Interpretive Summary:

Technical Abstract: Salmonella choleraesuis and Salmonella typhimurium are the most common Salmonella serovars found in swine. Salmonella derby and Salmonella agona are emerging serotypes in swine. A lot of Salmonella are isolated in nurseries. High pressure washing may aerosol Salmonella. Bronchiolar and ileocolic lymph nodes are good tissues to culture for the isolation of Salmonella. High doses of Salmonella appear to cause immunosuppression. Coinfection with PRRSV and Salmonella produces more clinical signs than Salmonella alone. Salmonella species are often found in swine barn dust and in ventilation fans. Salmonella choleraesuis is not a frequent pathogen for humans but when it occurs the mortality rate is high.
