Abstract

Sida carpinifolia is a plant responsible for poisoning several species of animals. This paper describes Hypomyelinogenesis in fetuses and neonates of cattle that consumed S. carpinifolia. Neonates manifested ataxia and muscle tremors. Two bovine newborns and four fetuses were necropsied and showed no significant gross changes. Histopathologic findings included vacuolation of pancreatic acinar cells, thyroid follicular cells, hepatocytes, cells of renal tubules and neurons of the fetus and the white matter of the telencephalic frontal lobe of the neonates and also revealed axonal spheroids in the brain of the fetuses and neonates. The lectin-histochemical evaluation shoved staining for the lectins Con-A, WGA and s-WGA. The Luxol Fast Blue staining revealed a marked decrease of myelin in the brain of all the fetuses and a moderate decrease in the neonates. Histologic and lectin-histochemic findings indicate that the consumption of S. carpinifolia by pregnant bovine females can cause hypomyelinogenesis in fetuses and neonates. RESUMO: Sida carpinifolia é uma planta responsável por intoxicar várias espécies animais. Este artigo descreve hipomielinogênese em fetos e neonatos de bovinos que consumiram S. carpinifolia. Os neonatos manifestaram ataxia e tremores musculares. Dois neonatos e quatro fetos bovinos foram necropsiados e não havia alterações macroscópicas significativas. Os achados histopatológicos incluíram vacuolização de células acinares do pâncreas, células foliculares da tireoide, hepatócitos, células renais tubulares e neurônios nos fetos. Nos neonatos havia vacuolização na substância branca do lobo frontal telencefálico, além de esferoides axonais no encéfalo dos fetos e dos recém-nascidos. A avaliação lectino-histoquímica demonstrou marcação para as lectinas Con-A, WGA e s-WGA. A coloração de Luxol Fast Blue revelou diminuição acentuada da mielina no telencéfalo de todos os fetos e diminuição moderada nos neonatos. Os achados histológicos e lectina-histoquímicos indicam que o consumo de S. carpinifolia por fêmeas bovinas gestantes pode causar hipomielinogênese em fetos e neonatos.

Abstract

Sida carpinifolia is a small subshrub that is distributed throughout Brazil and is responsible for lysosomal storage disease and occasional reproductive problems in cattle, goats, equids, sheep, and deer. We describe herein the clinical, epidemiologic, and pathologic features of hydrallantois in 3 cows naturally poisoned by S. carpinifolia in Rio Grande do Sul State, Brazil. Clinically, all cows had marked abdominal distension and mild ataxia. After natural death or euthanasia, autopsies revealed that the abdominal distension in all 3 cases was caused by severe enlargement of the uterus, which contained 100–120 L of translucent fluid within the allantois, in addition to adventitial placentation. Microscopic evaluation of the placenta revealed marked diffuse edema, sometimes with a myxomatous appearance. Neurons in the cerebellum and obex were swollen, with mild-to-moderate cytoplasmic granular vacuolation. Histochemical examination with lectins ConA, WGA, and sWGA revealed mild-to-marked staining in the cytoplasm of neurons of the cerebellum and medulla at the level of the obex, indicating the occurrence of α-mannosidosis.
