Abstract:
The efficiency of the live vaccine Zoosal T with a double marker mutant of Salmonella Typhimurium was tested on conditioned pigeons. For challenge infection we used a pigeon specific variation copenhagen strain in a defined state of virulence. The reduction of mortality and the persistence of Salmonella in organs were evaluated. An oral booster enhances the protection due to vaccination.
