Resumo: Neosporosis is one of the major causes of reproductive failure in bovine around the world. The periodof gestation, in which the infection or the recrudescence of bradzoites forms occurs and reflects inthe antibodies levels, is one of the factors that define pregnancy future. Therefore, this study aimedto determine the serological profile during pregnancy of naturally infected females. To do that,serological samples of 25 Holstain Friesian cows were collected from artificial insemination dayuntil parturition, in monthly intervals. These samples were tested by indirect immunofluorescencefor IgG anti-Neospora caninum. Of the 25 animals, only 13 were used in the analysis, becausethey were seropositive since the beginning or seroconverted during pregnancy. The results showeda gradual increase in antibody levels along pregnancy, more visible at the end of the period. Weobserved a significant difference in antibodies title between initial and final periods of pregnancy, which suggests the reactivation of bradzoite forms present in tissues during pregnancy. These resultsreinforce the knowledge of antibodies fluctuation along pregnancy, affected by N. caninum reinfectionor reactivation. This serological knowledge is important to Neosporosis pathogeny, epidemiology anddiagnostic.Keywords: bovine; indirect immunofluorescence; neosporosis; pregnancy; serology.

O estágio dagestação em que ocorre a infecção ou o recrudescimento das formas bradizoítas, que se reflete nonível de anticorpos, é um dos fatores que define o futuro da gestação. Portanto, este trabalho visa atraçar um esboço do perfil sorológico de fêmeas naturalmente infectadas durante a gestação. Para isso,amostras séricas de 25 vacas da raça holandesa foram coletadas desde o dia da inseminação artificialaté a véspera do parto, em intervalos mensais. Essas amostras foram testadas por imunofluorescênciaindireta em busca de IgG. Dos 25 animais, somente 13 foram utilizados na análise, por seremsoropositivos desde o início ou por se soroconverteram durante a gestação. Observou-se um aumentogradual dos níveis de anticorpos ao longo da gestação, mais evidente na metade final do período.Observou-se também diferença significativa nos títulos de anticorpos entre os períodos iniciais efinais da gestação, sugerindo a reativação de formas bradizoítas. Tais resultados reforçam a ideia daflutuação nos níveis de anticorpos ao longo da gestação, influenciado pela reativação de N. caninum.O conhecimento dessa dinâmica é importante para a patogenia e epidemiologia da infecção bemcomo para o diagnóstico.Palavras-chave: bovinos; gestação; imunofluorescência indireta; Neosporose; sorologia.Universidade Federal de Goiás2015-10-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/2812710.1590/cab.v16i4.28127Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 16 No. 4 (2015); 553-559Ciência Animal Brasileira / Brazilian Animal Science; v. 16 n. 4 (2015); 553-5591809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/28127/19460https://revistas.ufg.br/vet/article/view/28127/19461Antonello, Ana MariaCamillo, GiovanaWeber, AugustoBraunig, PatríciaSangioni, Luis AntonioVogel, Fernanda Silveira Floresinfo:eu-repo/semantics/openAccess2015-11-10T17:44:06Zoai:ojs.revistas.ufg.br:article/28127Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:04.852941Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
