Resumo: | Direct and indirect immunofluorescence techniques and a culture method were compared for detection of Mycoplasma hyopneumoniae in lungs of experimentally infected swine. Pneumonic lungs were obtained from SPF pigs that had been exposed by contact 6 to 7 weeks previously to other SPF pigs which had been inoculated with the organism. A good association was found between isolation of M. hyopneumoniae, positive immunofluorescence test results and presence of macroscopic or microscopic lesions typical of mycoplasmal pneumonia of swine. Direct and indirect immunofluorescence tests were equally efficient for detection of M. hyopneumoniae in sections of lung. An azo dye counterstain reduced nonspecific fluorescence and provided a good color contrast without reducing sensitivity of the indirect immunofluorescence test. |

Estes pulmões foram obtidos de animais SPF após seis a sete semanas de início de um período de contato com outros animais SPF inoculados experimentalmente com o agente. Uma boa associação foi encontrada entre o isolamento de M. hyopneumoniae, resultados positivos em ambas as técnicas de imunofluorescência e lesões macroscópicas e microscópicas típicas de pneumonia micoplásmica dos suínos. Tanto a imunofluorescência direta como indireta foram igualmente eficientes na detecção de M. hyopneumoniae em secções de pulmão. Uma coloração azo de fundo reduziu a fluorescência inespecífica e possibilitou um bom contraste de cor sem reduzir a sensibilidade do método indireto de imunofluorescência.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPiffer, Itamar AntônioRoss, Richard Francis2014-10-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15894Pesquisa Agropecuaria Brasileira; v.20, n.8, ago. 1985; 877-882Pesquisa Agropecuária Brasileira; v.20, n.8, ago. 1985; 877-8821678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/15894/9982info:eu-repo/semantics/openAccess2014-04-17T11:58:54Zoai:ojs.seer.sct.embrapa.br:article/15894Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T11:58:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
