Resumo: This study aimed to assess the fluctuations of antibody serum titers for Toxoplasma gondii and Neospora caninum in naturally infected crossbred cows during gestation and to investigate transplacental transmission of T. gondii; 51 cows were monitored during pregnancy by monthly serologic testing by indirect fluorescent antibody test. 33 cows were seronegative for both N. caninum and T. gondii, 10 were seropositive only for N. caninum, 5 were seropositive only for T. gondii, and 3 were seropositive for both N. caninum and T. gondii. In both protozoan infections, great variation in antibody levels in pregnant cows was observed, and there was significant increase (p<0.05) in the comparison between the averages of serological titration per trimester. There was a significant correlation (p<0.05) between month and probability of seropositivity for T. gondii. We conclude that pregnancy influences antibody titers of crossbred cows naturally infected with N. caninum and/or T. gondii, and that serologic testing for T. gondii in pregnant cows from the sixth month of gestation onward may decrease the number of false negative results.

Em ambas as infecções, observou-se grande variação nos níveis de anticorpos em vacas gestantes, e houve um aumento significativo (p<0.05) na comparação entre as medias da titulação sorológica por trimestre. Houve correlação significativa (p<0,05) entre os meses e a probabilidade de soropositividade para T. gondii. Conclui-se que a gestação influencia os títulos de anticorpos de vacas mestiças naturalmente infectadas por N. caninum e/ou T. gondii e que testes sorológicos para T. gondii em vacas gestantes a partir do sexto mês podem diminuir o número de resultados falsos negativos.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2023-12-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdftext/xmlhttps://bjvm.org.br/BJVM/article/view/131710.29374/2527-2179.bjvm003023Brazilian Journal of Veterinary Medicine; Vol. 45 (2023); e003023Revista Brasileira de Medicina Veterinária; v. 45 (2023); e0030232527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVenghttps://bjvm.org.br/BJVM/article/view/1317/1371https://bjvm.org.br/BJVM/article/view/1317/1380Copyright (c) 2023 Uillians Volkart de Oliveira, Vanessa Carvalho Sampaio de Magalhães, Sônia Carmen Lopo Costa, Ivan Bezerra Allaman, Alexandre Dias Munhozhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessde Oliveira, Uillians Volkartde Magalhães, Vanessa Carvalho SampaioCosta, Sônia Carmen LopoAllaman, Ivan BezerraMunhoz, Alexandre Dias2024-01-08T13:58:31Zoai:ojs.rbmv.org:article/1317Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2024-01-08T13:58:31Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false
