Antibiotic susceptibilities of swine Salmonella isolants from 1979 to 1983.

Two hundred seventy-seven Salmonella (27 serotypes) were isolated from Kansas swine over a 5-year period (1979 to 1983). Salmonella cholerae-suis was the predominant isolant from all tissues and made up 94.4% of the Salmonella isolants from the lungs. The percentage of Salmonella isolants susceptible to various antimicrobial agents was determined. The percentage of Salmonella susceptible to carbadox decreased from 1980 to 1983.
