No. of bitstreams: 1 PGCA17MA224.pdf: 1064233 bytes, checksum: 031ba44fb55de3f4ff7bd6dc82539958 (MD5) Previous issue date: 2017-02-24 / FUMDES / Listeriosis is a disease caused by bacteria of the genus Listeria spp, especially Listeria monocytogenes, the nervous form is the most important and frequent manifestation, characterized by a fatal meningoencephalitis, which mainly affects ruminants. We describe the epidemiological data, clinical signs and lesions of 27 outbreaks of listeriosis nerve in sheep and two in goats, diagnosed in the Laboratory of Animal Pathology (LAPA/CAV) between january 2007 and november 2015, in Santa Catarina. During this period, the disease occurred in the regions of Planalto Serrano, Alto Vale do Itajaí, North, Midwest, West and Florianópolis region. The animals affected were evaluated clinically and after worsening the clinical condition, were euthanized and necropsied with subsequent evaluation of macroscopic lesions, collection of viscera samples for histopathological examination and submission of refrigerated central nervous system samples for bacterial isolation. Silage samples from the properties where the outbreaks occurred were also sent with the same purpose. Sheep and goats presented clinical neurological signs such as incoordination, tournament, torticollis, salivation, protrusion and flaccidity of the tongue, unilateral palpebral, atrial and labial ptosis, as well as congestion of ocular mucosa and hyperthermia. The clinical condition varied from 5 to 10 days. All animals died even treated with antibiotics. At necropsy, small areas of dark and/or yellowish color were observed in the midbrain and hyperemia of the piamater. Histological lesions were characterized by perivascular mononuclear infiltrate and multifocal neutrophils in the central nervous system. The bacterial isolation was positive for the species Listeria monocytogenes, Listeria innocua, Listeria welshimeri and Listeria grayi / Listeriose é uma enfermidade provocada por bactérias do gênero Listeria spp, especialmente Listeria monocytogenes, sendo a forma nervosa a manifestação mais importante e frequente, caracterizada por um quadro de meningoencefalite fatal, que acomete principalmente ruminantes. Descrevem-se os dados epidemiológicos, sinais clínicos e lesões de 27 surtos de listeriose nervosa em ovinos e dois em caprinos, diagnosticados no Laboratório de Patologia Animal (LAPA/CAV) no período entre janeiro de 2007 a novembro de 2015, no estado de Santa Catarina. Durante este período, a doença ocorreu nas regiões do Planalto Serrano, Alto Vale do Itajaí, Norte, Oeste, Meio Oeste e Grande Florianópolis. Os animais acometidos foram avaliados clinicamente e após agravamento do quadro clínico, foram eutanasiados e necropsiados com posterior avaliação das lesões macroscópicas, coleta de amostras de vísceras para processamento histopatológico e envio de amostras refrigeradas de sistema nervoso central para isolamento bacteriano. Amostras de silagem provenientes das propriedades onde ocorreram os surtos também foram enviadas com a mesma finalidade. Os ovinos e caprinos apresentaram sinais clínicos neurológicos como incoordenação, torneio, torcicolo, salivação, protrusão e flacidez de língua, ptose palpebral, auricular e labial unilaterais, além de congestão de mucosa ocular e hipertermia. O quadro clínico variou de 5 a 10 dias. Todos os animais morreram mesmo tratados com antibióticos. Na necropsia foram observadas pequenas áreas de coloração escura e/ou amareladas no mesencéfalo e hiperemia da piamáter. As lesões histológicas foram caracterizadas por infiltrado mononuclear perivascular e de neutrófilos, multifocal, no sistema nervoso central. O isolamento bacteriano foi positivo para as espécies Listeria monocytogenes, Listeria innocua, Listeria welshimeri e Listeria grayi
