ABSTRACT.
This review updates information about cardiotoxic plants affecting ruminants in Brazil. Currently it is known that there are at least 131 toxic plants belonging to 79 genera. Twenty five species affect the heart function. Plants that contain sodium monofluoroacetate (Palicourea spp., Psychotria hoffmannseggiana, Amorimia spp., Niedenzuella spp., Tanaecium bilabiatum and Fridericia elegans) cause numerous outbreaks of poisoning, mainly in cattle, but buffaloes, sheep and goats are occasionally affected. Poisoning by Palicourea marcgravii remains the most important due to the wide distribution of this plant in Brazil. New species of the genus Palicourea containing sodium monofluoracetate, such as Palicourea amapaensis, Palicourea longiflora, Palicourea barraensis, Palicourea macarthurorum, Palicourea nigricans, Palicourea vacillans and Palicourea aff. juruana were described in the amazon region. In the northeast region, the most important toxic plant for cattle is Amorimia septentrionalis. In the midwest, outbreaks of Niedenzuella stannea poisoning have been reported in cattle in the Araguaia region and the disease needs to be better investigated for its occurrence and importance. Tetrapterys multiglandulosa and Tetrapterys acutifolia, two plants causing cardiac fibrosis also contain sodium monofluoroacetate and were reclassified to the genus Niedenzuella. These two plants and Ateleia glazioveana, other plant that causes cardiac fibrosis continues to be important in the southeastern and south of Brazil. Other less important are the plants that contain cardiotoxic glycosides, such as Nerium oleander and Kalanchoe blossfeldiana, in wich poisonings are generally accidental. Recently, several experimental methodologies were successfully employed to avoid poisonings by sodium monofluoroacetate containing plants. These methodologies include the induction of food avertion using lithium chloride, the ministration of repeatedly non-toxic doses of leaves to induce resistance, the use of acetamide to prevent poisonings and the intraruminal inoculation of sodium monofluoroacetate degrading bacteria. © 2018 Colegio Brasileiro de Patologia Animal.

RESUMO.
Esta revisão atualiza informações sobre plantas cardiotóxicas que afetam os ruminantes no Brasil. Atualmente, sabe-se que existem pelo menos 131 plantas tóxicas pertencentes a 79 gêneros. Vinte e cinco espécies afetam o funcionamento do coração. As plantas que contêm monofluoroacetato de sódio (Palicourea spp., Psychotria hoffmannseggiana, Amorimia spp., Niedenzuella spp., Tanaecium bilabiatum e Fridericia elegans) causam numerosos surtos de intoxicação, principalmente em bovinos, mas búfalos, ovinos e caprinos são ocasionalmente afetados. A intoxicação por Palicourea marcgravii continua a ser a mais importante devido à ampla distribuição desta planta no Brasil. Novas espécies do gênero Palicourea contendo monofluoracetato de sódio, como Palicourea amapaensis, Palicourea longiflora, Palicourea barraensis, Palicourea macarthurorum, Palicourea nigricans, Palicourea vacillans e Palicourea aff. juruana foram descritas na região amazônica. Na região nordeste, a planta tóxica mais importante para bovinos é Amorimia septentrionalis. No Centro-Oeste, surtos de intoxicação por Niedenzuella stannea foram relatados em bovinos na região do Araguaia e a doença precisa ser melhor investigada quanto à sua ocorrência e importância. Tetrapterys multiglandulosa e Tetrapterys acutifolia, duas plantas que causam fibrose cardíaca, também contêm monofluoracetato de sódio e foram reclassificadas para o gênero Niedenzuella. Essas duas espécies e Ateleia glazioveana, outra planta que causa fibrose cardíaca, continuam sendo importantes no Sul e Sudeste do Brasil. Outras espécies menos importantes e que ocasionamente provocam surtos acidentais de intoxicação são as plantas que contém glicosídeos cardiotóxicos, tais como Nerium oleander e Kalanchoe blossfeldiana. Recentemente, várias metodologias experimentais foram empregadas para evitar intoxicações por plantas que contêm monofluoroacetato de sódio. Estas metodologias incluem a indução de aversão condicionada utilizando cloreto de lítio, a utilização de doses repetidas não tóxicas de folhas para induzir resistência, o uso de acetamida para prevenir as intoxicações e a inoculação intraruminal de bactérias degradantes de monofluoroacetato de sódio.

Abstract:
Bovine viral diarrhea virus (BVDV) is a major pathogen worldwide, causing signifcant economic losses to the livestock sector. In Uruguay, BVDV seroprevalence at the farm level is >80%. In this work, 2546 serum, blood or tissue samples collected from animals suspected of being afected by BVD between 2015 and 2017 were analyzed by reverse transcription PCR and sequencing. Analysis of the BVDV genomic regions 5?UTR/Npro, Npro and E2 revealed that BVDV-1a, 1i and 2b circulate
in the country, with BVDV-1a being the most prevalent subtype. Population dynamics studies revealed that BVDV-1a has been circulating in our herds since ~1990. This subtype began to spread and evolve, accumulating point mutations at a rate of 3.48 × 10?3 substitutions/site/year, acquiring specifc genetic characteristics that gave rise to two local genetic lineages of BVDV-1a. These lineages are divergent from those circulating worldwide, as well as the vaccine strain currently used
in Uruguay. The most notable diferences between feld and vaccine strains were found in the E2 glycoprotein, suggesting that the amino acid substitutions could result in failure of cross-protection/neutralization after vaccination. This is the frst study that compares Uruguayan BVDV feld and vaccine strains with other BVDV strains from throughout the world. The results obtained in this study will be very useful for developing a suitable immunization program for BVDV in Uruguay by
identifying local feld strains as candidates for vaccine development. MenosAbstract:
