RESUMO
A técnica de imunoperoxidase em monocamada de células (IPMC) para demonstração de anticorpos contra o circovírus suíno tipo 2 (CVS2) foi empregada para a investigação sorológica em oito granjas de suínos destinadas à produção comercial. Das 240 amostras de soros testadas, 229 (95,4%) foram reagentes com títulos que variaram de 20 até 10.240. Títulos de anticorpos foram detectados nas faixas etárias de duas a três semanas até animais acima de 24 semanas e encontrados em granjas com e sem a síndrome multissistêmica do definhamento (SMD). A média dos títulos de anticorpos revelou diferenças estatísticas (P<0,05) nas faixas etárias de 11 a 13 e 14 a 22 semanas nos animais oriundos de granjas com e sem a SMD. Os resultados refletem a importância de conhecer o perfil sorológico do rebanho e assegurar a implantação de um efetivo cronograma de vacinação contra o CVS2.
ABSTRACT
The immunoperoxidase in monolayer cells (IPMC) technique for the demonstration of antibodies against type 2 porcine circovirus (PCV2) was used for the serological investigation in eight industrial swine farms. Out of the 240 tested sera, 229 (95,4%) were reactive with titers which varied from 20 up to 10.240. Titers of antibodies were detected in pigs from two to three weeks of age up to above 24 weeks of age, and were observed in farms with and without clinical signs indicative of the post-weaning multisystemic wasting syndrome (PMWS). Analysing the mean titers, statistical differences (P<0.05) were evidentiated in two age intervals, of 11 to 13 and 14 to 22 weeks of age. The results indicate the importance of determining the serological profiles of commercial swine herds, in order to enable the implantation of effective hygiene and vaccination protocols for PCV2 prevention.
