Resumo: Porcine circovirus 2 (PCV2) specific antibodies were evaluated in pigs at 15 to 25 weeks of age by immunoperoxidase monolayer assay. Serum samples (n = 575) were obtained from 16 commercial farms located in six states of northeastern Brazil, including two in Ceará (n = 85), three in Rio Grande do Norte (n = 92), two in Paraíba (n = 49), three in Pernambuco (n = 107), two in Alagoas (n = 39), and four in Bahia (n = 203). Out of the 575 evaluated sera, 470 (81.74%) were reagents with antibody titers ranging from 20 to 5,120. All farms presented reactive animals. There was a statistically significant difference in reactivity proportions between the states of Bahia and Ceará (p < 0.05) and between Bahia and Rio Grande do Norte (p < 0.05). This study provides the first serological investigation for PCV2 in pigs from commercial farms in Northeastern Brazil.

As amostras de soros (n = 575) foram procedentes de 16 granjas comerciais localizadas em seis Estados da região Nordeste do Brasil, incluindo duas no Ceará (n = 85), três no Rio Grande do Norte (n = 92), duas na Paraíba (n=49), três em Pernambuco (n = 107), duas em Alagoas (n = 39) e quatro na Bahia (n = 203). Dos 575 soros avaliados, 470 (81,74%) foram reagentes com títulos de anticorpos que variaram de 20 até 5.120. Todas as granjas avaliadas apresentaram animais reagentes. Houve diferença estatística significante nas proporções de sororeatividade entre os Estados da Bahia e Ceará (p < 0,05) e entre os Estados Bahia e Rio Grande do Norte (p < 0,05). Este estudo mostra a primeira investigação sorológica para PCV2 em suínos de granjas comerciais da região Nordeste do Brasil.UEL2020-01-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3532010.5433/1679-0359.2020v41n1p345Semina: Ciências Agrárias; Vol. 41 No. 1 (2020); 345-350Semina: Ciências Agrárias; v. 41 n. 1 (2020); 345-3501679-03591676-546Xreponame:Semina.
