Technical Abstract: The veterinary component of the National Antimicrobial Resistance Monitoring System (NARMS) identified 8527 Salmonella isolates from swine samples in the years 1997-2003. Fifty-one Salmonella serotypes were identified from 3147 diagnostic, 2138 on-farm, and 3246 slaughter samples. The most frequently identified serotypes were Derby, Typhimurium var. Copenhagen, Typhimurium, Heidelberg, Infantis, Anatum, Johannesburg, and Agona. The top three serotypes from each sample type were as follows: Diagnostic; Cholera-suis (28.6%), Typhimurium var. Copenhagen (18.0%), Derby (9.5%); On-farm: Derby (18.5%), Agona (16.7%), Typhimurium var. Copenhagen (7.7%); Slaughter; Derby (25.4%), Typhimurium var. Copenhagen (10.6%), Johannesburg (6.7%). Six serotypes (Derby, Typhimurium var. Copenhagen, Typhimurium, Heidelberg, Anatum, Agona) were found among top serotypes from each sample type. S. choleraesuis was found primarily in diagnostic samples, and S. Johannesberg and Schwarzengrund were found primarily in slaughter samples. Only two of the top five slaughter isolates, Typhimurium and Infantis, were also seen on the 2002 CDC top 10 list of human isolates.
