a), Trema micrantha (Lorenzi 2008b) Xanthium strumarium (Kissmann & Groth 2000, Tokarnia et al 2012.…”

“…Como os sinais clínicos e lesões macroscópicas e microscópicas em parte são semelhantes às produzidas por plantas de ação hepatotóxica aguda. No diagnóstico diferencial devem ser consideradas as intoxicações por: Dodonea viscosa, encontrada principalmente na região litorânea (Cattani et al 2004), Cestrum intermedium (Gava et al 1996, Furlan et al 2008) encontrada na região Oeste dos três estados do sul, Cestrum corymbosum encontrada no Planalto e Alto Vale do Itajaí (Gava et al 1991) e Xanthium cavanillesii (Driemeier et al 1999, Colodel et al 2000. Também deve ser considerada a intoxicação por larvas de Perreyia flavipes (Soares et al 2008).…”
