Resumo: | ABSTRACT. Galvão G. da S., Flausino W. & Lopes C.W.G. [Frequency of antibodies anti-Neospora caninum in water buffaloes (Bubalus bubalis) in the State of Rio de Janeiro, Brazil]. Anticorpos anti-Neospora caninum em búfalos (Bubalus bubalis) no estado do Rio de Janeiro, Brasil. Revista Brasileira de Medicina Veterinária, 35 (Supl.2):13-16, 2013. Curso de Pós-Graduação em Ciências Veterinárias, Instituto de Veterinária, Universidade Federal Rural do Rio de Janeiro, Campus Seropédica, BR 465 Km 7, Seropédica, 23897-970, RJ, Brasil.E-mail: galvaovet@gmail.com This study aimed to determine the presence of antibodies against Neospora caninum and the distribution among the different age groups in water buffaloes herds located in the mesoregions that comprise the state of Rio de Janeiro, Brazil. The frequency of seropositive animals in herds was 29.76% (86/ 289). Antibodies against N. caninum was detected in 14 (87.5%) of 16 properties, with positive ranging from 3.57 to 100%. Of the 298 animals examined, only 270 water buffaloes could be categorized into four age groups: ≤ 2 years, 2 to ≤ 4 years, 5-6 years and> 6 years, were subjected to indirect fluorescence antibody test (IFAT), with a cutoff of 1:200, thus presenting 27.41 % of seropositive animals (74/ 270). The Fisher exact test was used with a significance level of 5%. In the present study we observed differences in seropositivity according to different ages (p = 0.027), and animals aged more than five years had 2.62 further chances of exposure.The results show the exposure of water buffaloes to N. caninum in the regions studied, and should include the parasite in the differential diagnosis of possible cases of water buffaloes abortion, and revel the need to adopt health measures for the control of infection in water buffaloes herds. |

A frequência de animais soropositivos nos rebanhos foi de 29,76% (86/289). Anticorpos contra-N. caninum foram detectados em 14 (87,5%) das 16 propriedades, com positividade variando de 3,57 a 100%. Dos 298 animais analisados, apenas270 bubalinos puderam ser categorizados em quatro estratos: ≤ 2 anos ,2 a ≤4 anos, 5-6 anos e >6 anos e foram submetidas à técnica de reação de imunofluorescência indireta com ponto de corte de 1:200, apresentando assim 27,41% de animais sororreagentes (74/270).O teste exato de Fisher foi utilizado com nível de significância de 5%. No presente estudo observou-se diferenças em relação a soropositividade em função das diferentes idades (p=0,027), e animais com idade superior a cinco anos apresentaram2,62 mais chances de exposição ao agente. Os resultados obtidos evidenciam a exposição de bubalinos aN. caninum nas mesorregiões estudadas, devendo-se incluir o parasito no diagnóstico diferencial nos possíveis casos de abortamento bubalino, bem como evidencia a necessidade de adoção de medidas sanitárias para o controle da infecção nos rebanhos avaliados.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2014-03-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdfhttps://rbmv.org/BJVM/article/view/659Brazilian Journal of Veterinary Medicine; Vol. 35 No. Supl.2 (2013); 13-16Revista Brasileira de Medicina Veterinária; v. 35 n.
