Abstract

Sera of pigs with clinically normal and infectious conditions were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE) to demonstrate the specific changes in protein profile. In the sera from pigs with infection, haptoglobin with a 40KDa protein was found to be increased as compared to that of sera from normal pigs. As a rapid detection method for monitoring infections at large-scale farms, one of acute phase protein, haptoglobin, was selected to compare the concentrations between infectious and non-infectious conditions. Haptoglobin concentrations were low in pigs with clinically normal conditions but significantly increased in pigs with Aujesky's disease, hog cholera and parvo-virus infection. The studies provide that haptoglobin can be used as an indicator to monitor infections early at farm level.
