Surto de encefalomielite equina Leste na Ilha de Marajó, Pará

Nine cases of equine encephalomyelitis on Marajó Island, state of Pará, Brazil, were studied. The affected horses had difficulty to stand, walked in circles, with marked depression, closed eyelids, tongue paralysis, muscle tremors, bruxism, anorexia and dehydration. Some had their ear and eyelid ref...

The affected horses had difficulty to stand, walked in circles, with marked depression, closed eyelids, tongue paralysis, muscle tremors, bruxism, anorexia and dehydration. Some had their ear and eyelid reflexes diminished, decreased tongue tone and tachycardia; laid down frequently they kept their head on the chest. Often they were seen resting their head on tree trunks or fences. At necropsy, hemorrhages of the meninges and spinal cord, and in some animals also adhesion of the meninges were found. Histologically there was diffuse encephalitis affecting mainly the gray matter, with meningitis and choroiditis. Presence of perivascular cuffs consisting of mononuclear inflammatory cells was observed. From two horses the Eastern equine encephalitis virus was identified by semi-nested reverse transcription polymerase chain reaction (semi-nested RT-PCR). Nove casos de encefalomielite equina foram estudados na Ilha de Marajó, estado do Pará, Brasil. Os equinos apresentavam dificuldade em se manter em estação, andavam em círculo, tinham acentuada depressão, pálpebras cerradas, paralisia da língua, tremores musculares, bruxismo, anorexia e desidratação. Alguns apresentavam diminuição dos reflexos auricular, palpebral, de ameaça, diminuição do tônus da língua e taquicardia. Posição de auto-auscultação foi observada com frequência. Os animais muitas vezes eram encontrados apoiados em troncos e cercas para se manterem em estação. À necropsia verificou-se hemorragia das leptomeninges e da medula, alguns apresentaram ainda aderência das leptomeninges. À histopatologia verificou-se encefalite difusa que afetava principalmente a substância cinzenta, com meningite e coroidite. Foi observada perivasculite mononuclear. Em dois equinos identificou-se o vírus da encefalomielite equina Leste pela reação de Semi-Nested transcrição reversa de polimerase em cadeia (Semi-Nested RT-PCR). 2014-08-22T14:38:24Z 2014-08-22T14:38:24Z 2013-04 Artigo de Periódico CAMPOS, Karinny F. et al.
