Salmonella choleraesuis in Swine
Publish Date: June 3, 2006
Salmonellosis, the disease that may result from Salmonella infection, continues to have a significant economic impact on the national swineherd. Between 1975 and 1995 , S. choleraesuis was one of the most common organisms isolated from cases of swine pneumonia and septicemia. It also was the most prevalent serotype (>90% of isolates) of all Salmonella isolated from diseased swine. In 1991, it was estimated that the disease caused by S. choleraesuis cost pork producers in the United States more than $100 million annually due to death losses, medication costs, and poor production efficiency of survivors. Since the mid-1990’s, the prevalence of S. choleraesuis associated disease has moderated. Currently, serotypes of Salmonella other than S. choleraesuis have increased in frequency and presently account for over 50% of the serotypes isolated from diseased swine.
