Serum samples were collected from 923 goats of both sexes, over 3 months of age, from 17 dairy farms located in different municipalities of São Paulo State, Brazil. Infections by T. gondii, N. caninum and CAEV were evaluated by indirect methods of diagnosis based on indirect fluorescence antibody test (IFAT), Neospora agglutination test (NAT), and agar gel immunodiffusion (AGID), respectively. A survey was conducted on the farms to obtain information about reproduction dates (abortions, stillbirths and births of weak and premature kids) and zoosanitary management. Antibodies against CAEV, T. gondii and N. caninum was found in 37.81%, 23.62% and 17.23% respectively. There was no significant association between the presence of anti-CAEV antibodies and CAEV/T. gondii or CAEV/N. caninum co-infection, suggesting that CAEV does not predispose goats to infection by these agents. However, when CAEV/T. gondii (p<0.01) or CAEV/N. caninum (p<0.001) co-infection was present, the occurrence of reproductive failures was significantly higher what could indicate that CAEV-induced immunosuppression may predispose goats to develop the clinical symptoms of toxoplasmosis and neosporosis increasing the risks of the reproductive failures.Department of Veterinary Hygiene and Public Health School of Veterinary Medicine and Animal Science São Paulo State University, Botucatu-SPDepartment of Biostatistics Institute of Biosciences São Paulo State University, Botucatu-SPDepartment of Preventive Veterinary Medicine and Animal Health Faculty of Veterinary Medicine and Animal Science, São Paulo-SPDepartment of Veterinary Hygiene and Public Health School of Veterinary Medicine and Animal Science São Paulo State University, Botucatu-SPDepartment of Biostatistics Institute of Biosciences São Paulo State University, Botucatu-SPUniversidade Estadual Paulista (Unesp)Faculty of Veterinary Medicine and Animal Science2014-05-27T11:27:24Z2014-05-27T11:27:24Z2012-12-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article67-72application/pdfhttp://www.revistas.usp.br/bjvras/article/view/40261Brazilian Journal of Veterinary Research and Animal Science, v. 49, n. 1, p. 67-72, 2012.1413-95961678-4456http://hdl.handle.net/11449/740112-s2.0-848725712952-s2.0-84872571295.pdf8727897080522289Scopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengporBrazilian Journal of Veterinary Research and Animal Science0,2250,225info:eu-repo/semantics/openAccessda Costa, Heni Falcão [UNESP]Stachissini, Anne Valéria Mendonça Stachissini [UNESP]Langoni, Hélio [UNESP]Padovani, Carlos Roberto [UNESP]Gennari, Solange MariaModolo, José Rafael [UNESP]2025-10-23T08:19:31Zoai:repositorio.unesp.br:11449/74011Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestrepositoriounesp@unesp.bropendoar:29462025-10-23T08:19:31Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false |
