Resumo: The objective of this study was to establish the frequency of infection and to analysis risk factors to Neospora caninum in calves and heifers from 18 dairy herds of Lavras, Minas Gerais State. Five hundred and thirty and four samples were screened by indirect immunofluorescence antibody test (IFAT) using cut off dilution of 1:200. The dairy herds were classified in two groups: group A) herds produced more than 1,000 lid of milk/day and group B) herds produced less than 1,000 lid of milk/day. The herd prevalence was 100% (18/18). The overall frequency of N. caninum infection was 46.25% (247/534) such as 43.66% (93/213) and 47.97% (154/321) in group A and B, respectivelly. There was no statistically significant difference between the groups (p>0.05). There was no significant association between risk factor and serology for N. caninum (p>0.05). The results indicate that the infection for N. caninum appears to be widespread between calves and heifers of dairy herds in microregion of the Lavras, south of Minas Gerais State.KEY WORDS: Antibodies, indirect immunofluorescence antibody test, Neospora caninum, cattle.

Para isso, coletaram-se 534 amostras de soros de bezerras (maiores de três meses idade) e novilhas até 24 meses de idade, e dividiram-se em dois grupos de acordo com a produção de leite da fazenda: grupo A (<1.000 litros de leite/dia) e grupo B (>1.000 litros de leite/dia). A sorologia foi realizada por meio da reação de imunofluorescência indireta (RIFI) e como ponto de corte o título de 1:200. Realizaram-se as análises descritivas de todas as variáveis deste estudo no programa SPSS 12.0 for Windows. Testou-se a associação entre níveis de positividade para N. caninum nos rebanhos com as variáveis coletadas por meio de questionário, mediante o Teste Exato de Fisher e, para testar a diferença de médias, utilizou-se o Teste T de Student. A frequência nos rebanhos foi de 100% (18/18). A frequência média global de animais infectados por N. caninum foi de 46,25% (247/534) e 43,66% (93/213), para fazendas do grupo A, e de 47,97% (154/321) para o grupo B. Não se registrou diferença significativa (p>0,05) entre os dois grupos, nem entre os fatores de risco e a soropositividade para N. caninum. A infecção por N. caninum está amplamente distribuída entre bezerras e novilhas de rebanhos leiteiros da microrregião de Lavras, sul de Minas Gerais.PALAVRAS-CHAVES: Anticorpos, Neospora caninum, imunofluorescência indireta, bovinos.PALAVRAS-CHAVE: anticorpos, Neospora caninum, imunofluorescência indireta, bovinos.Universidade Federal de Goiás2009-04-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisa Científicaapplication/pdfhttps://revistas.ufg.br/vet/article/view/303210.5216/cab.v10i1.3032Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 10 No. 1 (2009); 271-280Ciência Animal Brasileira / Brazilian Animal Science; v. 10 n. 1 (2009); 271-2801809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/3032/4594Santos, Raquel Ribeiro DiasGuimares, Antonio MarcosRocha, Christiane Maria B.
