摘要
A mixed-antigen enzyme-linked immunosorbent assay (ELISA) containing serotype-specific polysaccharide antigens from serotypes 1, 5, and 7 of Actinobacillus pleuropneumoniae was developed. This ELISA was evaluated using sera from experimentally infected pigs. With a negative cutoff value of 0.250 (optical density at 405 nm), sensitivity and specificity were determined to be 96% and 99.5%, respectively. The ELISA was further evaluated using sera from commercial swine. Sows and suckling piglets were found to be the best age groups for detection of positive reactors to A. pleuropneumoniae. The mixed-antigen ELISA could be used in a herd health monitoring program for detection of A. pleuropneumoniae infections.
