title: [Immunizing against salmonella infections with live and inactivated vaccines].
abstract: A live attenuated auxotrophic S. typhimurium (S. tm.)-mutant was used by orally administration via drinking water several times during rearing, combined with 1- or 2-times parenteral injection of an autogenous S. enteritidis (S. e.)/S. tm.-oil emulsion vaccine. In a 8-month period, more than 500,000 birds were vaccinated. The vaccine was safe. Challenge test showed protection in the vaccinates and their offspring. The number of isolates in the farms detected by regular monitoring decreased. The protection of the live-culture mutant lasted about only 8 to 10 weeks. A. S. tm.-mutant more potent for chickens will be tested now. We consider vaccinations as one important factor in a salmonella control program, especially for commercial layers and broiler breeders.
