Abstract
Summary: A direct ELISA with phenol‐extracted antigen for Actinobacillus pleuropneumoniae serotype 2 was developed. The test was specific when tested with rabbit antisera prepared against different A. pleuropneumoniae serotypes. It had better‐than‐moderate repeatability and it made a clear distinction between positive and negative samples.A total of 5477 colostrum samples from breeding sows from herds participating in the Finnish Pig‐health Scheme were tested using the ELISA test. A total of 1307 positive samples were found in 129 out of 154 herds, thus indicating that most of the disease‐control herds in Finland are infected with A. pleuropneumoniae serotype 2. These infections were almost entirely subclinical.Keywords
