Mortality supposedly due to intoxication by pyrrolizidine alkaloids from heliotropium indicum in a horse population in costa rica: a case report
This article describes a case of massive mortality among horses which was probably due to intoxication by pyrrolizidine alkaloids from Heliotropium indicum. Over 4 years more than 75% of a population of about 110 horses on a farm in Costa Rica died after showing nervous neurological symptoms. Two cl...

Este artículo describe un caso de mortalidad masiva entre caballos que probablemente se debió a la intoxicación por alcaloides pirrolizidínicos de Heliotropium indicum. A lo largo de 4 años, más del 75% de una población de unos 110 caballos en una finca de Costa Rica murió tras mostrar síntomas neurológicos nerviosos. Se encontraron dos manifestaciones clínicas, una aguda y otra crónica, ambas con desenlace fatal. Los hallazgos patológicos en 2 caballos coincidieron con los reportados en la literatura para la intoxicación por alcaloides de pirrolizidina y no fueron específicos para la EEV. Sin embargo, la encefalitis equina venezolana (EVE) fue el principal diagnóstico diferencial y no pudo excluirse por completo, ya que esta enfermedad era endémica en la región y los títulos de EVE resultaron ser elevados. Las investigaciones taxonómicas y toxicológicas implicaron al Heliotropium indicum como la causa principal más probable de la intoxicación.
