Resumo: | Duroc, Hampshire, Landrace and Largo White sows were immunized between the 70th and 90th days of one, two or three successive gestations with an inactivated oil-emulsion vaccine against Aujeszky's disease. The levels of neutralizing antibodies in the sows were evaluated at two and 16 weeks after farrowing. Similarly, the levels of neutralizing antibodies in their piglets were determined at two, four, six, eight, ten, twelve, fourteen and 16 weeks of age. At two and 16 weeks after farrowing, respectively, only 18.8% and 44.4% of the sows vaccinated once had neutralizing antibodies while one hundred percent of sows vaccinated twice and tested two and 16 weeks after farrowing were positive. On the other hand, 78.6% and 75% of the sows vaccinated three times posessed antibodies, respectively, two and 16 weeks post farrowing. Neutralizing antibodies of maternal origin were demonstrable in the piglets from the second week of life onwards. Those antibodies were present only in the piglets of sows with antibodies. In piglets of sows vaccinated only once, maternally-derived antibodies persisted up to the 10th or 12th week of life, while in piglets of sows vaccinated two or three times, those antibodies persisted a maximum of fourteen weeks. |

Os níveis de anticorpos neutralizantes, nas porcas, foram avaliados às duas e 16 semanas apos o parto. Similarmente, os níveis de anticorpos neutralizantes foram determinados nos leitões destas porcas às duas, quatro, seis, oito, dez, doze, quatorze e 16 semanas de idade. A duas e 16 semanas apos o parto, respectivamente, apenas 18,8% e 44,4% das porcas vacinadas uma vez possuíam anticorpos neutralizantes, enquanto que cem por cento das porcas vacinadas duas vezes e testadas a duas e 16 semanas eram positivas. Por outro lado, 78,6% e 75% das porcas vacinadas três vezes possuíam anticorpos, respectivamente a duas e 16 semanas após o parto. Anticorpos neutralizantes de origem materna foram detectados nos leitões a partir da segunda semana de idade. Esses anticorpos estavam presentes apenas nos leitões de porcas com anticorpos. Em leitões de porcas vacinadas uma vez, os anticorpos de origem materna persistiram até a décima ou a 12ª semana de idade, enquanto que, em leitões de porcas vacinadas duas ou três vezes, esses anticorpos persistiram até um máximo de quatorze semanas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRomero, Carlos H.Flores, Robis S.2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14700Pesquisa Agropecuaria Brasileira; v.22, n.11/12, nov./dez. 1987; 1231-1238Pesquisa Agropecuária Brasileira; v.22, n.11/12, nov./dez. 1987; 1231-12381678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14700/8386info:eu-repo/semantics/openAccess2014-10-15T17:25:20Zoai:ojs.seer.sct.embrapa.br:article/14700Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-15T17:25:20Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
