ABSTRACT.
Amorimia septentrionalis is an important sodium monofluoroacetate (MFA) containing plant that causes sudden death in ruminants in northeastern Brazil. MFA degrading bacteria are being used in the prevention against poisoning by this plant. The aim of this study was to evaluate if goats which had per os received MFA degrading bacteria remained resistant when exposed to natural poisoning by A. septentrionalis. Eighteen goats were randomly distributed into three groups: the goats of Group 1 previously received, during 40 days, a solution containing the bacteria Ralstonia sp. and Burkholderia sp., those goats in the Group 2 received the bacteria Paenibacillus sp. and Cupriavidus sp. and goats from Group 3 did not receive any bacteria. After the administration period, during 60 days, the animals of all groups were released to graze on a one hectare paddock, with significant amount of A. septentrionalis. They were observed daily for the spontaneous consumption of A. septentrionalis leaves and the occurrence of clinical signs of poisoning or sudden death. Goats from all groups consumed significant amounts of A. septentrionalis during the experimental period. Goats that did not receive MFA-degrading bacteria (Group 3) became sick and died from the 25th to the 27th day of the experiment, whereas the goats of the groups that received MFA-degrading bacteria showed only clinical sings when A. septentrionalis regrowth after the 55th day of the experiment. The days elapsed from field observation to death of Group 3 goats (25.5±0.9 days) were significantly lower (p<0.05) than Group 1 (58.6±1.3 days) and Group 2 (57.8±1.5 days). Thus, it can be concluded that administration of MFA degrading bacteria increases the resistance to natural poisoning by A. septentrionalis.

RESUMO.
Amorimia septentrionalis que contém monofluoroacetato de sódio (MFA) é responsável pela ocorrência de mortes súbitas em ruminantes no nordeste do Brasil. Bactérias degradadoras desse composto estão sendo utilizadas na prevenção contra a intoxicação por essa planta. O objetivo deste estudo foi avaliar se caprinos que receberam, via oral, bactérias degradadoras de MFA permaneciam resistentes quando expostos a intoxicação natural por A. septentrionalis. Dezoito caprinos foram divididos em três grupos, os caprinos do Grupo 1 receberam anteriormente, durante 40 dias, uma solução contendo as bactérias Ralstonia sp. e Burkholderia sp., os do Grupo 2 receberam, também por 40 dias as bactérias Paenibacillus sp. e Cupriavidus sp. e os do Grupo 3 não receberam nenhuma bactéria. Após o período de administração, durante 60 dias, os animais de todos os grupos foram soltos para pastar em um piquete de um hectare, que apresentava uma quantidade significativa da planta. Diariamente eles foram observados quanto ao consumo espontâneo das folhas de A. septentrionalis e quanto à presença de sinais clínicos de intoxicação ou morte. Os caprinos de todos os grupos consumiram quantidades significantes da planta durante o período experimental. Os caprinos que não receberam as bactérias degradantes de MFA (Grupo 3) adoeceram e morreram entre o 25º e o 27º dia de experimento, enquanto que os que receberam as bactérias degradantes de MFA (Grupo 1 e 2) só apresentaram sinais clínicos no 55º dia de experimento, o que coincidiu com a rebrota da planta. Os dias transcorridos desde a observação a campo até a morte dos caprinos do Grupo 3 (25,5±0,9 dias) foram significativamente menores (p<0,05) que os do Grupo 1 (58,6±1,3 dias) e do Grupo 2 (57,8±1,5 dias). Com isso pode-se concluir que a administração de bactérias degradadoras de MFA aumenta à resistência a intoxicação natural por A. septentrionalis. MenosABSTRACT.

ABSTRACT.
The search for environmentally biocompatible and cost-effective methods to control filamentous fungi in agriculture is becoming increasingly urgent. In vitro antimicrobial activity of three synthetic peptides was investigated against some filamentous fungi with agricultural relevance. The peptides were an analog of Temporin called Temporizina, a fragment from Pleurocidin termed Plc-2, and a peptide identified from sesame seeds named Pses3. Antimicrobial activity of these peptides towards filamentous fungi has not been previously reported. Seven plant pathogenic or mycotoxigenic fungal species, isolated from plant tissues were assayed: Alternaria solani, Colletotrichum gloesporioides, Fulvia fulvum, Fusarium oxisporum, Aspergillus niger, A.
ochraceus and Penicillium digitatum. Values of Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration (MFC) were determined and compared with the commercially available fungicide Captan as a positive control. The peptides showing greatest inhibition were Pses3 and Plc-2 and C.
gloesporioides was the most sensitive of the evaluated fungi. The MIC values for Plc-2 and Pses3 peptides ranged from 0.64 µM to 10.25 µM. These values were much lower than those observed for Captan, suggesting the potential of these peptides as fungicides. In particular, Pses3 is a novel peptide derived from sesame seeds not reported in databases. |
