Abstract
|
|
|
|
Proliferative enteropathy caused by Lawsonia intracellularis is one of the most common enteric diseases in pigs. The objective of this study was to determine the prevalence of serum antibodies against L. intracellularis in the general swine population of Korea from 2005 to 2008. In total, 8,008 swine serum samples obtained from 1,001 herds were tested. The samples were analyzed with an immunoperoxidase monolayer assay to detect anti-L. intracellularis antibodies. The overall 4-year average true prevalence was 40.0% (CI: 39.4 - 40.6%) at the individual animal level and 71.9% (CI: 70.3-73.4%) at the herd level.
