Neurologic disease in naturally occurring Salmonella choleraesuis infection in pigs.
A granulomatous meningoencephalomyelitis was seen in 17 feeder pigs submitted for diagnostic evaluation from eight farms. Vasculitis and destructive microgranulomas were widespread in both brain and spinal cord. Occasionally there were microabscesses. Salmonella choleraesuis var. kunzendorf was isolated from six of the eight groups, and there were lesions of acute salmonellosis in all animals examined. In three of the affected herds the principal disease manifestation was neurologic.
