title: Antibodies against 12 serotypes of Actinobacillus pleuropneumoniae in finnish slaughter sows.
abstract: To determine the prevalence of A. pleuropneumoniae serotypes in Finnish pig populations, 692 blood samples of sows were randomly collected from Finnish slaughterhouses. These were assayed with a direct ELISA for 12 Actinobacillus pleuropneumoniae serotypes. The specificity of the ELISA was tested using rabbit antisera against these serotypes. Cross-reactions were detected between serotypes 6 and 8 and between serotypes 1, 9 and 11, and serotype 5 antiserum reacted with serotype 6 antigen, but the other serotypes did not cross-react. When assaying the blood samples serotype 3 and 2 antibodies were found in 51% and 26% of samples, respectively. Other serotypes were found only in smaller numbers. Most of the samples, 61%, had antibodies towards some serotype of A. pleuropneumoniae. Antibodies towards serotypes 2 and 3 were found in pigs throughout Finland.
