EnglishThe presence of anti-Neospora caninum antibodies in beef cattle slaughtered in the northern region of the state of Parana, Brazil, was evaluated. A total of 401 blood samples were collected; 281 samples from the municipality of Rolândia and 120 from the municipality of Borrazopolis, between April 2015 and November 2016. Of the total samples, 289 were from females and 112 from males, aged one and a half to eight years. Indirect fluorescent antibody test (IFAT) was performed, using a cut-off of 1:100. Variables were tabulated for statistical analyses (Fisher’s exact test and chi-square tests, p≤0.05). The analysis showed that of the 401 samples, 37 were positive for N. caninum, indicating a prevalence of 9.2 %, and observed titers were 1:100 (16), 1:200 (14), and 1:400 (7). The variables sex, age, and location did not differ statistically (p>0.05). Our results showed a sero-occurrence of N. caninum in cattle slaughtered in the northern region of the state of Parana. Key words: Neosporosis; seroprevalence; IFAT; cattle; Parana state portuguesA presenca de anticorpos anti-Neospora caninum em bovinos de corte, abatidos na regiao norte do estado do Parana, Brasil, foi avaliada. Foram coletadas 401 amostras de sangue, sendo 281 amostras no municipio de Rolândia e 120 no municipio de Borrazopolis, entre os meses de abril de 2015 e novembro de 2016. Do total de amostras, 289 eram de femeas e 112 amostras de machos, na faixa etaria de um ano e meio ate oito anos de idade. Foi realizada a reacao da imunofluorescencia indireta (RIFI) utilizando ponte de corte de 1:100. Em seguida, foram tabulados as variaveis para analise estatistica (testes exato de Fisher e do qui-quadrado, p≤0,05). A analise mostrou que das 401 amostras, 37 foram positivas para N. caninum, indicando uma prevalencia de 9,2 % e os titulos observados foram 1:100 (16), 1:200 (14) e 1:400 (7). As variaveis sexo, idade e local nao diferiram estatisticamente (p>0,05). Nossos resultados demonstram uma soro-ocorrencia de N. caninum em bovinos abatidos na regiao norte do Parana.
