Serological survey of porcine circovirus 2 antibodies in Northeastern Brazil by immunoperoxidase monolayer assay

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 No...

Zusammenfassung: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.
