title: Immunization of calves against salmonellosis.
abstract: Salmonella typhimurium bacterins, containing adequate antigenic mass, protected calves against clinical signs of salmonellosis and death. Protection against salmonellosis was correspondingly reduced when the bacterin was diluted 1:10 and 1:100. A mouse protection test revealed that 17 of 18 (94%) of the S typhimurium-containing bacterin serials produced in 1977 stimulated adequate immunity.
